Curtiss-Wright TPS280DP

5Vdc (and 9-30Vdc), Contactless, Throttle Position, Dual Output, D Drive, Sealed to IP68, 25mm Body with Crush Proof Flange, Raychem™DR25 Cable + Connector.

The Curtiss-Wright (Product Brand: Penny & Giles), TPS280DP is a variant of the popular, contactless rotary position sensor range, which uses a factory programmable non-contact, Hall effect sensor system.

Electrically interchangeable with potentiometers the TPS280DP is designed as the modern alternative throttle position sensor (TPS) to rotary potentiometers fitted on the high-performance race car and motorcycle induction systems. Replacing a potentiometer with the TPS280DP will eliminate premature failure due to electrical noise – caused by potentiometer wear.

TPS280DP is life-tested to 30-million cycles (60 million operations), more than NINE TIMES that of a potentiometer in this application.

  • Electrically interchangeable with potentiometers
  • More than 9x the life of a potentiometer
  • Extremely low signal noise, for the life of the sensor
  • Will operate from -40 to +140°C, with excursions to +170°C
  • Sealed to withstand high-pressure wash-downs (IP69K)
  • Mechanically interchangeable with potentiometers on 32mm mountings
  • Standard output is dual channel
  • Configurable output direction, for left or right fitment
  • Measurement range from 20 to 360° in 1° increments
  • 12-bit resolution (0.025%) over the angular range
  • Analog (0.5 – 4.5 or 0.1 – 4.9Vdc) or PWM outputs

TPS280DP is mechanically interchangeable with most existing throttle position sensors using 32mm mounting centers and is designed to interface with most common throttle body D-type spindles. The sensor has a choice of 200 or 500mm cable lengths, with or without an MSS4P Mini Sure-Seal connector fitted to the FDR-25 sheathed spec 55A cable. With sealing to IP69K, it is also able to withstand high-pressure wash-downs.
