Rotary Potentiometers, Rheostats are widely used in a variety of control and regulation electronics. The P13SMNFLS473MA is an example of one such device, which has many applications and a unique working principle.

Application Field

The wide range of applications for the P13SMNFLS473MA includes voltage and light regulation, sound and frequency adjustment, climate control, HVAC settings, and flow rate control in fluids and gases. Additionally, these potentiometers are suitable for various applications in industrial, automotive, instrumentation, consumer, professional audio/ video, and audio/appliance markets.

Thanks to their multipurpose structure, these devices are most commonly used to adjust voltage or current levels in DC circuits, to reduce sound or light intensity, and to control flow rate in pipes for liquid and gas applications.

The P13SMNFLS473MA features a long-life, reliable design, which contribute to their use in safety and convenience applications. These potentiometers also feature an adjustable shaft length and conveniently operate at low voltage levels.

Working Principle

The P13SMNFLS473MA uses a three-terminal potentiometer. This type of potentiometer consists of a strip of resistive material connecting three terminals. Applying a voltage to two of the terminals creates a voltage across the resistive strip, with the voltage at the third terminal depending on the position of a moveable contact along that strip. This contact is known as the wiper, and by adjusting its position along the resistive strip, the voltage at the third terminal can be varied. Periodic rotations of the external control shaft moves the wiper along the strip, thus increasing or decreasing the value of the output voltage.

Depending on various components, the resistive strip can have linear, logarithmic, or reverse-logarithmic characteristics..

In the case of the P13SMNFLS473MA, the resistance range is 0–10 kΩ, the power rating is 1 W, and the temperature range is −25°C to +85°C.

The P13SMNFLS473MA also features superior linearity with ±1% or less deviation, ensuring precise voltage and light regulation, sound and frequency adjustment, climate control, HVAC settings, and flow rate control in fluids and gases. This makes the device suitable for a broad range of high-precision applications.

The combination of adjustable shaft length, long life, reliable design, and a wide range of usage options make the P13SMNFLS473MA a valuable part of any circuit board, especially when lightweight designs and low operating voltage levels are required.
