Incremental rotary encoder with NPN output

The Autonics E40H8-800-3-N-24 is an incremental rotary encoder that delivers 800 pulses per revolution through an NPN open-collector output. It operates on a 12-24VDC supply with a maximum response frequency of 300kHz and a top speed of 5000rpm. The Ø8mm shaft connects via a radial cable and the housing meets IP50 protection.

Suited for position feedback in motion systems

This encoder fits applications needing incremental position or speed feedback with NPN logic, such as conveyor drives, packaging equipment or motor control loops. It is not suitable for designs that require absolute position data, push-pull or line-driver outputs, or a higher ingress-protection rating than IP50.

800 pulses per revolution resolution

The fixed resolution of 800P/R determines the smallest angular step the encoder can report and directly sets the positioning granularity of the control system. Verify that this count matches the controller’s input scaling before purchase.

Questions about this item

Will the 8mm shaft fit the motor coupling I already use on older equipment?

The encoder shaft inner diameter is Ø8mm, so it matches any coupling or hub bored for an 8mm shaft.

How can I verify the encoder is sending clean pulses after wiring it up?

At up to 5000rpm the unit produces 800 pulses per revolution with a maximum response frequency of 300kHz; an oscilloscope should show a stable square wave at that rate.

Does the box include a mating connector or do I need to source one separately?

The encoder comes with a radial cable already attached; no separate connector is required for the NPN open-collector output.
