The Model ZSD encoder is ideal for applications requiring a miniature, high
precision, low cost encoder, designed with all metal construction for years of
The NPN Open Collector outputs are each current limited to 20 mA. The outputs are standard quadrature with index, available in resolutions up to 2500 pulses per shaft revolution.
The quadrature separation is typically 90 electrical degrees. Output A leads output B for clockwise rotation of the encoder shaft.
