Rotary encoder for precision positioning

The Autonics E50S8-2500-3-V-5 is an incremental rotary encoder delivering 2500 pulses per revolution. It operates on a 5 VDC supply with a ±5 % tolerance and provides a voltage control output. The Ø8 mm shaft suits motion-control tasks that require accurate angular feedback.

Thermal and electrical behaviour in normal use

Maximum response frequency reaches 300 kHz while the shaft can spin up to 5000 rpm. Starting torque is limited to 70 gf·cm (0.00686 N·m), keeping mechanical drag low. The IP50 housing protects internal optics from dust ingress during continuous operation.

Axial cable and warranty coverage

An axial cable connection simplifies wiring in tight enclosures by routing the leads parallel to the shaft axis. The unit ships as a single piece in a box and carries a three-year parts warranty with one year of labour coverage. Buyers needing a hollow-shaft or absolute-output encoder should consider other models.

Questions about this item

How do I mount the E50S8-2500-3-V-5 encoder with its Ø8 mm shaft and axial cable?

Slide the Ø8 mm shaft into the mating bore, secure with a coupling or set screw, then route the axial cable away from moving parts; the step often missed is checking shaft alignment to avoid excess starting torque.

What maintenance will the E50S8-2500-3-V-5 need over time?

Inspect the axial cable for wear and verify the IP50 seal remains intact; the bearing preload is rated for a maximum starting torque of 70 gf·cm (0.00686 N·m), so replace the unit if torque rises above that value.

At what speed does the 2500 P/R resolution hit its electrical limit on this encoder?

The maximum response frequency is 300 kHz, which corresponds to 5000 rpm at 2500 pulses per revolution; sustained operation beyond that speed will lose counts first.
