Slide potentiometers are one of the most versatile and widely used linear position sensors. The PSM01-081A-105A4 is a dual-gang slide potentiometer, characterized by its dynamic and precise feedback thanks to its 10 trajectory contacts, which have been designed for excellent electrical and mechanical stability. Its applications span a broad range of domains, from motion control to medical equipment and consumer electronics.

A slide potentiometer usually consists of three terminal connections – ground, sum, and wiper – and operates in two modes, resistance (not current) mode and voltage mode. When in resistance mode, the wiper terminal is connected to the sum terminal, causing the effective resistance of the potentiometer to change according to the position of the wiper. In contrast, when the potentiometer is in voltage mode, the wiper terminal is disconnected from the sum terminal and a voltage is applied across the sum and ground terminals. As the wiper is then moved, the voltage at the sum terminal will increase or decrease in proportion.

The PSM01-081A-105A4 has an overall resistance range of 5k ohms to 25k ohms and is typically used in servo motor drive systems. In such a system, the potentiometer is connected to a servo motor such that when the motor is running in forward mode, the wiper is driven towards the right terminal; and when the motor is running in reverse mode, the wiper is moved towards the left terminal. The voltage seen at the sum terminal is then proportional to the speed of the motor, providing a feedback signal that can be used to accurately control the motor’s speed.

The PSM01-081A-105A4 also employs a Wheatstone bridge configuration. This configuration utilizes four balanced resistors, arranged symmetrically, such that a change in the wiper resistance will alter the output voltage at the sum terminal. Depending on the direction in which the wiper is being moved (towards or away from the sum terminal), the sum terminal will experience an increase or decrease in voltage, thus providing more precise and accurate results than a single resistor configuration.

The PSM01-081A-105A4 is also immune to gravitational effects and shock as the wiper is stabilized with the help of a stainless steel spring. Furthermore, the potentiometer is designed with 10 contacts for superior electrical and mechanical stability, and its high accuracy ensures that only minimal adjustment is required when new applications are developed.

In short, the PSM01-081A-105A4 is a reliable, versatile, and accurate dual-gang slide potentiometer that is suitable for a variety of applications, including servo motor drive systems, medical equipment, motion control, and consumer electronics. Its 10 trajectory contacts provide excellent electrical and mechanical stability while the Wheatstone bridge configuration allows for precise and accurate output signals.
