This is to certify that the products
Classification Linearpotentiometer
Series LRW2, LRW3
fulfill the current request of the following EC-directi ves:
EMV-directive 2004/108/CE
applied harmonized standards:
EN 61000-6-2:2005, EN 61000-6-4:2007, EN 61326-1:2006
The declaration of conform ity loses its validity if the product is m isused or modified without proper
authorisation.

DECLARATION OF EC-CONFORMITY
All the data reported in this brochure and the data sheet, like linearity, lifetime, temperature coefficient are
valid for a sensor utilization as a ratiometric device with a max current across the cursor Ic ≤ 0.1 mA.
Do NOT use the position sensor as variable resist ance!
When calibrating the transducer, be careful to set the stroke so that the output does not drop below 1% or
rise above 99% of the voltage level.
MAINTENANCE
The sensors are maintenance free. It is not necessary to lubricate the moving parts.

FIRST STEPS
MOUNTING THE SENSOR
ELECTRICAL CONNECTION
WayCon Positionsmes stechnik GmbH would lik e to thank you fo r the trust you have placed in us and our
products. This manual will make you familiar with the installation and operation of our linear
potentiometers. Please read this m anual carefully before initial operation!
Unpacking and checking:
Carefully lift the device out of the box by grabbing the housing. After unpacking the device, check it for
any vis ible damage as a result of rough handling during the shipment. Check the delivery for
completeness.
If necessary consult the transportation c ompany, or contact WayCon directly for further assistance.

Sensor is to be used as voltage divider, using a maximum cursor current of Ic ≤ 0.1 µA (do NOT use the
sensor as variable resistance!). Please pay attention to the notes on the last page.

TECHNICAL DRAWING
Useful electrical stroke B: corresponds to the sensors measurement range
Theoretical electrical stroke C: actual length of the conductive path, that has to be longer than B, in order
to get a valid electrical signal at the start and end point of the measurem ent range.
When c alibrating the transducer, be careful to set the stroke so that the output does not drop below 1%
or rise above 99% of the voltage level.
