From high-speed manufacturing to medical imaging and mobile devices, optical position sensors play a critical role in capturing movement, position, and alignment with remarkable accuracy. These sensors offer a non-contact method to detect the position or displacement of objects using light—paving the way for more intelligent and responsive systems.

What is an Optical Position Sensor?
An optical position sensor detects the position, displacement, or motion of an object using light. It typically works by emitting light—either through LEDs or lasers—and then analyzing the reflected or interrupted light to determine position or movement.

There are several types of optical position sensors, including:

Photodiodes

Charge-Coupled Devices (CCD)

Complementary Metal-Oxide-Semiconductor (CMOS) sensors

Linear and rotary encoders

These sensors are known for their high resolution, fast response times, and reliability in various environmental conditions.

Key Applications
