5Vdc or 9-30Vdc, Contactless Rotary Sensor, Dual Output, Hall Effect, Analog or Digital (PWM) Output, Sensor Measurement Range from 0-20° to 0-360°.
The Penny & Giles SRH280DP Rotary Sensor is a legacy product used by existing customers. For new installations and applications, we recommend selecting the modern equivalent Penny & Giles SRH301 & SRH302 Rotary Postion Sensor.
The Curtiss-Wright (Product Brand: Penny & Giles) SRH280DP is a contactless rotary position sensor, which uses a factory-programmable, non-contact, Hall effect sensor system. SRH280DP operates from either 5Vdc regulated or 9-30Vdc unregulated power supply and is available with analog (0.5-4.5Vdc) or digital (PWM) output signals.
The 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 sensor has a 12-bit resolution (0.025%) over the selected measuring range, and operates from -40 to +140°C when powered at 5Vdc.
