1.3 Dust-ex proof marking
The Dust-ex proof marking according to the guideline 2014/34/EU is lasered on the sensor housing.
These are:
WS10EX:
II 3D
Ex tc IIIC T80°C Dc X
WS12EX
II 3D
Ex tc IIIC T80°C Dc
This means:
II
=
Equipment-group II: Equipment not intended for use in underground parts of mines, as
well as their overground plants, which are endangered by firedamp or/and combustible
dusts
3
=
Equipment category 3: Normal level of safety – application in dust explosion hazardous
areas. Equipment in this category is intended for use in areas in which explosive
atmospheres – in the case of this sensor caused by dispersed dust – are unlikely to
occur, or, if they do occur, are likely to do so only infrequently and for a short period
only. Equipment in this category ensures the requisite level of protection during normal
operation.
D
=
Air/dust mixture
EX
=
This symbol indicates that the electrical equipment complies with one or more types of
protection
tc
=
Ignition protection class: protection by enclosure IP65
IIIC
=
Group for conductive dust
T80°C
=
Maximum surface temperature of the Cable Extension Position Sensor
Dc
=
Equipment Protection Level (EPL): EPL „Dc“ complies with the categorie 3D
X
=
Resists an impact with reduced impact energy of 4J, without X the sensor resists an
impact of 7J impact energy

posiwire® Cable Extension Position Sensors are intended for linear position measurement of linear guided
objects. 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 environmental conditions are specified in the dust-ex proof category of the sensor.
The installation and operating instructions supplied with the unit must be observed and all maintenance and
service work must be carried out. The data sheet of the respective sensor is part of this instruction manual. If
not yet available, it may be requested by stating the respective model number.
The sensor must not be used in applications with an explosive gas atmosphere or higher explosive dust
atmosphere that requires a higher rated device.
Do not use the sensor in the following environmental conditions:
• abrasive dust e.g. dust including metal or metaloxid, stone dust, glass dust, ceramic dust
• corrosive and aggressive media e.g. atmospheres containing chloride.

2 Transport and storage
Loss of explosion protection in case of shipment damages
• Check sensor immediately for shipment damage.
• Damaged sensors may no longer meet the specified EX rating and must not be
mounted and operated in explosion-risk areas.
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 operating temperature (see data sheet).
Max. rel. humidity 60%, condensation must be excluded.
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.

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.13).
