Trimmer Potentiometers are mechanical devices consisting of a resistor with three terminals – a sliding contact (wiper) and two fixed contacts – and are adjustable with a small screwdriver for user-defined resolution. The 3319P-1-224 trimmer potentiometer is designed for applications that require manual adjustment, such as for voltage, frequency, gain adjustment, servomechanisms and security locks. This device offers a high amount of precision and detailed control, while allowing you to maintain repeatability and reliability.

Application Field

The 3319P-1-224 trimmer potentiometer is mainly used in a wide range of consumer and industrial applications. This device is perfect for frequency adjusters, analog-to-digital converters, digital-to-analog converters, sound-level adjusters, electronic motor speed adjusters, pre-amplifiers, power supplies, and any other application that requires fine adjustment from manual control.

This device is also commonly found in the medical industry for medical instruments, monitoring and testing equipment. It is used for manually adjusting blood pressure, respiration rates, heat and humidity levels, oxygen saturation, and other vital parameters. This device is also used in the automotive industry for controlling actuators, such as for cruise control, adaptive headlights, suspension systems, and for airbag deployment.

Working Principle

The working principle of trimmer potentiometers consists of three metal terminals including a wiper, and two fixed contacts with a resistance between them. When the wiper is moved along the resistance as adjusted by the screwdriver, the resistance between the two fixed contacts increases or decreases, thus changing the characteristics of the circuit.

The 3319P-1-224 trimmer potentiometer operates with a low voltage and current, and can be adjusted to within 0.01 Volt. Its contact is a Toradier-Type Bushing that allows it to make contact to the printed circuit board for reliable and accurate adjustment. This device is rated up to 500 volts of operation, and offers a rotational life span of 20,000 cycles.

Overall, the 3319P-1-224 trimmer potentiometer provides a high level of accuracy and repeatability while being simple to use and maintain. This device is a useful and versatile tool that can be used in many industries for a variety of applications.
