WL12GC-3P2472A91

Optical Sensors are generally classified into Photoelectric, Industrial, and Infrared sensors. WL12GC-3P2472A91 falls into the category of Industrial and Photoelectric Sensors, and its application field and working principle are as follows:

Application Field

WL12GC-3P2472A91 sensors are designed for teaching, transporting and protecting robots, with the ability to detect and identify objects in a certain range. As an Industrial Sensor, it is mainly used in industrial automation applications such as robotic vision, process control, and robotic hand-eye coordination. In Photoelectric Sensor applications, WL12GC-3P2472A91 can be used in image processing and Bar Code recognition.

Working Principle

WL12GC-3P2472A91 works on a passive beam principle, with two reflectors reflecting a beam of light from a light source. The light source is a LED light transmitter, and the reflectors can be invisible or visible white built-in markers. The two markers are on a transmitting module and the receiving module, and when a robot is nearby, the beam of light from the transmitter is broken and the receiving module will detect the break. The receiving module then communicates with the robot to indicate the presence of an obstacle.

When a robot approaches, it will activate the built-in markers on the receiving module and the transmitter will send out a beam of light to detect the presence of an obstacle. The robot will then use the output signal from the WL12GC-3P2472A91 to determine the position and movement of its own parts. This detection system helps ensure that the robot does not get too close to the obstacle.

In addition to the application field and working principle, WL12GC-3P2472A91 also offers high accuracy and repeatability of the detection signal. It has a detection range of 0.7 to 1.5m and a sampling frequency of up to 2000Hz. This sensor offers both optical and digital outputs, making it suitable for a wide range of industrial and photoelectric applications.
