Trimmer Potentiometers

Introduction

A trimmer potentiometer, also known as a trim pot or trimpot, is a small electronic adjustable three-terminal device used to vary an electrical resistance in a circuit. Trimmer potentiometers are often packaged with a screwdriver-style actuator, allowing an easy fine adjustment to be made in the circuit. They are popular in consumer electronics and automotive electronics for precisely adjusting the settings of equipment.

Types of Trimmer Potentiometers

Trimmer potentiometers come in several varieties: rotary, slide, and digital.

Rotary Trimmer Potentiometers

Rotary trimmer potentiometers are the most common type and are available in single and multi-turn configurations. In a single-turn potentiometer, the shaft is only able to turn about one full turn, and in a multi-turn potentiometer, the shaft can turn multiple revolutions. They are designed for setting small, precise changes in a circuit, typically for fine tuning or calibration. A common example is adjusting the RF gain in a wireless device.

Slide Trimmer Potentiometers

Slide trimmer potentiometers are similar in design to rotary trimmer potentiometers, but they use a slidable contact instead of a rotating shaft. This type of trimmer is ideal for use in portable electronics, as they are available in small surface-mount packages.

Digital Trimmer Potentiometers

Unlike their mechanical counterparts, digital trimmer potentiometers use electronic components to control the resistance instead of a mechanical shaft. This type of trimmer is typically used in applications where accuracy and repeatability are important, such as for fine tuning mechanical or electrical systems.

23SR50LFTR Application Field and Working Principle

The 23SR50LFTR is a trimmer potentiometer manufactured by Bourns Inc. It is a single-turn, slide-type potentiometer with an adjustable resistance range of 10R to 50R. The 23SR50LFTR is designed for use in high-precision instrumentation and automotive applications requiring precise setting of a resistance value.The operation of the 23SR50LFTR is based on a sliding contact that moves along a first terminal and a second terminal which is the contact point to create a resistance. When the slider is moving along the track, the resistance value changes accordingly. The contact material of this trimmer is made of nickel-plated brass with a wiping pressure of 0.1N. The contact point is made of silver and a wear limit of 0.3mm is guaranteed before the contact must be re-adjusted. The temperature coefficient of resistance (TCR) is +200ppm/C and its operating temperature range is -25C to +85C. The 23SR50LFTR is available in two sizes: a 16.5mm long body with an 8mm travel and a 37.5mm body with a 15mm travel, and in both metric and inch sizes. In addition, the 23SR50LFTR is available with a wide variety of mounting options including plastic belt and surface mount packages.

Conclusion

Trimmer potentiometers are an important component used in a variety of applications, from fine tuning equipment settings to precision instrumentation. The 23SR50LFTR is a single-turn, slide-type trimmer potentiometer manufactured by Bourns Inc. that can be used in high-precision applications requiring precise adjustments. It is available in two sizes, and with a variety of mounting options.
