Application fit

The Autonics E40S6-1000-3-N-5 is a 1000 pulse-per-revolution incremental rotary encoder with NPN open-collector output. It suits engineers and technicians who need precise angular feedback for motor control, conveyor positioning or test rigs running on a 5 VDC supply. Buyers who require absolute position data or a higher IP rating should look elsewhere.

Thermals noise power

The encoder draws power from a 5 VDC rail with a maximum 5 percent ripple and has a starting torque no greater than 40 gf·cm (0.00392 N·m). Mechanical speed is limited to 5000 rpm while the electrical response reaches 300 kHz, so heat and acoustic signature stay negligible in normal operation.

Accessories impact

The unit ships in a radial cable configuration with an IP50 protection structure and a 6 mm shaft diameter. No mating connector, mounting bracket or configuration software is included, so the installer must provide wiring termination and mechanical coupling separately.

Questions about this item

How do I mount the Ø6 mm shaft encoder and what wiring step is often missed?

Mount the Ø6 mm shaft with a flexible coupling to avoid side loads, connect the radial cable to a 5 VDC ±5 % supply, and remember the NPN open-collector outputs need pull-up resistors on the controller side.

Which part will need replacement first after long service?

The shaft bearings are the wear item; at up to 5000 rpm they typically set the service interval, while the cable and electronics are solid-state.

What limit appears first when the encoder runs continuously at high speed?

The 300 kHz maximum response frequency caps the usable pulse rate, so at 1000 P/R the electrical limit is reached before the 5000 rpm mechanical rating.
