SRH880P Series

5Vdc or 9-30Vdc, Contactless, Submersible (submerged depth of 2m equal to 6.5 feet), Analog or Digital Output, Hall-Effect, Superior Shaft Strength.

TheSRH880P is a submersible, the contactless rotary sensor has been specially developed 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 and power generating plants.

This model can operate at a submerged depth of 2m (6.5 feet). The SRH880P sensor operates from 9-30Vdc unregulated or 5Vdc regulated supply and is available with analog (0.5-4.5Vdc) or digital (PWM) output signals.

  • Contactless – Hall-effect technology
  • Single output channel
  • 5Vdc or 9-30Vdc supply
  • Total sensor measurement range from 0-20° to 0-360°
  • Analog or Digital (PWM) output
  • 12-bit resolution over the selected measuring range
  • Low noise level (1mVrms) on the output signal
  • Rugged 88mm housing design, available in aluminum or stainless steel
  • Superior shaft strength with double-bearing support
  • Operating temperature -40° to +120°C
  • Environmental protection to IP68
  • M12 connector for easy installation
  • Mating cabled socket with 2m or 5m cable length
  • Rapid availability

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 +120°C when powered at 5 or 9Vdc.
