2.1 Intended use
The product (sensor) is used for sensing a position of a SCHUNK
module via a magnetic control cam or a specific magnetic field.
lThe product is intended for installation in a machine/
automated system. The applicable guidelines for the machine/
automated system must be observed and complied with.
lThe product may only be used within the scope of its technical
data, }3 [/7].
2.2 Inappropriate use
The product is not a safety component in accordance with the EC
Machine Directive 2006/42/EC and must not be used in safety-
relevant parts of machine control units.
2.3 Environmental and operating conditions
Required ambient conditions and operating conditions
Incorrect ambient and operating conditions can make the
product unsafe, leading to the risk of serious injuries,
considerable material damage and/or a significant reduction to
the product's life span.
lMake sure that the product is used only in the context of its
defined application parameters, }3 [/7].
lMake sure that the environment is free from splash water and
vapors as well as from abrasion or processing dust. Exceptions
are products that are designed especially for contaminated
environments.
2.4 Constructional changes

4 Assembly and settings
NOTE
The assembly instructions in this chapter are generally
applicable.
Module-specific assembly instructions for the sensor can be
found in the Assembly and Operating Manual for the module,
which can be downloaded at schunk.com
4.1 Mechanical connection
CAUTION
Property damage due to incorrect bending radius!
The product may get damaged if the cable's bending radius is
less than the minimum.
lStatic: 10 times the cable diameter.
lDynamic: 15 times the cable diameter.
CAUTION
Risk of damage to the sensor during assembly!
lObserve the maximal tightening torque.
Ferromagnetic components change the sensor's switching
positions, e.g. adapter plate made of construction steel. For
ferromagnetic adapter plates:
lFirst, install the module on the adapter plate.
lThen adjust the switching position of the sensor.
NOTE
lDo not use the sensor as a safety component.
lDo not pull on the cable of the sensor.
lSecure the cable and connection plug so that they are not
taught and cannot move during operation.
lDo not exceed the permitted bending radius of the cable.
lDo not allow the sensor to come into contact with hard
objects and chemicals (e.g., nitric acid, chromic acid and
sulfuric acid).
The sensor is an electronic component that can be sensitive to
high-frequency interference or electromagnetic fields.
lCheck whether there is sufficient distance between the sensor
and sources of interference and their supply cables.

4.3 Installing and connecting the sensor
Mechanical connection
1. Turn the sensor (1) into the groove (2),
Or:Push the sensor (1) into the groove (2) until it reaches the
clamping stop (3).
2. Secure the sensor (1) using the set-screw.
ðObserve the maximum tightening torque of 10Ncm.
3. Connect the sensor (1) and fasten the cable.
4. Secure the electronics with cable connectors to relieve the stress
on the cable.
ð Use the ribs on the electronics to fasten the cable.

4.4 Adjusting the sensor
4.4.1 Setting switching points in teach mode
NOTE
The difference between the teach and operating temperatures
must not exceed 30 K.
NOTE
Once the switching points have been set, the environment of the
sensor may no longer be changed.
1. Move module to Switch-off point for switching point 1 position.
2. Press the "Teach" button (2) for 2s.
ðLED 1 (1) flashes after 2s.
3. Briefly press the "Teach" button (2).
ðLED 1 (1) lights up once the switching point has been
taught.
ðLED 2 (3) flashes.
4. Move module to Switch-off point for switching point 2
position.
ðLED 1 (1) goes out as soon as the module leaves Switch-off
point for switching point 1.
ðLED 2 (3) flashes.
5. Briefly press the "Teach" button (2).
ðLED 2 (3) lights up once the switching point has been
taught.
4.4.2 Setting the hysteresis
The switch-off point of the end position can be manually
adjusted by adjusting the hysteresis.
A minimum and maximum hysteresis is defined based on the
magnetic field. This defines the distance between the switch-on
and switch-off point. The sensor prevents a hysteresis that is too
low when the hysteresis is adjusted. If the switch-off point is
taught too far away from the switch-on point, the switch-off
position close to the switch-on point is automatically used. The
switch-off point must then be taught closer to the switch-on
point.
