Photoelectric Rotary Encoder A58HE1
Photoelectric Rotary Encoder A58HE1 for hollow shafts has an external flexible coupling and
is the main feature that distinguishes it from other similar encoders.
It can produce up to 108,000 output pulses per revolution and has
different versions of output signals available: 11 μApp, 1Vpp, TTL or HTL.
