VDO SENDER UNIT 2159-0 User manual

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.
