A. Product Overview

The Autonics E80H30-1024-3-T-24 is an 80 mm diameter incremental rotary encoder with a 30 mm hollow shaft.

It generates electrical pulse signals as the connected shaft rotates. These pulses can be received by PLCs, counters, motion controllers, drives, and other industrial control equipment to determine rotational movement.

The model provides 1024 pulses per revolution, allowing relatively precise monitoring of rotational position and speed.

B. Working Principle

The Autonics E80H30-1024-3-T-24 works by converting mechanical shaft rotation into electrical pulse signals.

The encoder is mounted directly around a rotating motor or machine shaft.

As the shaft rotates, the encoder produces a defined number of electrical pulses.

Because this model has a resolution of 1024 PPR, one complete mechanical revolution generates 1024 pulse cycles on the primary output channel.

The basic working process is:

1. The encoder is installed directly on the rotating shaft.

2. The shaft begins rotating.

3. The internal encoder mechanism detects rotational movement.

4. Electrical pulse signals are generated.

5. A and B phase signals provide rotational pulse information.

6. The phase relationship between A and B allows the control system to determine rotation direction.

7. The Z phase provides a reference pulse associated with a complete revolution.

8. A PLC, counter, motion controller, or drive processes these signals.

9. The system calculates parameters such as speed, direction, position, or rotational distance.

Example

Suppose the encoder is installed on a motor shaft.

If the motor completes one full revolution, the encoder generates 1024 PPR output signals.

A PLC can count these pulses to calculate:

• Motor speed

• Number of revolutions

• Shaft position

• Rotational direction

• Travel distance when mechanically linked to a roller or conveyor

This allows the control system to monitor machine movement accurately.

C. Why Is Autonics E80H30-1024-3-T-24 Used?

The Autonics E80H30-1024-3-T-24 hollow shaft encoder is used when an industrial machine requires feedback about rotating movement.

Unlike a simple proximity sensor that may only detect the presence of an object, an incremental rotary encoder continuously generates pulses as the shaft rotates.

These pulses allow the automation system to measure movement more precisely.

Main Parameters It Can Help Measure

• Rotational speed

• Shaft position

• Rotation direction

• Number of revolutions

• Angular movement

• Machine movement

• Conveyor travel

• Linear distance when mechanically converted from rotary motion

Common Applications

• Electric motors

• Conveyor systems

• Industrial machinery

• Packaging machines

• Rolling machines

• Winding machines

• Unwinding machines

• Industrial automation systems

• PLC based machine control

• Factory automation equipment

Why Use a Hollow Shaft Encoder?

A major advantage of the E80H30 series is its hollow shaft construction.

The encoder can be mounted directly onto the rotating shaft.

This can eliminate the need for a separate flexible coupling between the machine shaft and encoder shaft.

Potential advantages include:

• Easier mechanical installation

• Compact mounting

• Reduced coupling components

• Direct rotational feedback

• Better integration with motor shafts

• Simplified machine design
