Function

One special feature of this incremental rotary encoder is the mechanical versatility of the flange. The rotary encoder has a centering shoulder with a diameter of 42 mm and one with a diameter of 56 mm. In addition to the four M4 holes, the encoder has a servo infeed on the circumference. This allows you to make a slight adjustment to the reference point of the incremental rotary encoder by turning the housing.

The clamping element that grips into the servo infeed ensures that the incremental rotary encoder stays firmly in place without slipping out of adjustment.

The pulse disk is designed in plastic up to 1500 pulses. Beyond that, glass is used.
