Autonics incremental rotary encoder

The Autonics E40S8-1000-3-T-24 is an incremental rotary encoder built for motion-control tasks that require precise position feedback. It suits electricians, automation technicians and machine builders who need a compact sensor with a solid shaft for direct coupling to motors or gearboxes.

Radial cable and NPN totem-pole output

The unit ships with a radial cable connection that simplifies wiring in tight cabinets and a totem-pole control output compatible with standard NPN inputs on PLCs and counters. No additional interface modules or signal conditioners are required for basic integration.

1000 pulses per revolution resolution

A resolution of 1000 P/R defines the smallest angular step the encoder can report, directly determining the positioning granularity of the connected system. Verify that this pulse count matches the motion profile and controller scaling before purchase.

Questions about this item

Will the Ø8 mm shaft or internal bearings need periodic replacement?

Starting torque is rated at max 40 gf·cm (0.00392 N·m), indicating low friction; the IP50 rating protects against dust ingress that could accelerate bearing wear.

Which specification caps continuous operation first — the 5000 rpm mechanical limit or the 300 kHz electrical response?

The 5000 rpm maximum allowable revolution is the hard mechanical ceiling; at 1000 P/R the electrical response supports higher speeds, so the rpm rating is reached first.

How much heat or noise does the encoder generate when powered at 24 VDC all day?

Power draw stays within the 12–24 VDC ±5 % supply range with max 5 % ripple; low starting torque and IP50 enclosure keep audible noise and temperature rise minimal.
