SRH301 & SRH302 - Hall-effect Rotary Position Sensor-1

Hall-Effect Rotary Position Sensor  Non-contacting Hall-effect technology  Simple mounting, low-profile design  Measurement angle 20-360°  5V or 9-30V supply options  Single- or dual-redundant-output options  Analog output – 0.5-4.5V or 0.2-4.8V  PWM output option  Fail-safe outputs  Sealing to IP69K  AMP or Deutsch connector options  Flying-lead option  Protective cable-conduit option The SRH301 and SRH302 range of shaft-operated Rotary Position Sensors offers the optimal combination of performance, safety and cost. The sensor utilises proven Halleffect, sensing technology in a low-profile (17.3mm) housing with integral magnet. 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. The circuit design allows the sensor to be run from a regulated 5V supply or a varying voltage in the range of 930V, such as a vehicle’s battery. The SRH301 and SRH302 both contain on-board diagnostic functions that mean the outputs can be put into safe, predefined states should an internal sensor error be detected. 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 sealed design offers exceptional levels of performance with respect to water and dust, shock, vibration and temperature, meaning the sensor is ideal for use in hostile, on- and off-highway vehicle environments. 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- Connection options are industry-standard AMP Superseal or Deutsch DT04 series connectors, or simple flying leads for customer termination. The sensor can also be supplied with a protective conduit for th
