VDO SENDER UNIT 2159-0 Datasheet

The Sender Unit is designed for transforming the  

rotatory movement of the speedometer drive shaft 

(characteristic coefficient of the vehicle) into electrical 

pulses. The rotations are captured by a Hall IC.

The pulses supplied by the Hall IC are used by  

tachographs and on-board computers for capturing 

the distance covered and the road speed.

This technology has the major advantage that only 

an electrical lead is to be placed in the vehicle,  

instead of a mechanical drive shaft.

Features

• Double pulse (inverted)

• Mechanical input

• Static measuring

• Hall IC technology

• Suitable for road speed and engine 

  speed measuring

• Independent of sense of rotation

• Can be sealed

Applications

• For tachographs/EC tachographs KTCO 1318, 

  FTCO 1319 and MTCO 1390 NEC

• Generally for devices requiring an electrical

  pulse (double pulse, inverted) for road speed

  and/or distance measuring.
