Rotary Potentiometers, Rheostats

The 3851A-162-104BL is a rotary potentiometer, rheostat. It is used for a variety of electrical applications, such as controlling the speed of motors, adjusting audio output, stimulating transistors and controlling the flow of electricity.

A rotary potentiometer is a three-terminal resistor, with a variable resistance between terminals 1 and 2. This resistance is adjusted by rotation of the control knob, which moves a wiper along the resistive element. Terminal 3 is a preset voltage or ground potential to provide a reference potential for the applied voltage.

At its core, a rheostat is an adjustable resistor. It is composed of two wire leads with an adjustable knob and a sliding current contact that moves a resistance against a band. The resistance increases when the knob is rotated clockwise and decreases when the knob is rotated in the other direction. Rheostats are used in a range of electrical applications, from controlling the speed of motors to adjusting audio output.

When it comes to the 3851A-162-104BL, it is a three-terminal device in a leaded package. It is a low profile sealed, conductive plastic potentiometer, which is enclosed in a metal can. It is designed for use in applications which require ruggedness, durability, housing and protection against environmental hazards. It is also designed to provide a cost-effective but extremely reliable solution for various uses.

The 3851A-162-104BL has a multiturn adjustment. Its main application area is measuring mechanical displacement. It has a standard size package with a large range of resistance values from 0.1Ω to 20KΩ. It also has very low noise and high performance, with 0.1% resistance tolerance and 0.003% temperature coefficient.

The electrical working principle of the 3851A-162-104BL is based on a three-terminal resistive element. A wiper is connected to two of the terminals, and the third terminal is connected to a preset voltage or ground potential to provide a reference potential for the applied voltage. The resistance of the device is varied by turning the control knob, which moves the wiper along the resistive element.

The 3851A-162-104BL is designed for use in a wide variety of applications. It is ideal for use in motor control, audio output, voltage-controlled transistors and other electrical devices. It is also commonly used in radio and television receivers, wireless equipment, industrial automation, and medical equipment. Additionally, it is used in servo motors, position sensing and robotic applications.

The 3851A-162-104BL is a robust, reliable and cost-effective solution for various applications. It offers a variety of features, such as a high resistance range, a low profile package, and a reliable mechanical design. Its multiturn adjustment and robust prevention of environmental hazards make it an ideal solution for any application where resistance must be adjusted with precision and reliability.
