•The danger of personal injury and danger of property damage due to a
malfunction of the sensor in machines or systems must be excluded by
additional safety measures.
•In safety-relevant applications, additional facilities must be provided for
maintaining safety and preventing damage.
•Check whether the protection class of the sensor is suitable for the application.
Risk of crushing and cutting injury due to pre-tensioned spring being released
from housing when opened!
•Do not open the sensor.
Risk of cutting injury due to uncontrolled retraction of the cable
•Do not damage the measuring cable!
•Do not let the measuring cable and the cable fixing spring back uncontrolled!

posiwire®Cable Extension Position Sensors with an integrated inclinometer are used to measure both linear
and inclination position at the same time. Both output parameters –linear position and inclination –are
independent of each other. For determining measuring range, environmental compatibility and connection
data of the sensor, please note the data sheet. Use the sensor as intended by operating within its specified
technical data and ambient conditions.
The installation and operating instructions supplied with the unit must be respected. All maintenance and
service work must be carried out. The data sheet of the respective sensor is part of this instruction manual. If
yet not available, it may be requested by stating the respective model number.
The sensor must not be improperly mounted, operated or serviced. In addition, operation of the sensor in
faulty condition is prohibited.

2 Transport and storage
Risk of damage to the measuring cable or cable fixing
•Do not lift the sensor by the cable or cable attachment.
Observe storage and transport temperatures according to the temperatures specified in the data sheet.
Max. rel. humidity 60%, dew condensation must be prevented at all times.
The device must be secured against slipping and tipping during transport.

Unpacking
Do not unpack sensor by pulling cable or cable clip.
Shipment damages
Check sensor immediately for shipment damage. In case of any damage, please contact your supplier.

Removing kink protection / Shipment protection
The kink protection prevents the cable fixing from buckling and damaging the cable. Remove in the direction
of the cable.
1. 2.
Transport protection (for some sensor models) prevents the measuring cable from being extracted before
mounting the sensor. Only remove immediately before mounting:
1. Carefully cut the crimped, short wire end directly at the sensor housing, without applying any axial force
to the wire
2. Pull the wire out of the case at the loop
For further transport, use the original packaging (if available) to avoid transport damage.

3.1 Mechanical installation
Risk of injury from touching the moving measuring cable or moving parts
during operation
•Operate the sensor only with a suitable protective device (e.g. cable cover) to
prevent injury!
Choice of installation position
•Select a protected installation position for the measuring cable.
This prevents damage of the measuring cable.
•Preferably mount the sensor with the cable outlet pointing downwards.
This prevents liquids from entering through the cable outlet.
•Screw the sensor onto a flat surface or provide a three-point mounting.
This avoids distortion and damage to the sensor.
•In harsh environments provide protection for the measuring cable.

Cable travel should only be axial to the cable outlet - no misalignment is
allowed
•Cable misalignment shortens service life of sensor and causes error in
measurement. Warranty will not be granted for damage caused by misalignment.
correct incorrect
Sensor with
horizontal extension
Sensor with vertical
extension
•If the measuring cable cannot be extended in the axial direction of the cable
outlet opening due to the measuring task, the SR2 cable pulley must be used to
redirect the cable.
•For special applications, extension cables with cable clips attached on both ends
are available.
Fixing the sensor
Depending upon the sensor model, holes in the base plate, threads, mounting brackets or T-slots in the
sensor housing enable attachment of the sensor. Required dimensions are listed in the data sheet.
Mount the sensor on flat surface.
Use flat washers and/or thread locker if necessary.
The torques of the fixing screws depend on the material used (see p.12).

Cable attachment device
The cable clip can be fastened as follows:
•M4 cable connection in cable outlet direction
The M4 connection is mounted with a
through hole, two washers and a M4
nut.
Do not rotate the M4 connection
during assembly, otherwise the
measuring cable will be twisted!
•Cable clip with Allen screw M5: standard fixing.
•Cable clip with attachment head (accessory GK1: metal, GK2: plastic): fast cable attachment, easy to
remove
•Cable clip with magnetic clamp (accessory MAG1): with this device the sensor can be easily used at
several measuring points with ferromagnetic surface.
