In the field of industrial control correlation photoelectric sensor installation and usage

Correlation of the photoelectric sensor are separate from the transmitters and receivers. Shade between transmitter and receiver if there is no object, emitter light can be receiver receives, switch action, as shown in figure 1 ( 一) As shown in figure. When objects have shelter, receiver transmitter light, produce the output signal of sensor and switch action, as shown in figure 1 ( b） As shown in figure. The photoelectric sensor can distinguish opaque reflective objects, the effective distance. Because the transmitter beam across the induction distance only once, so susceptible to interference, can be reliably used in field or serious dust pollution environment. References: according to the structure of the sensor and the structure of the mounting bracket, to complete the installation, the first to connect the sensor wire according to figure 2 a) Again through the hole, as is shown in the sensor mounting hole and the mounting holes on the mounting bracket alignment, insert the screws and fixed, sensor is fixed on the bracket. Refer to the specific installation method and steps are shown in figure 2.
