The ST25-04 is a four-point non-contact displacement sensor designed for sensing linear, angular and rotary motion. It consists of a stationary 4-sensor base and a head plate, which is mounted over the application of interest. The linear version of the ST25-04 has a travel range of ±1 mm, an angular version with a range of ±30°, and a rotary version with a range of ±100°. Each sensor is secured with a mounting bracket, allowing for easy alignment in any orientation. Connections are made via 4-wire shielded cable, which provides power to the unit, and a digital output for connection to a PLC, DAQ, or other system. The sensing head utilizes MEMS technology, allowing for long life, robustness, and excellent accuracy and repeatability. The ST25-04 is an excellent choice for applications requiring non-contact motion measurement, such as rotary and linear actuators, automotive position sensing, robotic motion/position measurements and more.
