A rotary potentiometer is a three-terminal device consisting of a resistive element, wiper, and a rotation mechanism used to measure the angular position of a rotating element within a predetermined range. The resistive element consists of a cylindrical block of dielectric material within which a resistor is embedded in a spiral pattern. A wiper, consisting of two contacts separated by a distance usually less than the width of the resistor, is connected to a rotational shaft. As the shaft is rotated, the two contacts move across the resistor, changing the effective resistance between them and thus providing an output voltage proportional to the angular position of the shaft.

RJS8R0E is a type of rotary potentiometer, designed to provide a precise linear voltage output for position measurement applications. The device is constructed with a conductive plastic potentiometer that is mounted on an output shaft with a diameter of 8 mm. The wiper is a triangular contact type, and it is directly connected to the output shaft for smooth operation and high accuracy. The contact tip of the wiper has been designed to provide optimal stability and low resistance values.

The RJS8R0E is designed to work with a voltage range of up to 48 V, and the output linearity is adjustable in steps of 0.1 Degree/Volt. The device has a maximum resolution of 0.1°, which is suitable for accurate position measurements. The device is also equipped with a low-noise current-sense circuitry for precise output control.

RJS8R0E is especially suitable for applications in control systems, robotics, and factory automation. Its small size and low current requirements enable it to be used in applications with space, power, and cost constraints. It is also highly reliable, with a mean time between failures (MTBF) of 20 million hours.

Besides rotary potentiometers, rheostats are another type of variable resistor. A rheostat is a two-terminal device that consists of an electrical resistor that is adjustable in power, voltage, or resistance by rotating a shaft or sliding a contact along a wire. Rheostats are used in a wide variety of applications, from controlling the volume on a stereo system to regulating the flow of electrical current in an electronic device. They can also be used in electrical motors as a starting mechanism.

Rheostats are also advantageous because they are more reliable than potentiometers due to fewer contact points and easier to manufacture. They have a longer life span and require less power, making them more suited for long-term applications. Like rotary potentiometers, they are used in a variety of applications, such as remote control systems, medical applications, and instrumentation.
