Rotary Encoders measure the number of rotations, the rotational angle, and the rotational position.

Rotary Encoder Omron

Incremental

Incremental Encoders output a pulse string according to the rotational displacement of an axis. The number of rotations can be detected by counting the number of pulses.

E6A2-C Omron

E6A2-C

Incremental 25-mm-dia. Rotary Encoder

Compact Encoder with External Diameter of 25 mm

E6B2-C Omron

E6B2-C

Incremental 40-mm-dia. Rotary Encoder

General-purpose Encoder with External Diameter of 40 mm

E6C2-C Omron

E6C2-C

Slim Incremental 50-mm-dia. Rotary Encoder

General-purpose Encoder with External Diameter of 50 mm

E6C3-C Omron

E6C3-C

Rugged Rotary Encoder

Rugged Incremental 50-mm-dia. Rotary Encoder

E6D-C Omron

E6D-C

High-resolution Encoder

High-resolution Encoder with Diameter of 55 mm

E6F-C Omron

E6F-C

Rugged Rotary Encoder

Incremental 60-mm-dia. Rotary Encoder

E6H-C Omron

E6H-C

Hollow-shaft Encoder

Hollow-shaft Encoder with Diameter of 40 mm

Absolute

Absolute Encoders output the rotational angle using an absolute code. The rotational position can be detected by reading the code. This eliminates the need to return to the origin at startup.

E6CP-A Omron

E6CP-A

Low-cost Encoder

General-purpose Absolute Encoder with External Diameter of 50 mm

E6C3-A Omron

E6C3-A

Rugged Rotary Encoder

Slim Encoder with Diameter of 50 mm

E6F-A Omron

E6F-A

Rugged Rotary Encoder

Absolute 60-mm-dia. Rotary Encoder

Direct Discrimination Unit

A Direction Discrimination Unit accepts phase difference signal from the Encoder to detect the direction of rotation. Either voltage or open-collector outputs can be connected.

E63-WF Omron

E63-WF

Direct Discrimination Unit

Detects the Rotary Encoder Direction
