Curtiss-Wright introduces SRH 301 + SRH 302 rotary position sensors

April 12, 2016- Curtiss-Wright’s Industrial division announced the launch of the SRH301 and SRH302 shaft-operated, rotary position sensors for OEMs designing vehicles and control systems.

With a low-profile sensor body depth of 17.3mm, and using 28mm diameter flanged housing with crush-proof mounting zones, these sealed IP69K-rated sensors perform against water, dust, shock, vibration and temperature. The SRH301 and SRH302 rotary position sensors are usable in challenging environments for medium-volume applications where a wide range of options or degree of customization may be required.

The sensors can be powered from either a 5Vdc regulated supply or from a varying voltage in the range of 9-30Vdc, such as a vehicle’s battery.

  • SRH301: The SRH301 is a 3-wire, single output variant with a supply current rating of less than 17.5mA.
  • SRH302: The SRH302 is a 6-wire, dual-redundant output variant with a supply current rating of less than 35mA. The dual-die sensor has two completely independent power connections and output channels for full electrical redundancy.

All variants of the SRH301 and SRH302 rotary position sensor use Hall-effect sensing technology to provide a long mechanical life. There is a choice of two shaft configurations, both compatible with existing industry standards for inter-changeability on existing equipment. The electrical output spans of both models can be set to correspond to rotations of 20° to 360° in 1° increments. Factory-programmable electronics can be set to one of two analog voltage output ranges (0.5-4.5V or 0.2-4.8V) or one of three PWM frequencies.

Connection options are industry-standard AMP Superseal or Deutsch DT04 series connectors, or 18AWG flying-leads for customer termination. The sensor can also be supplied with a protective NC10 flexible conduit for the cabling.
