Speed encoders

Mechanically connected, screw-in speed encoder with 2 square wave output signals.

NADS3

Speed sensor NADS3

  • Speed sensor with two square wave output signals and rotational direction relay
  • Can be mounted in place of a tachogenerator
  • Can be loaded with 50 mA SINK and 20 mA LOAD
  • High EMC protection for harsh electrical environments
  • For harsh environments up to IP66

Description

Speed encoders of type NADS3 are 2-channel aluminium speed encoders and are fitted with a bracket or an installation flange for standard spigots on the shaft. The drive shaft of the speed encoder is connected directly to the speed source (e.g. motor, generator) by means of a coupling. The speed is converted into a square wave signal using a signal amplifier. Two square wave signals with a phase offset of 90° are available. These speed encoder are suitable for acquiring shaft speeds.
