Throttle Position Sensor, Contactless - Dual Output - TPS280DP

Product Brand: Penny & Giles

Throttle position sensors, otherwise known as TPS, are designed to track the throttle position of a vehicle. This sensor is able to closely monitor the throttle as it is typically directly positioned on the butterfly spindle, or shaft, of the vehicle.

A variant of the popular, contactless rotary throttle positioning sensor range, this dual output throttle position sensor uses a factory programmable non-contact, Hall-effect sensor system.

Throttle position sensor: the design & performance

The TPS280DP is designed as a modern alternative throttle positioning sensor, to the rotary potentiometers fitted on a high-performance race car and motorcycle induction systems. It replaces a potentiometer as it will eliminate premature failure due to electrical noise – caused by potentiometer wear. The TPS280DP is life tested to 30-million cycles (60 million operations), more than NINE TIMES that of a potentiometer in this application.


Design options

  • 200 or 500mm cable lengths 
  • Sealing to IP69K, able to withstand high-pressure wash-downs
  • Operates from 5Vdc (and 9-30Vdc)
  • Connector: Not fitted (C0) or Mini Sure Seal MSS4R fitted (C1)
  • Factory programmed to allow a wide range of configurations
  • Output direction: Both clockwise, both anticlockwise or one CW, one ACW

The 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. 


Throttle position sensor: mechanic & electrical specification

The TPS280DP provides contactless technology with a range of electrical features and output options. 


Electrical features

  • Supply voltage Vdc: 9 to 30 (unregulated) and 5 ±0.5 (regulated)
  • Over voltage protection Vdc: Up to 40 (-40 to +60°C)
  • Maximum supply current mA: <25
  • Reverse polarity protection: Yes
  • Output to GND: Yes
  • Output to supply: In 5V regulated mode only
  • Power-on settlement time S:<1
  • Resolution: % 0.025 of measurement range (12 bit)

  • Temperature coefficient ppm/°C <±30 in 5V supply mode: <±90 in 9-30V supply mode

*Non-linearity is measured using the Least-Squares method on a computerised calibration system


OEM Options

Outputs can be programmed to provide: non-linear laws; switch outputs; clamp voltages; different output phasing CH1/CH2; faster input/output delay; extended analogue range; and output mapping for potentiometer replacements.


Sensor Applications

Throttle position sensors are used in a variety of applications including automobiles and racing, designed to suit the most rugged applications.
