Potentiometer is a resistance element with three leads and the resistance value can be adjusted according to a certain change law. Potentiometers usually consist of a resistor and a movable brush. When the brush moves along the resistance body, the resistance value or voltage related to the displacement is obtained at the output end. The main functions of potentiometer in the circuit are as follows

1. The resistor of the potentiometer is mostly made of polycarbonate synthetic resin. Avoid contact with the following items: ammonia, other amines, alkaline aqueous solution, aromatic hydrocarbons, ketones, aliphatic hydrocarbons, strong chemicals (high pH value), etc., otherwise its performance will be affected. 2. The terminal of the potentiometer is welded

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

What is an incremental rotary encoder? The incremental encoder provides a certain number of pulses for each rotation of the shaft. Periodic measurements or pulse counts per unit time can be used to measure the speed of movement. If the number of pulses is accumulated after a reference point, the calculated value represents the parameter of rotation angle or stroke

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
