TPS280DP Contactless Throttle Position Sensor with Dual Output

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.

• 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
• Analogue (0.5 – 4.5 or 0.1 – 4.9Vdc) or PWM outputs

TPS280DP is designed as the modern alternative throttle positioning sensor (TPS) to rotary potentiometers fitted on 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.

TPS280DP is mechanically interchangeable with most existing throttle position sensors using 32mm mounting centres 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.

The TPS280DP operates from 5Vdc (and 9-30Vdc) and is factory programmed to allow a wide range of configurations.
