Incremental rotary encoder with NPN output

The Autonics E40H8-360-3-N-24 is an incremental rotary encoder that delivers 360 pulses per revolution. It uses an NPN open-collector output stage and operates from a 12-24VDC supply. The unit mounts via an 8 mm shaft and connects through a radial cable.

Suited for position feedback in motor control

This encoder suits applications that need 360 P/R resolution and a 300kHz maximum response frequency. It is not for systems that require absolute positioning data, higher pulse counts per turn, or push-pull and line-driver output types.

Key selection specification is the 360 P/R

The 360 pulses per revolution defines the angular granularity available to the controller. Verify that this resolution matches the motion profile and feedback loop requirements before specifying the part.

Questions about this item

What power supply voltage do I need to run the E40H8-360-3-N-24?

The encoder operates from a 12-24 VDC supply with a ±5 % tolerance and ripple of 5 % peak-to-peak.

Will the 300 kHz maximum response frequency work with my existing 5000 rpm motor shaft?

At 5000 rpm the output frequency reaches 30 kHz for 360 P/R, well within the 300 kHz limit.

How can I verify the NPN open-collector output is switching correctly after wiring?

Measure the output with a multimeter or oscilloscope; it should pull low on each pulse and float high through your pull-up resistor.
