Photoelectric switch manufacturers introduce several common types of photoelectric switches

The photoelectric switch manufacturer said that the type of photoelectric switch was relatively single in the past, but in order to meet the needs of more industries and places, it is divided into many different types and its service life has been greatly improved. Its safety and The wrong action has been effectively controlled, and in-depth research has been carried out to solve the wrong action and other problems. Then the following are cost-effective, good-quality, and good photoelectric switch manufacturers. Several common types of photoelectric switches are introduced.

1. Opposite shooting

The through-beam type is configured by a transmitter and a receiver, the light emitted by the transmitter is directed to the receiver, and a closed optical path is formed between the transmitter and the receiver, and the light of the optical path is blocked or attenuated. A form of testing. Photoelectric switch manufacturers claim that this type of detection has a long operating distance, but it requires a transmitter and requires power distribution. It is troublesome in some applications such as small space and inappropriate power distribution.

2. Direct reflection

The photoelectric switch manufacturer claims that it integrates the transmitter and the receiver. The light emitted by the transmitter is directly irradiated on the object to be detected, and the detection is carried out according to the change of the reflected light. It can be said to be a kind of similar to human eyes. The detector has a shorter operating distance than the through-beam type, and only requires single-wire power distribution. The photoelectric switch manufacturer's products are general-purpose detectors.

3. Mirror reflection type

The high temperature resistant photoelectric switch manufacturer claims that this method is to integrate the transmitter and the receiver, the photoelectric switch is opposed to the contra-angle matrix mirror, the light from the transmitter is fed back to the receiver by the mirror, and the photoelectric switch is reflected by the angular matrix. The mirror (polyprism) forms a closed optical path, and the detection is performed by blocking or attenuating the light of the optical path. This type of detection has a shorter working distance than the direct reflection type and longer than the direct reflection type. Photoelectric switch manufacturers claim that it only needs single-wire power distribution, because the adjustment of the optical axis of the reflector is easier than that of the cross-beam type. The reflector is made of a polygonal corner matrix plate or a reflective film of glass-ceramic particles.

Several switches that have been introduced by photoelectric switch manufacturers have a low probability of generating wrong actions and relatively strong versatility. After being detected, they can immediately respond to the intermediate retention link for a very short time, so it can often meet the requirements of high-end places. ; In addition, photoelectric switch manufacturers said that if the steel industry has special requirements for such switches, they can also choose switches in the form of radiation detection.
