• A load must be used when power is applied to the sensor.
• A combination of short circuit and wrong wiring will cause
permanent damage, regardless of short-circuit protection.
• When connecting a connector fasten tightly by hand.

■ Mutual Interference
Erroneous operation due to mutual interference is caused when
sensors are installed in parallel or facing each other.
Separate the sensors by at least the distance specified in the
table below.

● When a nut is used
The permissible torque is different depending upon the
distance from the top of the sensor head. Tighten the body at
less than the maximum permissible torque shown below,
and always with the enclosed nuts and washers.
The tightening torque varies depending on the mounting
plate or housing, the nut and washer material, and the
condition of the mounting surface. Check that the torque is
suitable for the actual combination of items before use.

■ Points to be Aware of When Handling
• Do not swing the sensor by the cable.
• Do not pull the cable with excessive force.
• Do not use the sensor outdoors, or where it is surrounded by
chemicals (solvents, acids, alkalies, etc.).
• If bending the cable, keep R (the radius of the bend) ≥ (the
cable diameter) x 3 at least.
• When disposing of an FL7M Series switch, dispose of it
appropriately as industrial waste in accordance with
applicable bylaws and regulations.
■ Wiring cautions
• Route the wires of the sensor separately from power lines or
through an exclusive conduit. Otherwise, electrical noise or a
surge may cause faulty operation or damage.
• If an extension of the cable is necessary, use at least a
0.3mm2 wire of 100m maximum length.
• When using a commercial switching regulator, ground the
FG (Frame Ground) and G (Ground) terminals. Otherwise,
switching noise may cause faulty operation.
• When using a load to generate a transient current, connect a
current limit resistor between the load and the output
terminal. (Otherwise, the short-circuit protection may be
activated.)

Metals opposite the sensor's sensing face must be removed to
avoid false actuation.
Keep metals away from the sensors as specified below.
Shaded areas indicate surrounding metal other than the target

Handling Precautions
• Do not tighten the body by applying torque to the
indicator unit (plastic unit).
• Do not mount the body using a setscrew. Doing so
might damage the sensor.
