B. Working Principle

The Autonics E50S8-1000-6-L-5 incremental rotary encoder converts rotation of its shaft into a series of electrical pulses.

When the connected motor or rotating mechanism turns, the encoder shaft rotates with it. The internal sensing system generates electrical pulse signals corresponding to the amount and direction of rotation.

With a resolution of 1000 pulses per revolution, the encoder generates 1000 basic pulse cycles for every complete shaft rotation.

The operating sequence can be understood as:

Machine shaft rotates → Encoder shaft rotates → Pulse signals are generated → Line driver output transmits the signals → PLC or controller processes the pulses → Speed, direction or position is calculated

A and B Phase Signals

The A and B phase signals allow the controller to determine both movement and rotational direction.

The controller compares the timing relationship between the A and B phases to determine whether the shaft is rotating clockwise or counterclockwise.

Z Phase Signal

The Z phase provides an index or reference signal during rotation.

This signal can be used for applications that require a reference position or repeatable rotational reference point.

Differential Line Driver Output

The encoder provides complementary signal pairs:

• A and inverse A
• B and inverse B
• Z and inverse Z

A differential line driver output is useful in industrial environments because the receiving controller can compare the complementary signals, helping maintain reliable pulse communication where electrical interference may be present.

C. Why Is the Autonics E50S8-1000-6-L-5 Used?

The E50S8-1000-6-L-5 is used when industrial equipment needs accurate information about the movement of a rotating shaft.

Speed Measurement

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

Typical applications include:

• Motor speed monitoring
• Conveyor speed measurement
• Roller speed monitoring
• Machine spindle monitoring
• Production machinery speed feedback

Position Measurement

By counting encoder pulses, the controller can determine how far a rotating mechanism has moved.

This is useful in machines where accurate relative positioning is required.

Direction Detection

The A and B phase signals allow a compatible controller to determine the direction of rotation.

This makes the encoder suitable for applications involving forward and reverse movement.

Motor Feedback

The encoder can provide rotational feedback from motors and machine shafts to an industrial controller.

Conveyor Monitoring

The encoder can monitor conveyor rollers or drive shafts to determine conveyor speed and movement.

Length Measurement

When the encoder is mechanically connected to a measuring wheel or roller, rotational pulses can be converted into linear distance.

This principle can be used for measuring materials such as:

• Sheet material
• Wire
• Cable
• Paper
• Film
• Fabric
• Packaging material

Machine Synchronization

Encoder signals can help synchronize different rotating sections of an automated machine.

Production Counting

Encoder pulses can also be used as part of automated counting, indexing, and repetitive machine operations.
