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. Overspeed detection is based on a mechanical centrifugal force principle. When a set speed limit is exceeded, the switch opens/closes, indicating the speed trip via dedicated electrical outputs. These outputs can close/break a contact or relay operating at 230V and 6A. Overspeed monitoring, combined with standard incremental outputs, makes the MA450 suitable for use in safety-critical applications.
Characteristics MA450 Overspeed Switch + Incremental Encoder
The extremely robust design and encapsulation of the encoder series make them suitable for use in marine or offshore environments. Mines & Cranes are two other suitable applications for the encoder series.
Mechanically, the MA450 series is based on an 11 mm 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.
