VDO SENDER UNIT 2159-0 Datasheet

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. www.vdo.com Sender Unit 2159-0x
