Industrial Position Feedback

The Autonics E40H12-1000-3-N-24 is an incremental rotary encoder built for industrial motion control. It delivers 1000 pulses per revolution through an NPN open collector output. The unit suits automation engineers integrating precise position or speed feedback into PLC or counter systems.

Wiring And Voltage Check

Verify that the control system accepts NPN open collector signals before installation. Confirm the supply voltage sits within 12 to 24 VDC with ripple under 5 percent. Ensure the controller input can handle a maximum response frequency of 300 kHz for accurate pulse capture.

Mechanical Integration

The encoder mounts via a hollow shaft with a 12 mm inner diameter and uses a radial cable connection for wiring access. It operates up to 5000 rpm with a starting torque below 50 gf.cm. The IP50 rated housing protects internal optics from dust in enclosed cabinet environments.

Questions about this item

What comes in the box and what must I supply separately?

The box contains one Autonics E40H12-1000-3-N-24 rotary encoder with a radial cable. You must provide a 12-24VDC power supply within ±5% ripple and a mounting arrangement for the Ø12 mm shaft.

How do I choose between the available versions or capacities?

This specific model is fixed at 1000 pulses per revolution with NPN open-collector output and IP50 protection. Other resolutions, output types or protection ratings would be different part numbers.

What does the 300 kHz maximum response frequency mean once the encoder is installed?

It allows reliable pulse counting up to 5000 rpm at the full 1000 P/R resolution, so the connected controller receives clean position data throughout the rated speed range.
