From the outside, the pulse potentiometer has three pins like the ordinary potentiometer, but internally, two metal static plates of different lengths are connected with pins 1 and 2, and a metal moving plate with 12 or 24 teeth around pin 3. When the pulse potentiometer rotates, there are four states: pin 3 and pin 3

In fact, the working principle of the four pin light touch switch is similar to that of the ordinary button switch. It is composed of normally open contacts and normally closed contacts. In the four pin light touch switch, the function of the normally open contact is that when pressure is applied to the normally open contact, the circuit will be in the on state; When this pressure is removed, it returns to

The number of bits of the single turn absolute value encoder represents the number of code channels of the code disk. Because the binary code disk is used (the gray code is the same), its accuracy becomes several powers of 2, for example, 12 bits is the 12th power of 2, that is 4096. The resolution and accuracy of the encoder are not necessarily the same, and the accuracy varies with the score, mechanical concentricity of the code disk and reading

There is no fixed answer. Many factors play a role, the maximum cable length connecting devices together. The biggest problem with using long cables is that the cables become more vulnerable to noise interference. This is due to the capacitance of the cable. The cable works like an antenna, and there will be loss of power through the cable. The maximum distance of the cable can be obtained

Potentiometer becomes smaller, simpler and more accurate. Its development tends to be miniaturized, high efficiency, high quality and low loss. With the wide application range of modern electronic equipment, the service conditions are becoming more and more mature. Then, how to correctly select potentiometers under different conditions? The specific contents are as follows: condition 1, high-power electricity
