MA420 Redundant Encoder
Redundant encoder for positioning purposes. The MA420 series is a range of encoders that supports combinations. One of two incremental encoders integrated into one housing. The other option is the integration of an incremental and an absolute encoder, supporting communication protocols such as SSI, PROFIBUS, or CAN. Additional incremental signals can also be provided with TTL or HTL output levels on the absolute encoder. The redundancy makes the MA420 suitable for use in safety-critical applications.
Characteristics MA420 Redundant Encoder
The extremely robust design and encapsulation of the encoder series enable use in marine or offshore environments. Mines & Cranes are two other suitable applications for the series.
Mechanically, the MA420 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.
