Encoder

Very compact design encoder was made possible by designing in one body with the motor.

Magnetic encoder

Magnetic sensor detects the change of magnetic density and converts into output signals.

Optical encoder

Consists of a high precision code wheel with reflection/no refection area patterns, and one-package sensor that includes emitter and detector. Output signals are generated according to motor rotation.

An encoder is a device that "encodes".
An encoder is a device or software that converts information into data code under a fixed rule and records or converts data written in one format to another format. This process is called 'encoding'. Examples include conversion pictorial image or moving image, and data compaction or encryption.
A motor encoder detects speed, position or angle of rotation and converts the information into digital signals, which helps with accurate positioning and speed control.
Namiki has 2 types of encoders, magnetic and optical, depending on the dynamic principles.
