NADS3
Screw-in speed encoder with keyed coupling, square wave signal
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.
