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 principle of centrifugal force. Once a set limit speed is exceeded, the switch will indicate speed tripping via dedicated electrical outputs when opening/closing. These outputs can close/break a contact or a relay with 230V and 6A. Overspeed monitoring combined with normal incremental outputs makes the MA450 suitable for use in safety-related applications.
Features MA450 overspeed switch + incremental encoder
The extremely robust design and the encapsulation of the encoder series make them 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 a 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.
