Curtiss-Wright SRH520CN

Contactless, Hall-Effect, Rotary Sensor, CAN-bus Output, Measurement Range 360°

The Curtiss-Wright (Product Brand: Penny & Giles), SRH520CN is a contactless, rotary sensor much like the SRH501/2P model, but with additional integrated electronics to provide a CAN-bus interface according to ISO/DIS 11898.

Model SRH520CN is designed to meet the harsh operating requirements in heavy-duty, industrial position-sensing applications, including construction, agricultural, military and utility vehicles, as well as a variety of uses in steelworks, marine equipment and power generating plants.

  • Contactless – Hall-effect technology
  • J1939 or CANopen output
  • Measurement range 360°
  • 14-bit resolution (0.022°/LSB)
  • CW or ACW output
  • Rugged housing design, in marine-grade aluminum
  • Superior shaft strength
  • Shaft sealing to IP69K; connector sealing to IP67
  • M12 5-pin connector for easy installation
  • World-leading availability

This contactless rotary sensor has shaft side protection to IP69K, with minimum IP67 protection at the rear when the mating connector is attached and fully engaged. The SRH520CN incorporates a 14-bit, non-contact, Hall effect sensor with microprocessor control – offering 0.022° resolution.
