Originally designed to monitor the height and movement of a series of aero struts on a Formula 1 car, the Rod Position Sensor is ideal for applications where a very small change in linear position needs to be monitored. The sensor is designed with a very low height profile and no internal moving parts, detecting up to 8mm of linear movement, with no physical contact between the sensor and the sensed part.

The Rod Position Sensor comprises two parts, the sensor and a separate metallic core pin activator. The sensor measures the linear position of the pin as it enters the bore of the sensor body. Commonly, the activator is formed as part of the existing mechanics for minimum installation overhead.
