SRH220DR Series
5Vdc or 9-30Vdc, Contactless Rotary Sensor, Dual-Redundant Outputs, Hall Effect Technology, Measurement Range from 0-20° to 0-360° in 1° Increments.
The SRH220DR is a dual-redundant output, contactless, rotary position sensor with integrated 6-way connectors, using a factory programmable Hall effect sensor system. SRH220DR operates from either 5Vdc regulated or 9-30Vdc unregulated power supply and is available with analog (0.1-4.9, 0.5-4.5 or 0-10Vdc) or digital (PWM) output signals.
This sensor is factory programmable, allowing you to specify the output signal type, the measurement range (0-20° to 0-360° in 1° increments) and the output direction (clockwise or anticlockwise).
The SRH220DR provides reliable and accurate rotary position measurement in extreme industrial environments, such as specialist off-highway construction and agricultural vehicles, where shock, vibration, and extreme temperatures can occur.
