Industrial rotary encoder for position feedback

The Autonics E50S8-2500-3-N-24 is an incremental rotary encoder that delivers 2500 pulses per revolution for precise position and speed feedback. It operates on a 12-24VDC supply with a 5% tolerance and uses an NPN open collector output suitable for industrial control inputs. The unit is rated IP50 for dust protection and connects via an axial cable.

Suited for motion-control systems needing NPN

Engineers building servo drives, conveyor controls or CNC axis feedback will find the 300kHz maximum response frequency and 5000rpm mechanical limit compatible with high-speed applications. The 8mm shaft diameter fits standard couplings. Buyers who require absolute positioning data, a hollow-shaft format, higher environmental sealing or a different output protocol should look at other encoder types.

Axial cable simplifies panel wiring

The fixed axial cable exits the encoder body parallel to the shaft, reducing the clearance needed behind the mounting surface and easing cable routing in tight cabinets. NPN open collector output allows direct connection to PLC inputs without extra interface modules. No configuration software or programming accessories are included; the device is ready for installation once wired to the control system.

Questions about this item

Does my controller need an NPN-compatible input to read the encoder's open-collector output?

Yes, the encoder uses an NPN open-collector output, so the receiving device must accept sinking signals from a 12-24VDC supply.

Will the 8 mm shaft fit the motor coupling I already use on my existing 5000 rpm drive?

The encoder shaft is Ø8 mm and rated for 5000 rpm maximum, matching many standard couplings for that speed range.

How can I confirm the 2500 pulses per revolution are being counted correctly after wiring?

Rotate the shaft at a known speed and verify the controller registers 2500 pulses per turn up to the 300 kHz response limit.
