High-Precision Optical Encoders for Industrial Automation

An optical encoder is a high-accuracy position and speed sensing device used in industrial automation, CNC machines, elevators, robotics, and motion control systems. By using optical discs and light sensors, optical encoders convert mechanical movement into precise electrical signals for reliable feedback and control.

ISC Global is a trusted optical encoder supplier in India, offering genuine, high-performance solutions from leading global manufacturers like Elcis. As an authorized dealer, we ensure accuracy, durability, and dependable after-sales support.

 

What Is an Optical Encoder?

An optical encoder uses a light source, code disc, and photo sensors to detect rotational or linear movement. When the disc rotates, light passes through or is blocked by patterned slots, generating electrical pulses that represent position, speed, or direction.

Compared to magnetic encoders, optical encoders provide higher resolution and precision, making them ideal for applications where accuracy is critical.
