Rotary position sensors
Curtiss-Wright’s Industrial division has launched the SRH301 and SRH302, a range of shaft-operated, rotary position sensors for OEMs designing vehicles and control systems.

With a low-profile sensor body depth of 17.3mm, and using a 28mm diameter flanged housing with crush-proof mounting zones, these sealed IP69K-rated sensors are said to offer exceptional performance against water, dust, shock, vibration and temperature. The sensors – from the Industrial division’s brand family of Penny & Giles – are suitable for use in challenging environments and as a cost-effective solution for medium-volume applications where a wide range of options or degree of customisation 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.
The SRH301 is a 3-wire, single output variant with a supply current rating of less than 17.5mA, while 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 wear-free Hall-effect sensing technology to provide a long mechanical life. There is a choice of two shaft configurations, both compatible with existing de-facto industry standards for straightforward 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 (0.5-4.5 or 0.2-4.8V) or one of three PWM frequencies.
Connection options are industry-standard AMP Superseal or Deutsch DT04 series connectors, or simple 18AWG flying-leads for customer termination. The sensor can also be supplied with a protective NC10 flexible conduit for the cabling.
