Curtiss-Wright SRH301 & SRH302

Hall-Effect Rotary Position Sensor, Optimal Combination of Performance, Safety, and Cost, Hall-Effect, Low-Profile (17.3mm) Housing with Integral Magnet.

The Curtiss-Wright (Product Brand: Penny & Giles) SRH301 and SRH302 range of shaft-operated Rotary Position Sensors offer 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 utilizes proven Hall-effect, sensing technology in a low-profile (17.3mm) housing with an 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.
