B. Working Principle

The Autonics E40S6 incremental rotary encoder converts shaft rotation into electrical pulses.

The encoder shaft is mechanically connected to the rotating part of a machine, motor, roller or other equipment.

When the shaft rotates, the encoder generates a sequence of electrical pulses.

The receiving controller counts these pulses to determine how much the shaft has rotated.

Resolution and PPR

PPR means Pulses Per Revolution.

The number indicates how many pulses are generated during one complete revolution of the encoder shaft.

60 PPR Encoder

The E40S6-60-3-T-24 generates 60 pulses per revolution.

One basic pulse represents:

360 degrees divided by 60 equals 6 degrees

This model is suitable when moderate resolution is sufficient.

400 PPR Encoder

The E40S6-400-3-T-24 generates 400 pulses per revolution.

One basic pulse represents:

360 degrees divided by 400 equals 0.9 degrees

The 400 PPR model therefore provides finer rotational measurement than the 60 PPR model.

A and B Phase Operation

The A and B output phases are shifted relative to each other.

By monitoring which phase changes first, a compatible controller can determine the direction of shaft rotation.

This allows the system to distinguish between:

• Clockwise rotation

• Counterclockwise rotation

Z Phase Operation

The Z phase provides an index pulse associated with each complete revolution.

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

C. Why Is the Autonics E40S6 Series Used?

1. Speed Measurement

The pulse frequency generated by the encoder can be used to calculate shaft or motor speed.

2. RPM Monitoring

The encoder can provide pulse feedback to a PLC, tachometer or controller for RPM measurement.

3. Position Measurement

By counting pulses, the control system can determine how far a rotating shaft has moved.

4. Rotation Direction Detection

The A and B phases allow compatible equipment to determine whether the shaft is rotating clockwise or counterclockwise.

5. Conveyor Monitoring

The encoder can be connected to a conveyor roller to measure conveyor movement, distance or speed.

6. Motor Feedback

It can provide rotational feedback from motors and machine shafts to automation systems.

7. Length Measurement

When connected to a measuring wheel or roller, rotary encoder pulses can be converted into linear distance.

This is useful in applications involving:

• Film

• Paper

• Cable

• Textile

• Sheet material

• Packaging material

8. Product Positioning

Pulse counting can be used to determine machine or product position in automated equipment.

9. PLC Integration

The pulse outputs can be connected to compatible high speed PLC inputs or counter modules.

10. Machine Synchronization

Encoder feedback can help synchronize rollers, conveyors, feeders and other moving machine components.

11. Production Monitoring

Rotation and pulse information can be used for machine cycle monitoring, length measurement and production control.

12. Compact Installation

The 40 mm encoder housing is suitable for machinery where installation space is limited.
