Mechanical engagement with the rotating portion of the sensor is via a slotted cavity, while the electrical output span corresponds to a rotation of 48.5°.

Operation is from a 5V supply, typically derived from the electronic control unit to which the sensor is connected. Dual on-board circuits are electrically isolated from each other, so providing truly independent voltage outputs – one at 50% the level of the other – thereby allowing the host electronics to detect output errors. Further integrity is provided as the outputs enter pre-defined states in the event of connection errors to the sensor. PWM output options are also available on request.

A robust mechanical design offers exception 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.

Connection to the WM-830 is via the industry-standard, Packard Electric ‘Metri-Pack’ 150 series of connectors, which offer high-reliability performance across all operating conditions.
