3549S-1AC-103B

Rotary Potentiometers, Rheostats

A 3549S-1AC-103B is a type of rotary potentiometer, also known as a rheostat. Rotary potentiometers work as a voltage divider, setting the voltage output relative to the angle of the wiper when it is rotated. The 3549S-1AC-103B is a particularly special type of potentiometer, since it boasts an exceptionally rugged construction and automated adjustable resistance. This device\'s application field and working principles are discussed in further detail below.

Applications

The 3549S-1AC-103B is an industrial-grade, heavy-duty appliance, and as such is suitable for a vast range of applications. Firstly, the device is able to stand up to extreme temperatures and provide reliable performance in temperatures ranging from -55°C to +140°C. Further, the device is resistant to shock and vibration, and has a robust construction perfectly suited for hostile environments.In terms of industrial applications, the 3549S-1AC-103B can be used in a number of controlled processes where resistance needs to be adjusted regularly. It can therefore be used in motor control systems, in taps and valves for hydraulic systems, and in measuring instrumentation. Further, its adjustable resistance feature can be utilised in a range of devices, from fuel and oil level sensors, circuit breakers to level detectors and relays.

Working Principles

The 3549S-1AC-103B is a three-terminal component, usually available in a form that is slim and integrated for easy installation within existing circuits. The device is powered by a voltage source, typically a DC or AC power supply, and then it can output a certain amount of resistance based on how much of the resistance track is engaged at any one time. This is controlled by an adjustable wiper, which can be moved in a clockwise or counterclockwise direction, thereby increasing or decreasing the resistance level respectively. When the wiper is moved along the track, it makes contact with the resistance track and this decreases as it moves further away from the two outer terminals.When the resistance is increased or decreased depending on the desired output level, voltage dividers come into play in order to calculate the resistance and the end voltage. The voltage dividers are used to calculate the voltage output associated with the adjustable resistance, which is useful in applications where a user needs to be able to manually adjust the output voltage.

In conclusion, the 3549S-1AC-103B is a three-terminal rotary potentiometer, designed for an array of industrial applications. It is able to withstand a wide range of temperatures, is resistant to shock and vibration, and its adjustable resistance can be used to great effect in motor control systems, measuring instrumentation, and fuel and oil level sensors, among others. As a result, it is an extremely useful device for a range of industrial and home applications, and is becoming even more popular as technologies advance.
