Rotary Potentiometers, Rheostats and the 62JA20K application field and working principle

Introduction

The 62JA20K is an advanced rotary potentiometer, rheostat, and unique voltage dividers. It comes in a standard 0.25", 0.5", 1.25", 2.00", 3.00" and 6.00" package. It is designed to be used in applications such as controlling the speed of motors, controlling the temperature in ovens and refrigerators, measuring the pressure of liquids and gases, and measuring the voltage of automotive components. It has a wide operating temperature range of -10℃ to +125℃ and is rated for currents up to 10mA with a voltage span of 24VDC. The 62JA20K is available in three sizes which include the R1, R2 and R3.

Rotary Potentiometer

The 62JA20K is used as a rotary potentionmeter and works by sending variable resistance signals to the device being controlled. It consists of a shaft, a wiper, a resistance element, and a microswitch. The resistance element is a carbon-film, wire-wound, or multi-turn element which is connected to two external terminals: one at each end. The wiper is attached to the shaft and slides along the resistance element, sending a varying resistance signal to the device being controlled. This varying resistance signal is used to alter the operating characteristics of the device being controlled.

Rheostat

In addition to being used as a potentiometer, the 62JA20K can also be used as a rheostat. A rheostat works by limiting the amount of current that is allowed to flow in a circuit. This is accomplished by sending a variable resistance signal to the device being controlled, which then adjusts the current flow accordingly. The 62JA20K can be configured to limit the current flow up to 10mA. This makes it suitable for use in controlling the speed of motors, or for use in controlling the temperature in ovens and refrigerators.

Voltage Dividers

The 62JA20K can also be used as a voltage divider. A voltage divider is a device that divides a voltage input into two or more outputs. The 62JA20K can be configured to divide a voltage input of up to 24VDC. This makes it suitable for measuring the pressure of liquids and gases, or for measuring the voltage of automotive components.

Conclusion

The 62JA20K is an advanced rotary potentiometer, rheostat, and unique voltage dividers. It is designed to be used in applications such as controlling the speed of motors, controlling the temperature in ovens and refrigerators, measuring the pressure of liquids and gases, and measuring the voltage of automotive components. It has a wide operating temperature range of -10℃ to +125℃ and is rated for currents up to 10mA with a voltage span of 24VDC. The 62JA20K is available in three sizes which include the R1, R2 and R3.
