Procedure

Locate a sensing object at the sensing distance, set the sensitivity adjuster to the minimum scale position, and gradually increase sensitivity by turning the sensitivity adjuster clockwise until the incident light indicator ( red LED ) is ON.

Position A is where the indicator has turned ON.

Position B is when the sensing object is removed and the sensitivity adjuster is turned clockwise until the incident light indicator ( red LED ) is ON. Position C is where the adjuster is turned counterclockwise (reducing the sensitivity) from position B until the incident light indicator ( red LED ) is OFF.

When there are no background objects, the maximum sensitivity is position C.

Set the sensitivity adjuster to halfway between (A) and (C) (at the optimum sensitivity). Check that the stability indicator ( green LED ) turns ON according to whether the sensing object is there or not. There is not sufficient margin if it does not turn ON. If this is the case, reconsider the detection method.

Unlike conventional Photoelectric Sensors, the variation in the sensitivity of E3S-A Photoelectric Sensors is minimal. This means the sensitivity can be adjusted on only a single Photoelectric Sensor, and then the adjusters on the other Photoelectric Sensors can be set to the same scale position. There is no need to adjust the sensitivity of each Photoelectric Sensor individually.

Safety Precautions

WARNING

This product is not designed or rated for ensuring safety of persons.

Do not use it for such purposes.

Precautions for Correct Use

Do not use the product in atmospheres or environments that exceed product ratings.

Mounting

Position of Optical Axis of Through-beam Model

Unlike conventional through-beam sensors, the E3S-A

Through-beam Photoelectric Sensor incorporates 2 lenses.

The lens actually in use is the one marked with an arrow indicating the position of the optical axis. When using a Slit, attach it to the lens marked with the arrow.

Unused lens

Mounting Bracket (Provided)

The direction of the optical axis coincides with the machine axis of the E3S-A when the mounting screw is inserted into the lock hole of the Mounting Bracket. If the mounting surface and the screw hole are correctly aligned toward the sensing object (or toward the Retroreflector for a Through-beam

Sensor), the mechanical axis and optical axis will be aligned when the screw is inserted into the hole. Incident light will be detected, and time-consuming adjustment will not be necessary. (If, however, the mounting surface is not flat, adjustment of the optical axis may still be required.)

Adjust the position of the Sensor so that incident light points at the center. Make sure that the incident light is at a fixed position.

The maximum tightening torque of the screw is 0.53 N

.m max.

E39-S46 Through-beam Slits

(Accessory, order separately)

Use the rubber attachment with the metal cover if a slit width of 2 mm is required. (A Slit is not required in this case.) Insert the 0.5- or 1-mm Slit between the metal cover and rubber attachment if a slit width of 0.5 or 1 mm is desired.

These Slits fit into the rubber attachment.

E39-E6 Polarized Mutual Interference Prevention Filters for Through-beam Sensors

(Accessory, order separately)

• A set of 4 Filters are sold together for two Through-beam

Sensors (for 2 each for Emitters and Receivers). Order one for every two sets of Photoelectric Sensors.

• For mounting, refer to the figure of the Through-beam Slits.

Emitter

Receiver

Y = 0

Up to two units can be attached.

Note: The arrows on the Filters can be attached in either direction when two Sensors are mounted next to each other. The Filter attached to an Emitter and to the corresponding Receiver must be the same in direction of polarization or the Sensor will not function.

• The arrow printed on the cover indicates the direction of polarization. By attaching the Filters opposite to each other in polarization to the Emitters and the Receivers in rows, mutual interference can be prevented (in any case, the

Filter attached to an Emitter and to the corresponding

Receiver must be the same in direction of polarization or the

Photoelectric Sensor will not function).

Operating Mode Selection

As shown in the following illustration, the E3S-A has an operating mode selector on the panel where the Receiver connector is located.

With this operating mode selector, the E3S-A is in either Dark-

ON or Light-ON mode.

Turbo

Function (

Turbo

Switch)

The turbo function is effective with the turbo switch pressed, and the function is reset automatically when released.

With the turbo function switched ON, the light spot is visible even at a distance of 200 mm, making it easy to check the sensing position and the angle of the optical axis.

Precautions

(1)Do not keep the turbo switch pressed for longer than 3 minutes. (It will not break even if it is pressed for an extended period.)

(2)Pressing the switch may change the timer delay settings.

Set the timer after using the turbo function to check the optical axis.

(3)To press the switch, use a force of 9.8 N max.

Sensitivity adjuster

The OFF-delay timer adjuster is used as a turbo switch (black).

The intensity of the red spot will be increased, making visual confirmation much easier.

Using the E39-R5 Optical Axis Reflector for Throughbeam Sensors

(Accessory, order Separately)

Use this attachment when the set distance is long and adjustment is mechanically difficult with a sensing object.

The default operating mode is shown in the following table.

Emitter

• Attach the Reflector to the Receiver.

• Look at the Reflector from right behind the Emitter. The

Reflector should be bright with red light when the optical beam strikes the Reflector. If the Emitter has a turbo function, the Reflector looks brighter with the function switched ON.

• When the Reflector is removed, the light beam strikes the

Receiver.

C-1


Precautions for Correct Use

● Design

Power Reset Time

The Sensor will be ready to detect within approximately 100 ms after the power is turned ON.

If the Sensor and the load are connected to separate power supplies, turn ON the Sensor power before turning ON the load power. Any exceptions to this rule are indicated in Safety Precautions in individual product information.

Turning OFF Power

An output pulse may be generated when the power is turned OFF. It is recommended that the load or load line power be turned OFF before the Sensor power is turned OFF.

Power Supply Types

An unsmoothed full-wave or half-wave rectifying power supply cannot be used.

Mutual Interference

Mutual interference is a state where an output is unstable because the Sensors are affected by light from the adjacent Sensors.

The following measures can be taken to avoid mutual interference.

Countermeasure

Concept Through-beam Sensors Reflective Sensors

2

Use a Sensor with the interference prevention function.

Install an inference prevention filter.

Separate

Sensors to distance where interference does not occur.

If Sensors are mounted in close proximity, use Sensors with the interference prevention function.

10 or fewer Sensors: E3X-DA

@-S, E3X-MDA, E3C-LDA Fiber Sensors

Performance, however, will depend on conditions. Refer to pages E3X-DA-S/E3X-MDA and E3C-LDA.

---

Check the parallel movement distance range in the catalog, verify the set distance between adjacent

Sensors, and install the Sensors accordingly at a distance at least 1.5 times the parallel movement distance range.

If the workpieces move from far to near, chattering may occur in the vicinity of the operating point. For this type of application, separate the Sensors by at least 1.5 times the operating range.

Alternate

Emitters and

Receivers.

Close mounting of Sensors is possible by alternating the Emitters with the Receivers in a zigzag fashion (up to two Sensors). However, if the workpieces are close to the Photoelectric Sensors, light from the adjacent

Emitter may be received and cause the Sensor to change to the incident light state.

Offset the optical axes.

Emitter

If there is a possibility that light from another Sensor may enter the Receiver, change the position of the

Emitter and Receiver, place a light barrier between the

Sensors, or take other measures to prevent the light from entering the Receiver.

(Light may enter even if the Sensors are separated by more than the sensing distance.)

If Sensors are mounted in opposite each other, slant the

Sensors as shown in the following diagram. (This is because the Sensors may affect each other and cause output chattering even if separated by more than the

Sensor sensing distance.)

Type of noise

Common mode noise

(inverter noise)

Common noise applied between the mounting board and the +V and 0-V lines, respectively.

● Wiring

Cable

Unless otherwise indicated, the maximum length of cable extension is

100 m using wire that is 0.3 mm 2 or greater.

Exceptions are indicated in Safety Precautions in individual product information.

Cable Tensile Strength

When wiring the cable, do not subject the cable to a tension greater than that indicated in the following table.

Cable diameter

Less than 4 mm

4 mm or greater

Tensile strength

30 N max.

50 N max.

Note: Do not subject a shielded cable or coaxial cable to tension.

Repeated Bending

Normally, the Sensor cable should not be bent repeatedly.

(For bending-resistant cable, see

Attachment to Moving Parts

on page C-4.)

Separation from High Voltage (Wiring Method)

Do not lay the cables for the Sensor together with high-voltage lines or power lines. Placing them in the same conduit or duct may cause damage or malfunction due to induction interference. As a general rule, wire the Sensor in a separate system, use an independent metal conduit, or use shielded cable.

Power line

Work Required for Unconnected Leads

Unused leads for self-diagnosis outputs or other special functions should be cut and wrapped with insulating tape to prevent contact with other terminals.


C-3


Power Supply

When using a commercially available switching regulator, ground the

FG (frame ground) and G (ground) terminals.

If not grounded, switching noise in the power supply may cause malfunction.

● Mounting

Attachment to Moving Parts

To mount the Photoelectric Sensor to a moving part, such as a robot hand, consider using a Sensors that uses a bending-resistant cable

(robot cable).

Although the bending repetition tolerance of a standard cable is approximately 13,000 times, robot cable has an excellent bending tolerance of approximately 500,000 times.

Cable Bending Destruction Test (Tough Wire Breaking

Test)

With current flowing, bending is repeated to check the number of bends until the current stops.

● Adjustments

Optical Axis Adjustment

Move the Photoelectric Sensor both vertically and horizontally and set it in the center of the range in which the operation indicator is lit or not lit. For the E3S-C, the optical axis and the mechanical axis are the same, so the optical axis can be easily adjusted by aligning the mechanical axis.

● Operating Environment

Water Resistance

Do not use in water, in rain, or outside.

Ambient Conditions

Do not use this Sensor in the following locations. Otherwise, it may malfunction or fail.

(1) Locations exposed to excessive dust and dirt

(2) Locations exposed to direct sunlight

(3) Locations with corrosive gas vapors

(4) Locations where organic solvents may splash onto the Sensor

(5) Locations subject to vibration or shock

(6) Locations where there is a possibility of direct contact with water, oil, or chemicals

(7) Locations with high humidity and where condensation may result

Environmentally Resistive Sensors

The E32-T11F/T12F/T14F/T81F-S/D12F/D82F and E3HQ can be used in locations (3) and (6) above.

Optical Fiber Photoelectric Sensors in Explosive Gas

Atmospheres

The Fiber Unit can be installed in the hazardous area, and the

Amplifier Unit can be installed in a non-hazardous area.

<Reason>

For explosion or fire due to electrical equipment to occur, both the hazardous atmosphere and a source of ignition must be in the same location. Optical energy does not act as an ignition source, thus there is no danger of explosion or fire. The lens, case, and fiber covering are made of plastic, so this setup cannot be used if there is a possibility of contact with solvents that will corrode or degrade (e.g., cloud) the plastic.

<Ignition Source>

Electrical sparks or high-temperature parts that have sufficient energy to cause explosion in a hazardous atmosphere are called ignition sources.

Hazardous area Non-hazardous area

Sensing object

Amplifier Unit

Influence from External Electrical Fields

Do not bring a transceiver near the Photoelectric Sensor or its wiring, because this may cause incorrect operation.

● Maintenance and Inspection

Points to Check When the Sensor Does Not Operate

• If the Sensor does not operate, check the following points.

(1) Are the wiring and connections correct?

(2) Are any of the mounting screws loose?

(3) Are the optical axis and sensitivity adjusted correctly?

(4) Do the sensing object and the workpiece speed satisfy the ratings and specifications?

(5) Are any foreign objects, such as debris or dust, adhering to the

Emitter lens or Receiver lens?

(6) Is strong light, such as sunlight (e.g., reflected from a wall), shining on the Receiver?

(7) Do not attempt to disassemble or repair the Sensor under any circumstances.

(8) If you determine that the Sensor clearly has a failure, immediately turn OFF the power supply.

Lens and Case

The lens and case of the Photoelectric Sensor are primarily made of plastic. Dirt should be gently wiped off with a dry cloth. Do not use thinner or other organic solvents.

• The case of the E3ZM, E3ZM-C and E3S-C is metal. The lens, however, is plastic.

● Accessories

Using a Reflector (E39-R3/R37/RS1/RS2/RS3)

During Application

(1) When using adhesive tape on the rear face, apply it after washing away oil and dust with detergent. The Reflector cannot be mounted if there is any oil or dirt remaining.

(2) Do not press on the E39-RS1/RS2/RS3 with metal or a fingernail.This may weaken performance.

(3) This Sensor cannot be used in locations where oil or chemicals may splash on the Sensor.

M8 and M12 Connectors

• Be sure to connect or disconnect the connector after turning OFF the Sensor.

• Hold the connector cover to connect or disconnect the connector.

• Secure the connector cover by hand. Do not use pliers, otherwise the connector may be damaged.

• If the connector is not connected securely, the connector may be disconnected by vibration or the proper degree of protection of the

Sensor may not be maintained.

● Others

Values Given in Typical Examples

The data and values given as typical examples are not ratings and performance and do not indicate specified performance. They are rather values from samples taken from production lots, and are provided for reference as guidelines.
