At present, the market of optical potentiometer products at home and abroad is blank, and the market is very broad. Optical potentiometer is the most suitable product for industrial production control equipment and has the most use value. If the optical potentiometer is adopted, similar faults will not occur within ten years, which is indeed guaranteed for production

The incremental rotary encoder converts the timing and phase relationship of its angle code disk through two internal photosensitive receivers to obtain the increase (positive direction) or decrease (negative direction) of the angle displacement of its angle code disk. After connecting the digital circuit, especially the single chip microcomputer, the incremental rotary encoder is more absolute in angle measurement and angular velocity measurement

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
