Description
Incremental encoder for velocity feedback with integrated mechanical overspeed switch. The MA450-series is a range of encoders supporting combinations with integrated speed monitoring switches. The overspeed detection is based on a mechanical centrifugal force principle. Once a set limit speed is exceeded will the switch open/close indication the speed tripping via dedicated electrical outputs. These outputs can make/break a Contact or relay with 230V and 6A. The over speed monitoring in conjunction with normal incremental outputs makes the MA450-suitable for use in safety related applications.
The extreme robust design and encapsulation of the encoder series make it suitable for use in Marine or Off-shore environments. Mines & Cranes are two other suitable fields of operation for the encoder series.
Mechanically is the MA450-series based on a ø11mm solid shaft with key-way to prevent slip. The mounting flange is compatible to previous tacho generator interfaces including a B10 mounting flange. The entire design is made out of high grade stainless steel.
