Catalog excerpts

Rotary Position Sensor  No-contact, Hall-effect technology  Internal shaft  Measurement angle 48.5°  5V supply  Dual-redundant outputs  Fail-safe outputs  Voltage or PWM output options  Environmentally robust  Packard Electric ‘Metri-Pack’ 150 series connector The WM-830 is a cost-effective rotary sensor utilising proven Hall-effect technology to ensure accurate and reliable measurement of angular position. 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. 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°. 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. 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 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
