Penny & Giles SRH301 & SRH302

The Penny & Giles  SRH301 and SRH302 range of shaft-operated Rotary Position Sensors offers the optimal combination of performance, safety and cost.

The SRH301 and SRH302 range of shaft-operated Rotary Position Sensors offers the optimal combination of performance, safety and cost. The sensor utilises proven Hall-effect, sensing technology in a low-profile (17.3mm) housing with integral magnet.

The circuit design allows the sensor to be run from a regulated 5V supply or a varying voltage in the range of 9-30V, such as a vehicle’s battery.

The electrical output span can be set to correspond to rotations of 20° to 360°, and the positional information is determined by the angle of the integral magnet relative to the sensor. The integral magnet arrangement ensures a consistent sensor-magnet separation, avoiding errors associated with air-gap fluctuations.
