A. Product Overview

The Autonics E50S8-30-3-T-1 30 PPR Incremental Rotary Encoder converts mechanical shaft rotation into electrical pulse signals that can be processed by PLCs, counters, controllers and industrial automation systems.

The encoder has a 50 mm body size and 8 mm shaft, making it suitable for various industrial machine applications. Its 30 PPR resolution means that the encoder generates 30 pulses for each complete shaft revolution.

The model provides A, B and Z phase outputs, allowing compatible control systems to monitor rotational movement, determine direction and establish a reference position.

B. Working Principle

The Autonics E50S8-30-3-T-1 incremental encoder works by converting shaft rotation into a series of electrical pulses.

The encoder shaft is mechanically connected to a rotating machine component such as:

• Motor shaft

• Conveyor roller

• Measuring wheel

• Machine spindle

• Drive shaft

When the shaft rotates, the encoder generates pulses through its output channels.

Because this model has a resolution of 30 PPR, it produces 30 basic pulses during one complete shaft revolution.

A compatible PLC, counter or controller can count these pulses to determine movement or rotational speed.

A Phase and B Phase

The encoder provides A and B phase signals.

These signals are electrically shifted from each other. A compatible controller can compare the two phases to determine the direction of rotation.

This allows detection of:

• Clockwise rotation

• Counterclockwise rotation

Z Phase

The Z phase provides an index signal associated with a complete revolution.

It can be used as a reference position in suitable positioning and machine control applications.

30 PPR Resolution

With 30 pulses per complete revolution:

360 degrees divided by 30 equals 12 degrees per basic pulse

This makes the encoder suitable for applications where moderate rotational resolution is sufficient.

C. Why Is the Autonics E50S8-30-3-T-1 Used?

1. RPM Measurement

The pulse frequency generated by the encoder can be used to calculate rotational speed in rpm.

2. Motor Speed Monitoring

The encoder can provide feedback from a rotating motor shaft to a PLC or speed monitoring system.

3. Rotation Detection

It can confirm whether a machine shaft or roller is rotating.

4. Direction Detection

The A and B phases allow compatible controllers to determine clockwise or counterclockwise movement.

5. Position Measurement

Pulse counting can be used to calculate relative rotational position.

6. Conveyor Speed Monitoring

The encoder can be connected to a conveyor roller for speed and movement measurement.

7. Length Measurement

When connected to a correctly sized measuring wheel, encoder pulses can be converted into linear distance.

This is useful for:

• Cable measurement

• Paper measurement

• Film measurement

• Textile measurement

• Sheet length measurement

• Packaging material measurement

8. PLC Automation

The encoder can provide pulse feedback to a compatible PLC high speed counter input.

9. Machine Synchronization

Encoder feedback can help coordinate movement between rollers, conveyors and other machine mechanisms.

10. Production Monitoring

Rotational information can be used for machine cycle monitoring, movement verification and production control.
