Rotary Potentiometers, Rheostats are commonly used electrical components with a wide range of application possibilities. This article will focus on the application field and working principle of 3549H - 1AC - 502A, a specific type of such components.

Purpose and Overview

The 3549H - 1AC - 502A is used as a resistive settings device in electronic circuits to control/adjust current, voltage or resistance. As a rheostat, it can be used as a controlling component for tuners, sonar equipment and DC drives. As a potentiometer, it can be used to adjust the brightness of lights, voltage output levels and in temperature sensing units.

Construction Details

The 3549H - 1AC - 502A is a single turn rotary component, with a resistance of47KΩ maximum. It consists of a carbon disc or track mounted on a shaft, and a support frame that holds the disc in its desired position. The frame is equipped with a metallic contact, which, in turn, is connected to the terminals of the component. The 3549H - 1AC - 502A is usually composed of a conductive element, a wiper and a resistive element.

Working Principle

The working principle of the 3549H - 1AC - 502A is quite simple. When the component is connected to a power supply, current passes through the resistive element. As the disc or track is rotated, the wiper contacts one point of the resistive element at a time, thus varying the resistance. This change in resistance causes a variation in the amount of electric current that is flowing through the circuit, which is what is actually being controlled by the component.

Advantages

The 3549H - 1AC - 502A has several advantages compared to other resistive settings devices. The main advantage is its compact design, which allows it to be mounted in tight spaces. This component is also quite inexpensive and has a long lifespan with minimal maintenance. Finally, it is highly resistant to heat, shock and vibration, allowing it to be used in harsh environments.
