What are the factors that affect the mirror angle of headphone sockets?
Number of views:1918 Time: 2023-12-29

The new photoelectric switches in the Shenzhen headphone socket series usually have the function of automatically preventing mutual interference, so there is no need to worry about mutual interference. However, the series of opposed infrared photoelectric switches are located in several groups parallel to each other


When installing nearby, neighboring groups and mutual interference should be prevented. The most effective way to prevent such interference is to cross set the projector and receiver, and also widen the group distance when exceeding the group. Of course, using different frequencies


The model is also a good way. The effective method to prevent mutual interference in series reflective photoelectric switches is to widen the spacing. Dongguan headphone sockets, and the farther the detection distance, the larger the interval should be. The specific interval


It should be determined based on the debugging situation. Of course, models with different operating frequencies can also be used.


Mirror angle influence: When the tested object has luster or encounters a smooth metal surface, the reflectivity is generally high, which has a similar mirror effect. In this case, the angle between the projector and the tested object should be installed,


To prevent misoperation, the optical axis should not be perpendicular to the detected object. Excluding the influence of background objects: When using reflective diffusion projectors and receivers, sometimes the detected object is closer to the background object,


Photoelectric switches or objects with high reflectivity, such as smooth backgrounds, may cause unstable detection of the photoelectric switch. Due to the high demand for electricity in winter, some users prefer to use DC power sockets on their computers


Although it is very convenient to use electric heaters and other appliances plugged into the same multi-purpose socket, there are significant safety hazards. In terms of electric heating, its starting current is very high. If compared to other high-power systems


When the electrical appliances are started at the same time, the contacts and leads of the socket will be unable to withstand the sudden and excessive electrical load, affecting each other and even damaging the electrical appliances themselves, and even causing accidents.


When installing headphone sockets in Shenzhen, the distance between the exposed sockets and the ground should not be less than 1.8 meters; The concealed socket should be no less than 0.3 meters above the ground. To prevent children from getting electric shock, touching with fingers, or inserting metal objects into the hole of the power supply,


Be sure to choose a safety socket with a safety shield; The construction wiring requirements for single-phase two eye sockets are: when the holes are arranged horizontally, they are "left zero and right fire", and when arranged vertically, they are "above fire and below zero"; single-phase


The wiring requirements for a three eye socket are: the grounding hole at the top must be firmly, solidly, and correctly connected to the grounding wire, and must not be disconnected. The remaining two holes of the DC power socket are marked as "left zero and right fire"


When wiring, it is worth noting that the neutral wire and the protective grounding wire should not be wrongly connected or integrated.
