DC socket manufacturer hot selling electronic components DC socket, although many people are in use, in the acquisition, but it is not clear what the safe scale of DC socket carrying current is.
DC socket series of new photoelectric switches generally have the function of actively avoiding disturbance to each other, so there is no need to worry about disturbance to each other. However, when several groups of infrared photoelectric switches are parallel to each other, adjacent groups and mutual disturbance should be avoided. The most useful way to avoid such disturbance is to insert the projector and receiver. Set the distance between groups when crossing the group. Secondly, it is also a good way to use different frequencies of machines. The useful way to avoid disturbing each other is to swing the distance. The farther the DC socket and the detection distance are, the farther the distance should be. Detailed distance should be determined according to the debugging situation. Of course, it can also be used without disturbing each other. Types of machines with the same operating frequency.
Scanning the effect of scene: When using reflective scattered projection, the receiver may sometimes make the photoelectric switch unstable because the detected object is close to the scene, the photoelectric switch or the scene is a high reflectivity object such as lubrication. The mirror angle influences: When the measured object is glossy or encounters a lubricated metal surface, 1. Generally, the reflectivity is very high and has the effect of approximating the mirror. At this time, the angle between the projector and the detecting device should be made so that the optical axis of the projector is not perpendicular to the detected object. DC socket can then avoid misoperation.
DC socket manufacturer analysis that the demand for electricity in winter is larger, some users like to plug computers, electric heaters and so on into the same multi-purpose socket, although it is very convenient to use, but there are great security risks. In terms of electric heating, its starting current is very large, if it starts at the same time with other high-power appliances, socket connection. Points and leads will be difficult to withstand the unexpected excessive load of electricity, interaction and even damage the electrical appliances themselves, and even accidents.
When DC socket is installed, the open socket should be no less than 1.8 meters from the ground and the concealed socket should be no less than 0.3 meters from the ground. In order to avoid children's electric shock, it is necessary to select a safe socket with a stable shield to pinch the hole of the power supply with finger contact or metal objects.
Do you want to know how the headphone socket achieves current transmission, how the transistor works, and how they achieve the desired effect when we use it?
When the headphone socket transistor is full, the collector potential is very low or even close to or slightly lower than the base potential. The collector junction is at zero bias, but there will still be a large reverse current Ic of the collector junction. When the current expands, the primary current in the transistor is from the emitter region to the base region. The collector is composed of transistors, i.e. the current through the transistors. The first headphone socket of the IC is an electronic current, which is very similar to the electronic transistors in history.
The current amplification principle of electronic triode can be explained naturally because of its intuitive image. It is easy to understand that the fixed share relationship between Ib and Ic of electronic triode depends primarily on the structure of gate (base) of electronic transistor. When the external circuit conditions are satisfactory, the operation of electronic triode is expanding. In the case of enlargement, the main current passing through the tube is the electron current from the emitter through the gate to the collector.
When the electronic current of the headphone socket passes through the gate, it is obvious that the gate will intercept the current. There is a question about the interception ratio when intercepting the current. The size of the interception ratio is mainly related to the density of the gate. If the gate is dense, its equivalent interception area will be large, and the interception share will naturally be large, and the blocked electronic current will be large. More, conversely, the interception ratio is small, and the blocked electron flow is less. The blocked electron flow by the gate is current Ib, and the other electron flow passing through the gate to the collector is Ic.
As long as the structure scale of the gate is determined, then the cut-off share is determined, that is, the ratio of Ic to Ib. Therefore, as long as the internal structure of the tube is determined, the value is determined, and the ratio is fixed and unchanged. It can be seen that the beta value of the current expansion factor is primarily related to the sparse density of the gate.
