Description Of Gertech GI-S38 Series Incremental Encoder
The Gertech GI-S38 Series Incremental Encoder is a robust, high-precision rotary encoder made to satisfy motion control requirements across a range of industries. This 38 mm encoder’s robust incremental signal output allows for precise location and speed monitoring. Applications requiring dependable performance but with limited installation space are best suited for the GI-S38 encoder.

Incremental encoders generate information about position, angle, and rotation counts. The resolution is defined in the number of lines or pulses per rotation, which the encoder transmits to the control unit for each rotation. The current position can be determined by the control unit by counting these pulses. A reference run can be necessary when switching on the machine.
