B. Working Principle

The Autonics E40H10-2500-3-T-24 works by converting shaft rotation into a series of electrical pulses.

The encoder is mounted onto a compatible rotating shaft. As the shaft rotates, the internal encoder mechanism generates pulse signals corresponding to the movement.

With a resolution of 2500 PPR, the encoder provides 2500 pulse cycles per mechanical revolution on the primary output phase.

Basic Working Sequence

1. The encoder is mounted onto a 10 mm compatible shaft.

2. A 12 to 24 VDC supply is connected.

3. The machine shaft begins rotating.

4. The encoder detects the shaft movement.

5. Electrical pulses are produced through the A and B phases.

6. The Z phase produces a reference or index signal.

7. A PLC, counter, drive, or motion controller receives the pulses.

8. The control system uses these signals to calculate speed, direction, position, distance, or number of revolutions.

Role of A, B and Z Phases

A Phase:
Provides incremental pulse information corresponding to shaft rotation.

B Phase:
Provides another pulse signal shifted relative to A phase. The relationship between A and B helps determine the direction of shaft rotation.

Z Phase:
Provides an index reference signal associated with a complete shaft revolution.

Example

Suppose the E40H10-2500-3-T-24 is installed on a motor shaft.

As the motor rotates, the encoder produces pulse signals. The PLC can count these signals and use them to calculate:

• Motor RPM

• Number of revolutions

• Relative shaft position

• Clockwise or counterclockwise direction

• Machine travel

• Conveyor distance

This converts mechanical movement into information that an automation system can process.

C. Why Is Autonics E40H10-2500-3-T-24 Used?

The Autonics E40H10-2500-3-T-24 2500 PPR encoder is used when accurate rotational feedback is required from a motor, roller, shaft, or other rotating machine component.

Its high resolution makes it useful where a control system needs more detailed information about shaft movement.

Why Is 2500 PPR Useful?

Higher PPR means the encoder produces more pulse information for each revolution.

A 2500 PPR encoder can therefore provide more detailed rotational information than lower resolution models such as 100 PPR, 360 PPR, 500 PPR, or 1000 PPR encoders.

This is useful for applications requiring:

• Precise speed measurement

• Fine position monitoring

• Accurate material length measurement

• Better rotational resolution

• Detailed motion feedback
