Rotary Potentiometers, Rheostats, RJS12R application field and working principle

Rotary Potentiometers (also known as “pot meters”) and rheostats are resistances that have variable resistance characteristics, and provide a grand low-cost option for measuring, controlling, or limiting electrical current. Primarily, Rotary Potentiometers and rheostats are used as components to adjust or amplify resistance levels of electrical circuits. Rotary Potentiometers and rheostats vary in temperature range, working voltage, and other electrical characteristics such as power rating, mounting type, adjustment type, and resistance range.

The RJS12R is a 12mm rotary potentiometer which is designed for use in a variety of application fields. These include digital systems, analog systems, industrial automation and remote control. RJS12R is made up of a plastic body and a metal shaft with a centrally located wiper contact which moves within a resistive track. The wiper contact is connected to a end terminal, allowing the user to control the resistance level on two different variables – resistance level and rotation of the shaft.

The working principle of the RJS12R is quite simple. As the shaft is rotated, the wiper contact moves along the resistive track, which increases or decreases the resistance seen by the control circuit. The end terminal allows the control circuit to read the resistance at the wiper contact as it moves along the track.

In industrial applications, the variable resistance of the RJS12R can be used to control various parameters such as temperature, humidity, motor speed and air flow. As the resistance changes, so does the input of the controlling system. Using the RJS12R potentiometer, engineers can create robust and reliable remote control systems, automated systems, and test rigs.

In addition to industrial applications, the RJS12R can also be used in consumer electronics products. Audio amplifiers, TV sets, and computer peripherals such as joysticks, keyboards, and track balls all use rotary potentiometers. In fact, most consumer electronics products have dozens of rotary potentiometers and rheostats that are used for volume control, channel selection, and menu navigation.

Overall, rotary potentiometers and rheostats are quite simple yet versatile components that are used in a variety of applications. The RJS12R is a 12mm rotary potentiometer which is designed for use in a variety of application fields, such as digital systems, analog systems, industrial automation, and remote control. The working principle of the RJS12R is quite simple – as the shaft is rotated, the wiper contact moves along the resistive track, which increases or decreases the resistance seen by the control circuit.
