Rotary encoder for industrial positioning

The Autonics E40HB8-1024-3-T-24 is an incremental rotary encoder built for motion-control systems that need precise position feedback. It delivers 1024 pulses per revolution and operates on a 12-24 VDC supply with a ±5% tolerance. Engineers specifying automation equipment will find it suited to conveyor, packaging or servo applications where reliable digital quadrature signals are required. The totem-pole output drives standard PLC or counter inputs directly.

Radial cable and IP50 housing for panel mounting

The unit measures 40 mm in body diameter and fits an 8 mm shaft, allowing direct coupling to motor or gearbox shafts without additional adapters. A radial cable exit routes wiring cleanly along the mounting surface, reducing snag risk in tight cabinets. The IP50 rating protects internal optics from dust ingress while the low starting torque of 50 gf.cm minimises load on small drive shafts. The red finish aids visual identification during maintenance.

Rated for 5000 rpm and 300 kHz response

Maximum allowable speed reaches 5000 rpm while the electronics maintain a 300 kHz response frequency, ensuring accurate pulse capture at high velocities. Power draw stays within the 12-24 VDC ±5% range with ripple limited to 5% peak-to-peak, so a standard industrial supply is sufficient. The totem-pole driver operates without external pull-up resistors, simplifying wiring and reducing component count in the control cabinet.

Questions about this item

How does the 12-24 VDC supply affect the totem-pole output voltage swing?

The totem-pole output follows the supply rail, so at 12 VDC the high level is near 12 V and at 24 VDC it is near 24 V, with a 5 % ripple tolerance.

What shaft diameter and mounting clearance does the Ø8 mm hollow bore need?

The encoder fits an 8 mm motor shaft; allow enough axial space for the radial cable exit and keep the mounting surface flat so the IP50 seal is not compromised.

Which wiring step is most often missed when connecting the radial cable?

Installers frequently forget to tie the shield to ground at the controller end, which is essential for noise immunity at the 300 kHz response frequency.
