Trimmer Potentiometers play an important role in adjusting the variables in electrical equipment, ranging from audio to precision navigation. The 3269P-ES2-105 is a trimmer potentiometer that is used to trigger relays or other switches for the control of signal level. It comes with an easy-to-set range and an adjustable screw to calibrate the maximum and minimum limit.

The 3269P-ES2-105 is intended as a three-terminal, open-circuit adjustable resistance device that works by incorporating a calibrated resistor for resistive divider applications. It is well-suited to a wide range of applications in industries where accurate measurement is a must, such as aviation, navigation, telecommunication, medical, metrology, and electronics.

The primary application field for the 3269P-ES2-105 is in portable audio, where its use ensures balance is maintained between elements of the signal chain. The device can be used to achieve radio and TV frequency tuning as well as in closed-loop feedback control to regulate the output of system components such as LEDs and LCDs.

The 3269P-ES2-105 potentiometer works due to the presence of three resistors on the circuit board, as well as additional wiring that carries signals across to the wires. The internal circuit on the trimmer potentiometer connects two of the resistors, with the trimming resistor in the middle. The resistor values can be adjusted by moving the trimming resistor’s contact to different positions.

The active portion of the trimmer potentiometer, the third terminal, is used to adjust the resistance, creating a voltage level across the trimming resistor. The active terminal works in conjunction with the maximum and minimum limit screw to confine resistance to a specific range. It is important to note that the active terminal of the device should not be used for any other purpose.

The 3269P-ES2-105 trimmer potentiometer provides electrical equipment with enhanced audio-visual capabilities and flexibility. With its resistance range adjustable by a single screw, the device allows precise triggers and adjustments to be made. This trimmer potentiometer is designed with safety in mind, incorporating multiple insulation layers to prevent electric shocks.
