Incremental rotary encoder for position feedback

The Autonics E40H8-1000-3-N-24 is an incremental rotary encoder that delivers 1000 pulses per revolution. It uses an NPN open-collector output and operates on a 12-24VDC supply with a 5 percent ripple tolerance. The unit has a Ø8mm shaft inner diameter and a radial cable connection. Its protection rating is IP50.

Suitable users and limitations

This encoder suits applications that require 1000P/R resolution and a maximum response frequency of 300kHz. It supports speeds up to 5000rpm with a starting torque of max 50gf.cm. Buyers who need a higher resolution or an absolute output type should look at other models. Installations requiring a protection rating above IP50 or an axial cable exit will need a different unit.

Deciding specification: 1000P/R resolution

The 1000P/R resolution is the primary figure that determines whether this encoder matches the motion-control requirements. Verify that the controller can accept NPN open-collector signals at the required frequency. Confirm the 12-24VDC supply range and IP50 rating fit the operating environment.

Questions about this item

Should I choose the 1000 P/R version or a different resolution for my application?

The 1000 P/R resolution provides 1000 pulses per revolution; select a different resolution only if your controller requires a higher or lower count per turn.

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

It limits the usable shaft speed to about 5000 rpm at 1000 P/R; exceeding this speed causes missed pulses and position errors.

How does the NPN open collector output affect wiring and voltage levels?

The NPN output pulls the signal low to ground; connect a pull-up resistor to the 12-24 VDC supply so the high level follows the supply voltage.
