Curtiss-Wright SRS880

10º to 350º in 10º Increments, Submersible Rotary Sensor, Depth of 2m Equal to 6.5 Feet, Rugged 88mm Dia. Housing, IP68M Protection

The Curtiss-Wright (Product Brand: Penny & Giles), the SRS880 submersible rotary sensor has been specially developed to meet the harsh operating requirements of today´s 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).

  • Rugged 88mm housing design, now available in aluminum or stainless steel
  • Superior shaft strength with double-bearing support.
  • Sealed to IP68M – tested to a 2m depth
  • Electrical angles from 10 to 350° in 10° increments
  • M12 connector for easy installation.
  • Mating cabled socket with 2m or 5m cable length
  • World-leading availability – we can supply any one of 35 different angles in less than ten days from ordering -faster than our competitors.

The SRS880 uses the proven long life Penny & Giles hybrid potentiometer track technology (conductive plastic on the wire), providing high stability under extremes of temperature and humidity, with virtually infinite resolution and a life in excess of 20-million operations.

    Circuit Recommendation Hybrid track potentiometers feature a high wiper contact resistance, therefore operational checks should be carried out only in the voltage divider mode. Hybrid track potentiometers should be used only as voltage dividers, with a minimum wiper circuit impedance of 100 x track resistance or 0.5MΩ (whichever is greater). Operation with wiper circuits of lower impedance will degrade the output smoothness and affect the linearity -
