The Yifeng Sensor WKPF linear displacement sensor manual provides applications, features, technical parameters, and installation guidelines.
This manual introduces the WKPF linear displacement sensor, a micro‑rod type device designed for flange‑mounting in coal‑mining, hydraulic, and cavity‑internal detection applications. It highlights the sensor's anodized housing, built‑in conductive plastic measurement unit, IP67 sealing, and two output options.
Technical specifications such as effective travel ranges, resistance values, linear accuracy, resolution, maximum speed, temperature range, and dimensions are listed, followed by detailed mechanical installation instructions, wiring recommendations, and grounding requirements. This manual is written in Chinese.

The sensor is rated IP67 for protection against dust and water.
The sensor can move up to 5 m/s when mounted vertically and up to 2 m/s when mounted horizontally.
The grounding resistance should be less than 1 Ω.
Use four‑wire or shielded cable with the sensor’s ground terminal connected, and ensure the shield is grounded at the control box.
