In the process of using headphone socket, there will be interference. How can we avoid the interference of headphone socket? Here's a good introduction to this problem.

Novel photoelectric switches of headphone socket series usually have the function of automatically preventing mutual interference, so there is no need to worry about mutual interference. However, when the series of counter-fired infrared photoelectric switches are installed side by side, the adjacent groups and mutual interference should be prevented. The most effective way to prevent this kind of interference is to set the projector and receiver crosswise, and to open the group spacing when exceeding the group. Of course, using different frequencies of the machine is also a good way.

The effective way to prevent mutual interference of series reflective photoelectric switches is to open the interval. Headphone socket and the farther the detection distance is, the greater the interval should be. The specific interval should be determined according to the debugging situation. Of course, different types of machines with different working frequencies can also be used.

Mirror angle effect: When the measured object is glossy or encounters a smooth metal surface, its reflectivity is generally very high, and it has the function of approximating the mirror surface. At this time, the angle between the projector and the detected object should be installed so that its optical axis is not perpendicular to the detected object, so as to prevent misoperation.

Exclude the influence of background: When using reflective diffuse projector and receiver, sometimes the photoelectric switch may not be able to detect stably because the detected object is close to the background, the photoelectric switch or the background is smooth and other objects with high reflectivity.

DC power socket has a large demand for electricity in winter. Some users like to plug computers and heating into the same multi-purpose socket. Although it is very convenient to use, it has a great potential safety hazard. In the case of electric heating, its starting current is very large. If it starts at the same time with other high-power electrical appliances, the contacts and leads of sockets will be difficult to withstand the sudden excessive electric load, which will affect each other, even destroy the electrical appliances themselves, and even cause accidents.

When sockets are installed, open sockets should be no less than 1.8 meters from the ground; concealed sockets should be no less than 0.3 meters from the ground. In order to prevent children from electric shock, finger touch or metal plugging into the hole of power supply, safe sockets with safety shield must be selected; the construction wiring requirements of single-phase two-eye sockets are: when the hole is arranged horizontally, it should be "left zero fire" and "up fire down zero" when it is arranged vertically. The wiring requirement of single-phase three-eye socket is that the top grounding hole must be firmly connected with the grounding wire, solidly connected, and must not be disconnected. The remaining two holes of DC power outlet are connected according to the rule of "left zero right fire". It is noteworthy that the zero line and the protective grounding line should not be staggered or connected as one. Refrigerators should use independent three-eye sockets with protective grounding.

Earphone socket manufacturers are well known that the socket can only withstand 2500W power, but the frequent or simultaneous use of high-power electrical appliances such as home computers and electric heating will exceed the safe carrying range of the current of ordinary sockets, which can easily lead to power failure or even fire accidents.

Therefore, high-power appliances must be equipped with 4000W high-power sockets. The socket is too low. When installing sockets, many families feel that it is too high to be beautiful and will be installed in a lower hidden location. It is easy to splash water into the socket when mopping the ground, which leads to leakage accident.

This is how headphone sockets prevent interference. I hope you can understand and learn.
