Incremental rotary encoder

The Autonics E40S8-200-3-N-24 is an incremental rotary encoder that delivers 200 pulses per revolution through an NPN open collector output. It operates on a 12-24VDC supply and connects via a radial cable. The unit has an IP50 protection rating and a Ø8 mm shaft. It is suited for position feedback in automation and motion-control systems.

Suitable for 300 kHz response

This encoder fits applications that require a maximum response frequency of 300kHz and a maximum allowable revolution of 5000rpm. Starting torque is limited to 40gf.cm. It is not intended for environments that demand higher ingress protection than IP50 or for systems that require a different output type such as PNP or line driver.

Resolution fixed at 200 pulses per revolution

The single specification that determines compatibility is the resolution of 200P/R. If the control system expects a different pulse count per turn, this encoder will not match the required positional granularity.

Questions about this item

Does the Autonics E40S8-200-3-N-24 ship with any mounting hardware or cables beyond the radial cable already fitted?

The unit is supplied as a single encoder with its radial cable attached; mounting brackets, couplings or additional connectors are not included and must be sourced separately.

How do I decide between the 200 P/R resolution and other pulse counts for my application?

Choose 200 pulses per revolution when you need a balance of positional granularity and the 300 kHz maximum response frequency; higher resolutions reduce the usable speed range while lower counts give coarser position data.

What does the 300 kHz maximum response frequency mean once the encoder is installed on a motor shaft?

It allows reliable pulse counting up to 5000 rpm at the rated 200 P/R resolution; exceeding either the frequency or the mechanical speed limit can cause missed counts or signal errors.
