MA450 overspeed switch + incremental encoder
Incremental encoder for speed feedback with integrated mechanical overspeed switch.
The MA450 series is a range of encoders that support combinations with integrated speed monitoring switches. The overspeed detection is based on a mechanical centrifugal principle. As soon as a set limit speed is exceeded, the switch indicates the speed trip via dedicated electrical outputs when opening/closing. These outputs can close/break a contact or relay with 230V and 6A. The overspeed monitoring in conjunction with normal incremental outputs makes the MA450 suitable for use in safety-related applications.
Characteristics MA450 overspeed switch + incremental encoder
The extremely robust design and encapsulation of the encoder series make it suitable for use in marine or offshore environments. Mines & cranes are two other suitable areas of application for the encoder series.
Mechanically, the MA450 series is based on an 11mm solid shaft with keyway to prevent slippage. The mounting flange is compatible with previous tachogenerator interfaces including a B10 mounting flange. The entire construction is made of high quality stainless steel.
