Chassis Mount Resistors: RSH-125-50 Application Field and Working Principle

Resistors are electrical components designed to limit the flow of electricity in an electronic circuit. Chassis mount resistors are resistors that are mounted to a metal case, as opposed to “through-hole” or “surface-mount” resistors. One example of a chassis mount resistor is the RSH-125-50.The RSH-125-50 is a potentiometer designed to be mounted onto metal with a standard M10 screw. It is a single-turn, linear resistor designed to control the voltage in a circuit by allowing more or less voltage to pass through the resistor. It consists of a resistor element and a contact or wiper that is easily adjustable with a small screw or knob. It can withstand up to 125 watts of power and its contacts are plated with silver for improved durability and performance.The RSH-125-50 is commonly used in audio equipment and electric motor control applications. When used in audio applications, the potentiometer can be used to control the volume or tone of the device. It can also be used to adjust the frequency response by providing fine-grained control of the signal coming into the device. In electric motor control applications, the RSH-125-50 can be used to adjust the voltage or current going to the motor, allowing for more precise control over the speed and torque of the motor.The working principle of the RSH-125-50 is relatively simple. When the small screw or knob is adjusted, the contact or wiper moves along the resistor element. This allows for more or less voltage to pass through the resistor, depending on the position of the contact. Signals with higher amounts of voltage are sent to the resistor, where they are then restricted and directed to their intended destination.In conclusion, the RSH-125-50 is a versatile chassis mount resistor that is commonly used in audio equipment and electric motor control applications. Its simple design and robust construction allow it to withstand high amounts of power, while its adjustable contact provides reliable control over the voltage passing through the resistor. With its high quality components and adjustable contact, the RSH-125-50 is a great choice for projects requiring a reliable and efficient resistor solution.
