Optical sensors - photoelectric, industrial applications are found in a wide variety of industrial applications.The WTB12-3P1231 is a photoelectric sensor prominently used in industrial applications. A photoelectric sensor generates a light beam, primarily used in detecting the presence of an object and other motion related operations. It is a more sophisticated and efficient solution for object detection as compared to mechanical sensors.

Basically, the WTB12-3P1231 photoelectric sensor consists of an emitter, receiver, amplifier and amplifier control unit. The emitter produces an infrared beam of light, which is made to project forward and towards the receiver module. This emitted beam is modulated by the amplifier whose state is controlled by the amplifier control unit. Generally, there are three predominant types of photoelectric sensors: Retro-reflective, Through Beam, and Diffused.

The Retro-reflective type is used in industrial environments to detect any sort of objects. In this type of photoelectric sensing system, light produced by the emitter bounces back to the receiver from the object detected. This type of photoelectric sensor usually operates on the principle of “break beam” sensing. If any object interrupts this beam, the receiver will sense that interruption and sends a trigger signal to the amplifier indicating the object presence.

The Through Beam type in the WTB12-3P1231 photoelectric sensor is normally used in controlling mechanical movements like lifting arms, conveyors, etc. In this system, the sender and receiver modules are placed on the two ends of the beam, with the target object passing in between them. In the absence of the target object, the beam will remain uninterrupted and the receiver module will not send any trigger signal to the amplifier. However when the target present, the beam will break and the receiver module will generate a trigger signal to the amplifier which then acts as a source and runs the corresponding equipment.

The Diffused type uses light emitted by the emitter and it is diffused or dispersed by the target object, which is then detected by the receiver. Unlike the retro reflective and through beam models, the receiver is placed adjacent to the emitter, with the target object placed between them. The receiver does not need any lens for detection and thus is more reliable and robust compared to the other two.

The WTB12-3P1231 is a photoelectric sensor that is widely used in a number of industrial applications. Its basic principles remain the same, they are suitable for both stationary and mobile object detection. It is capable of detecting objects in extreme weather conditions and features an adjustable sensitivity setting. As a result, it is highly reliable and durable for use in various situations. With its versatile input voltage range and multiple output forms, the WTB12-3P1231 is an ideal choice for a wide range of applications.
