Classification of piher spain potentiometer

The key components of piher spain potentiometer are resistors and brushes. Potentiometers can be divided into several types according to their structure and whether they have switches or not.

Piher spain potentiometer can also be classified according to the materials of resistors, such as wire winding, synthetic carbon film, metallic glass glaze, organic solid core and conductive plastics. The electrical properties are mainly determined by the materials used. In addition, potentiometers made of metal foil, metal film and metal oxide film are also used for special purposes. Potentiometers can be divided into general, high precision, high resolution, high resistance, high temperature, high frequency and high power equipotentials according to the characteristics of their use, and adjustable, semi-adjustable and fine-tunable potentiometers according to the way of resistance adjustment, the latter two are also called semi-fixed potentiometers. In order to overcome the adverse effects of brush moving contact on resistor on potentiometer performance and life, contactless non-contact potentiometers, such as photosensitive potentiometers and magneto-sensitive potentiometers, are available for a small number of special applications.

 Wire-wound potentiometer: It has the advantages of high precision, good stability, small temperature coefficient, reliable contact, high temperature resistance and strong power load capacity. The disadvantages are that the resistance range is not wide enough, the high frequency performance is poor, the resolution is not high, and the wire-wound potentiometer with high resistance is easy to break, the volume is large and the price is high. This potentiometer is widely used in electronic instruments and instruments. The resistance body of wire-wound potentiometer is made up of resistance wires wound on insulators. There are many kinds of resistance wires. The material of resistance wires is selected according to the structure of potentiometer, the space of holding resistance wires, resistance value and temperature coefficient. The thinner the resistance wire, the larger the resistance value and resolution in a given space. But the resistance wire is too thin and easy to disconnect during use, which affects the life of the sensor.            

Adjustable winding potentiometer SYNTHETIC CARBON FILM SPAIN POTENTIOMETER: It has the characteristics of wide resistance range, good resolution, simple process and low price, but it has high dynamic noise and poor moisture resistance. This kind of potentiometer should be used as functional potentiometer, which is widely used in consumer electronic products. The printing process can automate the production of carbon diaphragm.            Carbon film potentiometer            

Organic solid-core piher spain potentiometer: wide range of resistance, high resolution, good heat resistance, strong overload capacity, good wear resistance, high reliability, but poor moisture resistance and thermal and dynamic noise. This kind of potentiometer is usually made into a small semi-fixed form, which can be micro-invoked in the circuit.            

Metal glass glaze potentiometer has the advantages of organic solid core potentiometer and smaller resistance temperature coefficient (similar to wire wound potentiometer), but it has large dynamic contact resistance and high equivalent noise resistance, so it is mostly used for semi-fixed resistance adjustment. This kind of potentiometer has developed rapidly, and its ability to withstand temperature, humidity and load shock has been improved. It can work reliably under harsh environmental conditions.
