NADS3–Speed encoder, aluminium, with 2 square wave signal outputs, 90° phase shift, rotational direction detection, high EMC protection, mounting with bracket or flange : NORIS Group GmbH

GC_Tachogeneratoren_GE120-121-122_1024x768px

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

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.
