Trimmer Potentiometers

Trimmer Potentiometers, or trimmer pots, are an adjustable resistor used to fine-tune circuitry. Trimmer pots enhance the performance of circuits, allowing precise control over the desired parameters. Often used in digital and analog applications, trimmer pots are versatile and durable. The most common types of trimmer pots are single-turn, multi-turn, force sensitive, and digitally-controlled.

68XR50LF Application Field and Working Principle

The 68XR50LF is a top-of-the-line trimmer pot and it is ideal for applications that require precise control over the desired parameters. It is a multi-turn trimmer pot, meaning it has a full range of adjustment, from 0 to 10 turns. The hexagon screwdriver slot on the 68XR50LF enables accurate adjustment. The rotary shaft of the trimmer pot is constructed with a robust carbon steel with corrosion-resistant gold or black plating. This provides excellent reliability and protection against environmental influences.The internal components of the 68XR50LF consist of a sliding wiper brush, a rotary contact, and an actuator. The wiper brush is attached to the rotary contact, which is mounted on the actuator. When the screwdriver slot is turned, the actuator turns, bringing the rotary contact and wiper brush in contact with each other. This makes contact with the resistive element, allowing the trimmer pot to adjust the resistance value.The 68XR50LF trimmer pot’s resistance range is from 1Ω to 1000Ω; higher and lower values are possible with added components. It is designed for use in low-voltage circuits, and its maximum power rating is 1/4W at +70°C ambient. It is also temperature compensated.The 68XR50LF is an excellent choice for precision applications. This multi-turn trimmer pot provides precise, fine-tuning control over the desired parameters. Its durable construction and temperature compensation make it ideal for demanding applications.
