Description
LS501-10P/1250/R5k L0.25%/KB is a draw-wire encoder made by LARM designed for measuring linear travel and length. The movement of the measured object is transmitted to the winding mechanism by a stainless steel wire. Rewinding of the wire is ensured by a spring.
This specific variant uses a multi-turn potentiometer. The position of the wire is therefore represented by a change in electrical resistance and provides absolute analogue position information. After the system is switched off and on again, it is not necessary to calculate the position from pulses as with the incremental version.

Measuring principle
The encoder is firmly fixed to the machine base and the end of the wire is connected to the moving object. As the object moves, the wire unwinds from the drum and turns the multi-turn potentiometer. The change in position is converted into a corresponding change in resistance. The spring mechanism ensures rewinding and keeps the wire tensioned.
The potentiometric version provides an absolute position value. It is therefore suitable where simple analogue position information is required without the need to count pulses.
Typical applications
- measuring stroke and linear travel,
- material feeders,
- lifting and handling equipment,
- measuring the position of moving machine parts,
- simple positioning and measuring systems.
Do not let the extended wire rewind abruptly on its own. Uncontrolled rewinding can damage the wire or the winding spring. During operation, the wire must be guided smoothly and without mechanical stress outside the measuring direction.
Mounting the draw-wire encoder
Make the electrical connection with the power disconnected. At temperatures below −5°C, the connecting cable must be firmly fixed. The bending radius of the cable must not be less than ten times its diameter.
In wet environments or where liquid may run or splash onto the encoder, mounting with the wire outlet facing upwards is not recommended. Before mounting, also check straight guidance of the wire along the entire working path.
FAQ
No. This specific variant uses a multi-turn potentiometer and provides absolute analogue position information. The LS501 series can also be manufactured in an incremental version, but that is not this variant.
The measuring length is 1250mm. One revolution of the winding mechanism corresponds to a travel of 125mm.
The designation specifies a potentiometer with a resistance of 5kΩ and a linearity of 0.25%.
KB denotes the side version of the BINDER connector.
The technical data are based on the documentation of the LARM LS501 series and the specific order version LS501-10P/1250/R5k L0.25%/KB.
