Autonics E40S8 Incremental Encoder

The Autonics E40S8-1024-3-T-24 is an incremental rotary encoder built for motion feedback in industrial automation. It delivers 1024 pulses per revolution through a totem-pole output stage and accepts a 12-24VDC supply. The Ø8mm shaft and radial cable suit panel-mounted installations where space is limited.

Upgrade From Lower Resolution Sensors

Replacing a lower-count encoder with this 1024 P/R unit improves positional granularity for servo loops and cut-to-length systems. The jump is worthwhile when the controller can process 300kHz signal frequency and the mechanical load stays within 5000rpm. Existing wiring for 12-24VDC totem-pole interfaces can usually remain unchanged.

Integration Requirements And Freedoms

The encoder needs a stable 12-24VDC rail with no more than 5% ripple and a controller input rated for totem-pole levels. Its 40gf.cm starting torque keeps motor loading low, while the IP50 housing resists dust ingress in cabinet environments. The radial cable exit clears rear-panel depth constraints, freeing layout options for tight enclosures.

Questions about this item

What shaft diameter fits the Ø8 mm encoder shaft?

The encoder uses an 8 mm diameter shaft, so couplings or gears must match that size.

How do I wire the radial cable without damaging the 300 kHz signal?

Keep the cable away from high-current lines, use shielded twisted pairs, and secure the strain relief so the cable cannot flex at the encoder body.

When should I plan to replace the unit given the 5000 rpm rating?

At continuous 5000 rpm the bearings reach their design life sooner; schedule inspection every 12 months and replace if starting torque exceeds 40 gf·cm.
