Notes on CE Identification
The following applies to EDS eddy current long stroke displacement sensors:
-- EU directive 2004/108/EC
-- EU directive 2011/65/EC, “RoHS” category 9
Products which carry the CE mark satisfy the requirements of the quoted EU directives and the European
standards (EN) listed therein. The EC declaration of conformity is kept available according to EC regulation,
article 10 by the authorities responsible at
MICRO-EPSILON MESSTECHNIK
GmbH & Co. KG

The measuring system is designed for use in industry and satisfies the requirements.
1.4
Proper Use
-- The sensors are used for
ƒƒ displacement measurement in presses, punches, rolling mills, ect
ƒƒ position determination of piston in hydraulic and pneumatic cylinders
-- The sensors may only be operated within the limits specified in the technical data, see Chap. 2.3.
-- Use it in such a way that with malfunctions or total failure of the sensor, persons are not endangered and
machines are not damaged.
-- Take additional precautions for safety and damage prevention for safety-related applications.

Functional Principle, Technical Data
2.1
Measuring Principle
The eddy current long stroke displacement sensors transform a linear motion (for example piston position in
hydraulic cylinders) into a linear, electrical signal. An aluminium tube, moving concentrically around a sensor
rod, is used as target. Energy is transferred from the coil by inducing of eddy currents in the aluminium tube
and it is detuned as a result. The integrated, miniaturized electronics convert the tube position into a linear,
electrical output signal. The eddy current measuring principle works without contact between moving parts
and is therefore free of wear.

2.2
Structure
A coil is mounted inside the sealed rod, protected against environmental influences. The micro-electronics is
integrated in the sensor housing. A pressure-proof, stainless steel housing is available as an option. The sensors are used for measuring lengths from 100 to 630 mm.
Electrical connection:
-- Connector 4-pins, type Amphenol C164P compact (Model EDS-...-S...)1
-- Connector 7-pins, type Binder 712 (Model EDS-...- S ...7...)
-- Connector 5-pins, CA02COM-E14S with bayonet connection (Model EDS-...-F...)
-- Wire, axial (model EDS-...-Z...)

Installation and Assembly
4.1
Precautionary Measures
The measuring tube must not contact the sensor rod during operation.
>> Damage to or destruction of the sensor through abrasion is possible.
Do not deform or shorten the measuring tube.
>> Loss of specified technical data.
Do not crush the O-ring or damage through sharp-edged items.
>> Loss of functionality
4.2
Measuring Tube Guide and Fastening
Mount the measuring tube in the piston bore hold.
The dimensions for the measuring tube are shown, see Fig. 8 et seq. When the piston is moved in the measuring tube must not touch the sensor shaft. Observe the measuring tube position at the zero point
(= 4 mA output), see Fig. 2 et seq. A slightly eccentric mounting of the measuring tube has no negative influence on the sensor signal.
Mount the measuring tube in the piston by means of pressing or glueing.
Spot clamping is not permissible.

Load Resistor, Maximum Operating Temperature
The sensors are connected according to the pin assignment shown, see Fig. 18 et seq. (all series). Notice the
different criterias:
-- RL max = (UB - 10 V) / 20 mA
-- RL min = 82.5 * 1/V * UB - 1625 Ohm
-- Tmax = 150 °C - 3.3 °C/V * UB + 0.04 °C/W * RL
The maximum load resistor RL is limited by the operating voltage UB.
RL max =
(UB - 10 V)
20 mA
A small load resistor loads the sensor electronics more thermical. With a maximum operating temperature of
85 °C (+185 °F) the minimum load resistor RL permitted is calculated as:
R L min =
82.5 * U B
- 1625 Ohm
V
(If the result is negative: RL = 0 Ω)
With a preset load resistor the maximum operating temperature permitted is calculated as:

Operation
The sensors have no adjustment and setting elements.
After assembly and connection of display/output device the sensor should warm-up 10 minutes to be ready
for operation.
Output signal: 4 mA (start of measuring range) up to 20 mA (end of measuring range)

The sensor is ready for measuring without adjustment.
Warm-up time: 10 min.
Output signal: 4 ... 20 mA
Operation and Maintenance
Observe the notes on measuring tube guiding during operation, see Chap. 4.2.
Imperfect measuring tube guiding can lead to increased wear and premature defects.
The warranty and all liability claims are null and void if the device is worked on by unauthorized persons.
Repairs are to be made exclusively by MICRO-EPSILON.

7.
Warranty
All components of the device have been checked and tested for perfect function in the factory.
In the unlikely event that errors should occur despite our thorough quality control, this should be reported
immediately to MICRO-EPSILON MESSTECHNIK.
The warranty period lasts 12 months following the day of shipment.
Defective parts, except wear parts, will be repaired or replaced free of charge within this period if you return
the device free of cost to MICRO-EPSILON MESSTECHNIK.
This warranty does not apply to damage resulting from abuse of the equipment and devices, from forceful
handling or installation of the devices or from repair or modifications performed by third parties.
No other claims, except as warranted, are accepted. The terms of the purchasing contract apply in full.
MICRO-EPSILON will specifically not be responsible for eventual consequential damages.
MICRO-EPSILON always strives to supply the customers with the finest and most advanced equipment.
Development and refinement is therefore performed continuously and the right to design changes without
prior notice is accordingly reserved.
For translations in other languages, the data and statements in the German language operation manual are
to be taken as authoritative.

Decommissioning, Disposal
Disconnect the power supply and output cable at the sensor respectively the cylinder.
Do the disposal according to the legal regulations (see directive 2002/96/EC).
