Autonics E30S4-1024-6-L-5 Incremental Rotary Encoder

The E30S series incremental rotary encoders feature compact Ø30 mm size housings for easy installation in tight or limited spaces. The low moment of inertia of the shaft minimizes the effect on the rotation of applied equipment. The encoders are available in various control output options.
