Hall-effect Speed Sensor HDD

Technical data sheet

Series 2

Dual sensor for contactless

speed measurement

Features

– Easy installation without adjustment

– Detects even low speeds

– Large temperature range

– Protection against Short-circuit, reverse polarity protection

– Pressure-resistant sensor measuring surface

– O-ring seal

– High type of protection IP69k

– Available in a set with A2FM and A6VM/E axial piston mo

tors

– Due to asymmetrical screw attachment the mounting of the

axial piston units is encoded.

Main components

– Two integrated Hall semiconductors with permanent magnet

and amplifier

– Robust plastic housing

– Moulded connecting cable

/8 Bosch Rexroth AG HDD RE 95 135/06.06 General Notes – The suggested circuits do not imply any technical liability of Rexroth for the system. – Lines to sensors must be shielded. The shield must be connected to the electronics on one side or to the machine or vehicle ground via a low-impedance connection. – Lines to the electronic unit must not be routed close to other power-conducting lines in the machine or vehicle. – A sufficiently large distance to radio systems must be maintained.
