The A58 series is a photoelectric incremental encoder series that is a comprised of 6 iterations – A58M, A58B, A58C, A58C2, A58C3 and A58D. These encoders share the same mechanical and electrical characteristics but differ in mounting options. Encoders produce up to 108.000 output pulses per revolution and depending on customer demands can have different versions of output signals: 11 uApp, 1Vpp, TTL ot HTL.
