E40H Autonics Encoder

The Autonics E40H Series is a compact Ø40 mm hollow shaft incremental rotary encoder engineered for precise motion detection and position feedback in industrial automation systems. Its hollow shaft design enables quick installation in space-constrained environments while minimizing shaft inertia for smoother machine operation. With multiple pulse resolutions, output options, and power supply configurations, the E40H Series is ideal for applications such as conveyors, packaging equipment, CNC machines, robotics, and factory automation systems.
