Industrial rotary encoder for position feedback

The Autonics E40S6-500-3-N-24 is an incremental rotary encoder with 500 pulses per revolution. It provides NPN open collector output for integration with PLCs, counters or motion controllers in automation systems.

Ø6 mm shaft with radial cable for panel mounting

A six millimetre shaft fits standard couplings and the radial cable exits the housing for straightforward wiring in cabinets. The unit operates from 12 to 24 VDC with a five percent ripple tolerance and meets IP50 protection against solid particles.

Low starting torque and 300 kHz response

Starting torque is limited to 40 gf·cm (0.00392 N·m) and the encoder tracks speeds up to 5000 rpm. The 300 kHz maximum response frequency supports high-speed positioning without missed counts.

Questions about this item

What is the maximum rotational speed the E40S6-500-3-N-24 can handle before missing pulses?

The encoder allows up to 5000 rpm while maintaining its 500 pulses per revolution output.

How much heat or electrical load does the NPN open-collector output add during continuous operation?

It runs on 12-24 VDC with a maximum 5 % ripple, so power draw stays low and self-heating is minimal.

Which mating connector or cable assembly is required for the radial cable exit?

The unit ships with a radial cable already attached; no separate connector is needed for basic installation.
