Rotary encoder incremental NPN

The Autonics E50S8-400-3-N-24 is an incremental rotary encoder with NPN open-collector output. It delivers 400 pulses per revolution and operates from a 12-24 VDC supply with a maximum response frequency of 300 kHz. The unit has an Ø8 mm shaft, axial cable connection and an IP50 protection rating.

Suited for position feedback in automation

This encoder suits applications that require a solid-shaft incremental sensor with NPN signalling and standard environmental protection. It is not intended for buyers who need a push-pull or line-driver output, a hollow-shaft design, or a higher environmental rating than IP50.

Resolution 400 pulses per revolution

The 400 P/R resolution defines the angular granularity available to the controller. With a maximum allowable speed of 5000 rpm and a 300 kHz response limit, the encoder meets the timing needs of typical servo and stepper feedback loops.

Questions about this item

What shaft diameter does the E50S8-400-3-N-24 encoder need for mounting?

The encoder fits an Ø8 mm shaft, so the mating shaft must match that diameter.

How is the axial cable connected and what wiring mistake should be avoided?

The encoder uses an axial cable for power and signal; connect the NPN open-collector outputs to a pull-up resistor and verify the 12-24 VDC supply polarity before powering on.

What maintenance will the E50S8-400-3-N-24 require over time?

With IP50 protection the unit is not sealed against dust or water, so plan periodic cleaning of the shaft seal area and inspect the cable for wear; the mechanical design is rated for up to 5000 rpm operation.
