Angular sensor thrives in tough environments

Angular sensor thrives in tough environments

Using magnetoresistive (MR) technology to determine angular position, the SMART rotary configuration position sensor provides 360° non-contact position sensing, enabling design engineers to replace optical encoders or resolvers, which can be expensive and difficult to integrate. The sensor is well suited for high-accuracy measurement in dirty, harsh environments, including transportation (steering angle, articulation angle, boom-arm detection) and industrial (solar panels, wind turbines) applications.

The sensor determines the angular position of a magnetic collar attached to a rotating object with a resolution of 0.01°, reliably providing repeatable output with a typical sensor-collar air gap of ±2.0 mm and with radial misalignment up to a 2.50 mm. Automotive-grade potting makes the sensor more resistant to vibration, shock, and extreme temperatures. (Contact Robyn Seykora for pricing and availability.)
