SM-42B205

Trimmer potentiometers are adjustable resistors used to set specific resistance levels based on an input voltage. The SM-42B205 trimmer potentiometer is a single turn, board mounted potentiometer with a wide variety of application fields and working principles.The SM-42B205 is a potentiometer with a very high resolution. It is ideal for applications where an exact resistance, or an adjustable output voltage, needs to be maintained. The stable voltage range of the SM-42B205 typically lies between 5V and 15V, and the resistance value can be adjusted by a simple turn of the shaft.The SM-42B205 is typically used in a variety of applications, including automotive, industrial, consumer, medical, space-borne, and military applications. It is very popular in applications involving the control of current, voltage, or frequency. It can also be used as a variable resistor in devices such as audio signal processors, amplifiers, and oscillators.The working principle of the SM-42B205 is based on the Hall effect. The SM-42B205 has two resistance elements: a fixed resistor, and a variable resistor. The variable resistor is a rotational device which is connected to a metal wiper arm. As the potentiometer rotates, the wiper arm moves along the resistor, changing the resistance of the variable resistor. The Hall effect sensing element is used to measure the resistance of the fixed resistor and the variable resistor.The output voltage of the potentiometer is proportional to the resistance of the two resistors. When the wiper over the variable resistor is adjusted, the resistance of the fixed resistor and the resistance of the variable resistor can be changed, resulting in a change in the output voltage. Additionally, the SM-42B205 can be adjusted to change the sensitivity of the output voltage, allowing for more versatility.The SM-42B205 is a highly versatile trimmer potentiometer due to its wide range of application fields and the comprehensive range of output voltages. It offers high precision and reliability, with a long operating life. Furthermore, it is able to maintain very close resistance values, making it ideal for applications where an exact resistance is needed.
