Trimmer Potentiometers

Trimmer Potentiometers is a type of adjustable resistor comprising three terminals. Two terminals are used to supply the voltage, and the third terminal is used to adjust the electrical resistance of the device. These devices are used in a variety of electrical and electronic controls, ranging from simple resistors to complex feedback systems.

The FT63ETH200 is a trim pot from the FT63 series of Trimmer Potentiometers, and is designed for applications in digital and analog circuits. The device features a linear taper and a resistance range of 200 ohms. The device is constructed of epoxy and has non-magnetic elements which ensure that the characteristic resistance value is maintained.

The FT63ETH200 can be used in many applications, such as volume control for amplifiers, audio signal attenuators, and to adjust resistance in a power amplifier circuit. It can also be used in touch-tone dialing circuits, automatically adjusting loads to desired values, and as an adjustable resistor element in test and measurement equipment. The FT63ETH200 also finds applications in sensing applications such as wheels to optimize weighing scales.

The working principle of the FT63ETH200 is based on varying the resistance through a change in its physical shape. It consists of two contact arms, one connected to each of the terminals. The resistive element is made of conductive plastic, while the contact arms are spring-loaded, allowing them to move against the resistive element. It is the relative movement between the two contact arms and the resistive element which controls the resistance of the Trimmer Potentiometer.

The adjustment of the FT63ETH200 is made by rotating the adjustment knob on top. As the knob is rotated, the contact arms move along a helical path, which allows an almost infinitely variable resistance adjustment. The adjustment of the FT63ETH200 is performed in four fixed steps, which can be used for accuracy or automation, and precise resistor adjustment is attained through a suitable control system.

The FT63ETH200 is a versatile Trimmer Potentiometer with low power consumption and a low absolute minimum resistance of 200 ohms. Its flexibility of resistance adjustment and high reliability make it one of the most commonly used adjustable resistors in electronic and electrical applications.
