angular position sensor / non-contact / Hall effect / IP69K

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.

The SRH301 range has a single output, while the SRH302 contains two completely independent measuring circuits, each with its own power supply, meaning high-performing, safety-critical applications can easily be addressed. The versatile, factory-programmable electronics can be easily set to one of two analog voltage output ranges or one of three PWM frequencies. In addition, the polarities of each of the analog outputs can be independently set.
