TC86W-1-502 Potentiometers, Variable Resistors

Trimmer Potentiometers, such as the TC86W-1-502, have become increasingly important and widely used in various precision measurement and control applications. This article outlines the application field and working principle of the TC86W-1-502 device.

Application Field

The TC86W-1-502 trimmer potentiometer has a range of practical applications due to its ability to accurately adjust resistance values. It is commonly used in audio equipment and other electronic circuits, such as radios, stereos, amplifiers, and equalizers. It is also commonly used in industrial applications, such as machine tools, robotics, and servos. It can be used to adjust the brightness of LED lighting, as well as the speed of motors. In addition, it is often used in automotive applications such as fuel pumps, windscreen wipers, and airbag systems. Overall, the TC86W-1-502 trimmer potentiometer is suitable for a wide variety of precision measurement and control applications.

Working Principle

The TC86W-1-502 trimmer potentiometer works by adjusting the resistance between two terminals according to the knob’s setting. The device consists of a resistor connected to two terminals at one end, and a rotating knob at the other end. As the knob is turned, the resistors parameters are adjusted. This is done by varying the angle of the contact between the terminals and the resistor element, or by changing the length of the resistor element. In other words, turning the knob changes the resistors values and this produces a corresponding change in the resistance between the two terminals.

The TC86W-1-502 is also equipped with a built-in thermistor, which is used for temperature compensation. This thermistor detects any changes in ambient temperature, and compensates for these variations by automatically adjusting the resistance between the two terminals. This thermistor-based temperature compensation ensures that the device’s performance remains consistent in all environmental conditions.

Conclusion

The TC86W-1-502 trimmer potentiometer is a versatile and accurate device with a wide range of practical applications. It is suitable for use in audio equipment, industrial machinery, and automotive systems, and its built-in thermistor provides temperature compensation for consistent performance. The device works by adjusting the resistance between two terminals according to the knob’s setting, and the output can be precisely calibrated for accurate control and measurement.
