The High Resolution Wheel Pulse Transducer Assembly is used as an accurate rotation sensor mounted outboard of a vehicle wheel. The rotation sensor is used to measure rotational velocity, angular position, and direction of rotation. The output signals generated by the sensor can be used to determine wheel speed, acceleration, distance, and vehicle speed.


The assembly consists of electronics in a rugged housing, which is attached to a wheel plate and mounted on the customer wheel using collet lug extensions.

The WPT is very rugged and has been designed to accept contacting rotary seals. Units ordered with these seals are weatherproof with an IP67 rating. For higher speeds in dry conditions, order units without the contacting rotary seals.

Encoder options

Optical encoder resolutions ranging from 50 to 5,000 are offered. Each of these encoder choices have four outputs. Outputs A and B are in quadrature, meaning they are 90° out of phase. Output I is an index pulse. Output A⊕B is the exclusive OR of A and B, which doubles the basic resolution of the encoder. The outputs, 0 to 5 volt pulses, can drive TTL loads.

Signal conditioning

Optional EC-LV unit is available for the encoder signal output conversion into an analog signal. The EC-LV conditioner converts 0-5 V digital pulses to linear voltages proportional to angular position and angular velocity. The external switches allow the user to select the speed range and direction of rotation. It outputs angular position and velocity signals, in addition to the four encoder signals.
