Photoelectric Rotary Encoder A58
Fotoelektrisch Rotary Encoder A58 is a photoelectric incremental encoder series,
which consists of 6 iterations – A58M, A58B, A58C, A58C2, A58C3 and A58D.
These encoders have the same mechanical and electrical properties.
Encoders produce up to 108,000 output pulses per revolution and can, depending on customer requirements,
have different versions of output signals: 11uApp, 1Vpp, TTL or HTL.
