Curtiss-Wright launches new rotary position sensor

Shaft-operated WM-H10 features two independent, electrically-isolated outputs and is ideal for hostile on/off highway applications

Curtiss-Wright’s Industrial division has today announced the launch of the WM-H10, a shaft-operated rotary position sensor featuring a solid-state, Hall-effect sensor that offers two independent and electrically-isolated outputs. Contained in a compact housing with integrated connector, the new sensor’s robust, mechanical design offers exceptional levels of performance and is ideal for use in hostile, on- and off-highway vehicle environments.

Commenting on the launch, Kevin Rayment, Senior Vice President & General Manager of the Industrial division says: “The launch of the WM-H10 sensor showcases Curtiss-Wright’s commitment to continuous development and engineering excellence and, as we continue to look at providing engineered solutions to our industrial customers and markets, the launch also serves to grow our portfolio of rotary position sensor options.”

The full range electrical output of the WM-H10 rotary position sensor can be set to correspond to maximum rotations from 15° to 360. This provides a dual linear output voltage proportional to the absolute position of the 6mm, D-profiled shaft in either direction from a reference angle. To avoid errors associated with air-gap fluctuations, an integral magnet arrangement ensures a consistent sensor-magnet separation.

The two independent measuring circuits, each with its own +5Vdc power supply connection, enable the use of algorithms that compare the signals for error checking. By using the first output signal as the source of rotational motion detection, and the second signal for diagnostic purposes, comparing the positional data from both outputs, signal veracity can be determined, meaning high-performing, safety-critical applications can easily be addressed. Further integrity is also provided as the outputs enter pre-defined states in the event of connection errors to the sensor.

Additional features of the WM-H10 rotary position sensor include:

  • Fail-safe outputs

  • IP68/IP69K-rated for water and dust, shock, vibration and temperature

  • Operating temperature from -40°C to +85°C (SAE J1455)

  • Lifespan 10 million cycles @ 1Hz

  • MTTFd >1000 years

  • Packard Electric ‘Metri-Pack’ 150 series connector
