Thumbwheel Potentiometers are electromechanical devices used to measure current, voltage, or resistance. They are used in a variety of applications, such as laboratory use, production line testing, and controlling current flow. The 1625938-5 is a type of thumbwheel potentiometer specifically designed for high current applications.

The 1625938-5 thumbwheel potentiometer boasts an impressive array of features, including its current ranging ability from 5A to 30A and its resistance range of 0.5 ohms to 3 kilo-ohms. It is designed to be durable and has a built-in self-locking mechanism, meaning it can be used in confined spaces where other potentiometers cannot. The 1625938-5 also has a unique “B” contactor design that allows it to act as a floating contactor, providing maximum versatility.

Application Field

The 1625938-5 thumbwheel potentiometer is commonly used in both industrial and domestic electrical applications. This is because of its impressive current ranging ability from 5A to 30A and its resistance range of 0.5 ohms to 3 kilo-ohms. Its “B” contactor design, which allows it to act as a floating contactor, allows it to be used in environments where other potentiometers cannot.

In industry, this thumbwheel potentiometer is used in a range of applications including welding, soldering, laboratory use, production line testing, and controlling current flow. It is also frequently used in projects in automotive, industrial, and healthcare industries.

Working Principle

The working principle of the 1625938-5 thumbwheel potentiometer is based on a potentiometer element which is connected to an external circuit. This external circuit is composed of two potentiometer elements, a variable resistor or rheostat and a resistance wire or a slide wire. Depending on the setting of the rheostat, the resistance of the potentiometer element is altered. The resistance of the potentiometer element changes as the thumb wheel of the potentiometer is turned. This alteration in resistance affects the current flow through the external circuit.

The 1625938-5 thumbwheel potentiometer has a built in self-locking mechanism which prevents the accidental change of its setting. This feature makes it an ideal choice for use in environments where the setting of the potentiometer may need to be adjusted regularly.

In summary, the 1625938-5 thumbwheel potentiometer is a versatile device which can be used in a range of industrial and domestic electrical applications. It is designed with a wide range of features, including current ranging abilities, and a self-locking mechanism. Its working principle is based on a potentiometer connected to an external circuit which is affected by the resistance of the potentiometer element when the thumbwheel is turned.
