Rotary Encoders measure the number of rotations, the rotational angle, and the rotational position.
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
Compact Encoder with External Diameter of 25 mm
E6B2-C
Incremental 40-mm-dia. Rotary Encoder
General-purpose Encoder with External Diameter of 40 mm
E6C2-C
General-purpose Encoder with External Diameter of 50 mm
E6C3-C
Rugged Incremental 50-mm-dia. Rotary Encoder
E6D-C
High-resolution Encoder with Diameter of 55 mm
E6F-C
Incremental 60-mm-dia. Rotary Encoder
E6H-C
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
General-purpose Absolute Encoder with External Diameter of 50 mm
E6C3-A
Rugged Rotary Encoder
Slim Encoder with Diameter of 50 mm
E6F-A
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.
