Rotary Potentiometers, Rheostats
EVJ-Y81F30B24 is a rotary potentiometer-rheostat which is commonly used in applications such as audio, motor and circuit protection. It can also be used as a voltage or current divider or as an adjustable resistance element in a circuit. The device is mechanically operated by turning a spindle and knob, and provides a variable resistance.
Application Field
EVJ-Y81F30B24 is extensively used for volume and balance control in audio equipment like stereo amplifiers, tape recorders, mixing consoles, equalizers, etc. It is also used in a wider range of industrial applications such as speed, position, and intensity control. Its adjustable resistance can be effectively used for creating safety barriers in relays and motor control circuits. It can also be used as digital encoders to convert the movement of an object into a digital signal.
Working Principle
EVJ-Y81F30B24 consists of a resistance element which is connected in a circuit, along with a spindle rotating on a shaft. This resistance element, when the shaft is turned, changes its characteristics and provides varying resistance in the circuit. The type of resistance is either a potentiometer, a rheostat, or an adjustable resistor. A potentiometer is a three-terminal device with two fixed resistors and a sliding contact that determines the resistance across the circuit. A rheostat is a two-terminal device with a fixed resistor and a sliding contact, where the sliding contact determines the resistance across the circuit. An adjustable resistor is a two-terminal device with a variable resistor, where the position of the resistor determines the resistance across the circuit.
When the spindle is rotated, the resistance between the two fixed resistors in a potentiometer changes and consequently the resistance across the circuit. This resistance across the circuit can be varied simply by rotating the spindle or knob. In a rheostat and adjustable resistor, the resistance across the circuit is achieved by varying the position of the sliding contact with respect to the fixed resistor.
EVJ-Y81F30B24 provides an accurate and reliable resistance value, making it suitable for such industrial applications. It has a low cost and low power consumption, making it an ideal choice for industrial applications.
