introduction
Definition -:

Opto-electronic sensors are the solid state devices used to detect which effect light beams either interrupting the beam or reflecting the beam back to its source.

Principle of Operation-:

Opto-electronic sensors make use of the physical properties of light sensitive materials. sensors change their electrical features based upon the intensity of light striking the receiver.

Introduction
types of opto electronic sensors
Types of Opto-Electronic Sensors
  • Through beam Opto-electronic sensors
  • Retro-Reflective type sensors
  • Diffuse type sensors
  • Fiber optic type sensors
features of optical fiber sensor
FEATURES OF OPTICAL FIBER SENSOR
  • Optical fiber can also be used in applications such as sensing and measurement besides communication.
  • Fibers have been incorporated into optical systems to detect or measure a wide range of quantities including temperature, pressure, acoustic signals, vibration, rotation, strain, electric current, magnetic fields, fluid flow rate, gas concentration and even X-ray.

RECENT DEVELOPMENT
conclusion
Opto-Sensors are quite simple for most applications, and not only communicate with programmable controls, but can increase product quality and manufacturing speed, as well as reduce size and costs.

Thus opto-sensors are going to play a growing and critical role in the modernized industry.
