Trimmer Potentiometers: CT-94Y-201 application field and working principle

Trimmer potentiometers, also known as trimmers, trimmer resistors, trimmer capacitors and trimmer inductors, refer to electronic components that are adjustable in the range of a few ohms to a few megohms and nanofarads to a few microfarads. Potentiometers are one of the most basic electrical components, which can be used as voltage dividers, but also as analytical tools for signal testing. They can be divided into several types according to their size, shape, frequency range and number of revolutions. This article will focus on the application field and working principle of CT-94Y-201, which represents one of the more popular types of trimmer potentiometers.

Application field

CT-94Y-201 trimmer potentiometers can be used in a wide variety of applications and is increasingly popular in today’s industries. This trimmer is commonly used to adjust the parameters of electric & electronic products, and is mainly used in two ways.

1. The user can adjust the precision of the electronic product through the turning of CT-94Y-201 during the initial testing and tuning process, including the current, temperature, pressure, resistance, voltage, etc.
2. The user can adjust the scale of the electronic product online in real time after the product is tested and adjusted by the CT-94Y-201 trimmer pot, and can also wind off the switch scale to adjust the rheostat.

Application of CT-94Y-201 in different fields is similar, and usually it is used as a small analog signal adjust switch, such as temperature and pressure control in bio-medical and chemical instruments, temperature, height and lighting control in automation system, and sound volume, TV channel and brightness control in multimedia devices.

Working principle

The basic working principle of a trimmer potentiometer is as simple as the mechanism of a variable resistor. It consists of resistive carbon track, a wiper which functions as a fixed contact, a shaft or arm which acts as a movable contact, and a terminal or bushing for connecting the resistance element within the potentiometer. The resistance can be adjusted by moving the wiper in the parameter direction from left to right across the graph.The CT-94Y-201 is an adjustable trimmer potentiometer, which mainly consists of three parts: the adjusting screw, the controlling shaft and the pot core. When the adjusting screw moves along the center of the circuit, the resistance of the potentiometer can either increase or decreases co-linearly.The CT-94Y-201 trimmer pot adopts the structure where the traces are formed on the isolation board surface. The two ends of the traces form two bottom layers, together with the adjusting pad as the third layer, insulating the top layer and the adjusting pad from each other. This isolate structure ensures that no short circuit might occur on the surface of the trimmer.This trimmer parameter has advantages such as high stability, high error rate and strong long-term environment adaptability. To conclude, the CT-94Y-201 trimmer pot is perfect for a wide range of applications due to its adjustable resistance range and high stability.
