Product Description


Roundss RLC28D  draw wire distance sensor linear movements using a highly flexible steel cable.
The cable drum is attached to a sensor element which provides a proportional output signal.
Measurements are performed with high accuracy and high dynamic response. The use of high quality components guarantees a long life cycle and high operational reliability.

1. Certification: CE & ISO9001 & RoHS.
2.Feature: sturdy and durable, easy to install, optional various output mode, etc.
3.Manufacturer: quality control, better delivery control and better cost control.


Wrong wiring may damage the sensor
Make sure wire in the power off state
Do not let go after wire is pulled out, otherwise the sensor could be easily damaged
Do not exceed the total length of the wire
Please ensure the cleanness of the equipment and wire line to prolong the service life
Avoid external force
