RI=reference zero positionC=cable R=bending radius: fixed R>10mm; movable R>20mmLED=integrated RGB-LED installation control indicator1. The green light is on when the reading head receives 80% of the signal, otherwise the red light is on;2. When the reading head senses the zero position, the green light flashes once.

An optical linear encoder is a precision measurement device that uses optical sensing technology to detect linear motion. It converts the movement of a read head along a glass or metal scale with fine grating lines into electrical signals, allowing control systems to determine accurate position and displacement.
The accuracy depends on several factors, including scale quality, resolution, installation alignment, temperature changes, vibration, and environmental contamination such as dust or oil.
Optical linear encoders generally provide higher resolution and precision, while magnetic linear encoders are more resistant to dust, oil, vibration, and harsh environments. The choice depends on the required accuracy and operating conditions.
