Rotary Potentiometers, Rheostats: 308NPC500K Application Field and Working Principle

Rotary Potentiometers, Rheostats are devices with variable resistors which control flow of current and are widely used in many electronic applications. 308NPC500K is such a potentiometric device which offers users higher performance and reliability over its mechanical and electrical counterparts. This article will explain the application field and working principle of 308NPC500K.308NPC500K is a high precision rotary potentiometer designed for use in the industrial instrumentation field, such as robotics, distributed computer control systems, process control and monitoring applications. It is suitable for a wide variety of tasks that require accurate measurement, such as pressure, current, voltage and temperature. It is designed to handle tough environmental conditions and high vibration.The working principle of 308NPC500K is fairly simple. It consists of three terminals, the two outer terminals are the power supply connections and the center terminal is the adjustable resistance connector. The resistance of 308NPC500K potentiometer is adjusted by changing the position of the rotor. The position of the rotor is given by the contact between the internal contact sleeve and the shaft. When the rotor position is changed, the resistance of the device is correspondingly changed.308NPC500K is designed to be highly reliable and robust in operation. It is constructed of high-grade dielectric material and quality parts. The rotatable contacts are made of alloy steel with precision milled teeth for long life and performance. The contacts are vibration proof, with sealed construction to avoid the entry of dirt, dust or moisture. The device is also provided with a robust housing, which is sealed to maintain long life and protection from harsh environments.Some of the features of 308NPC500K include a tolerance of ±0.005 percent, frequency response up to 10kHz and a maximum voltage rating of 500V. The device is designed to have a long life and is designed to resist corrosion, shock and vibration. It also has an adjustable dead-zone for fine control of resistance and the contact force is set for long life and consistent performance.In conclusion, 308NPC500K is a high precision rotary potentiometer designed for industrial instrumentation applications. It is robust and reliable in operation, and is constructed of high grade dielectric material and quality components. Its features include a tolerance of ±0.005 percent, frequency response up to 10kHz and a maximum voltage rating of 500V. It is also highly resistant to shock, vibration, and corrosion.
