Features

Split design enables installation in confined spaces, especially inside hydraulic cylinders or machinery requiring compact sensors.

Non-contact, absolute linear measurement ensures long service life, no mechanical wear, and reliable, maintenance-free operation.

Ultra-high precision with resolution down to 1 µm, nonlinearity <0.01% FS (min. ±50 µm), and repeatability <0.001% FS (min. ±1 µm).

Rugged, fully enclosed design with IP68 protection and 304 stainless steel measuring rod withstands high pressure (up to 35 MPa continuous/70 MPa peak), humidity, and temperatures up to +125 °C.

Multiple output protocols—including Analog, SSI, Profibus-DP, CANopen, Start-Stop, Profinet, EtherCAT—enable seamless integration with virtually any industrial controller or network.

Installation and Use Instructions


Output characteristic


RD Series sensors are designed in a split form and are suitable for installation in cylinder, especially for cylinder applications in confined spaces. The sensor consists of two parts: a sensing rod and an electronic bin. The sensor rod is a pressure-resistant stainless round pipe with threads or flanges to provide protection for the sensing elements, and the whole sensor rod is installed in the cylinder through pistons. 

The temperature resistance of the sensing rod up to + 125℃, and the protection level reaches IP68, which is very suitable for harsh occasions such as high temperature, high humidity and water vapor; The electronic bin encapsulates the sensor signal processing part and the external interface together, reaching IP67 protection level, and can be connected with the sensor rod through the side or bottom of the connector plate.
