7216R200L.25 application field and working principle

Rotary Potentiometers and Rheostats

A rotary potentiometer is an electrical device used to control the flow of electricity in a circuit. It has two terminals connected by a resistive element, usually with a third terminal, a wiper arm, that moves along the resistive element\'s surface to modulate the amount of electrical resistance in the circuit. A rheostat is a two-terminal resistor with a wiper arm that moves along its resistive element to modulate the resistance of the circuit.The 7216R200L.25 is a rotary potentiometer and rheostat made by Ohmite. It is designed for use in audio applications and has a low-resistance value of 200 Ohms. It is made of a ceramic body with a gold-plated wiper arm and a carbon element. The 7216R200L.25 is a multi-turn potentiometer and rheostat, meaning that it can be adjusted from a minimum resistance value to a maximum value. Its operation is similar to a rotary encoder, in that the resistance value can be adjusted by turning a knob or shaft. However, the 7216R200L.25 is designed to be more adjustable and precise than a rotary encoder. The 7216R200L.25 is primarily used for audio applications, such as amplifiers and equalizers. It is ideal for controlling the balance between volume and tone in these devices. It can also be used as a voltage divider to provide a precise control of voltage levels in many circuits. The working principle of the 7216R200L is based on the voltage-divider principle. When two resistors are connected in series, the output voltage is determined by dividing the voltage across each resistor. The 7216R200L has two resistors, one fixed and one adjustable, connected in series. The adjustable resistor is connected to the wiper arm, which is used to adjust the resistance of the circuit. By adjusting the amount of resistance in the circuit, the output voltage can be controlled. The 7216R200L.25 is a highly accurate and reliable device. It is designed to have a long life, and can be expected to last for many years with proper care and maintenance. Overall, the 7216R200L.25 is an excellent choice for audio applications, and any other application requiring precise control of voltage levels. Its low resistance and multi-turn adjustment make it an ideal choice for many applications.
