3851A-202-104BL

Rotary Potentiometers and Rheostats are two of the most commonly used devices in the industry today. Used in a variety of applications, they are widely used to adjust voltage, current, temperature, and/or pressure measurements. The 3851A-202-104BL is an example of such a device, which is used in applications such as audio and video equipment, communications equipment, and instrumentation.

The 3851A-202-104BL is a two-terminal device with a maximum power rating of 2 watts, a maximum voltage rating of 50 volts, and a continuous current rating of 3 amps. It is typically supplied in a 0.22-3.7 ohm resistance range, and is typically used as an adjustable voltage divider or a variable resistance element. It is often used to precisely control the voltage and current in circuits.

The device consists of a hollow metal cavity containing an internal rotating helix. A voltage is applied across the terminals of the internal helix and the internal rotary lever, causing a change in resistance. As the lever is turned, the rotary helix rotates which changes the resistance between the terminals, thus allowing for precise voltage and current control. The resistance between the two terminals can be adjusted with up to 0.1 mV accuracy.

The device can be used in a wide range of applications, such as audio and video equipment, communication and instrumentation systems, and devices that require precise voltage and current control. It is often used to adjust gain, volume, frequency, and power in many of these applications, and it is particularly suitable for use in musical instruments and loudspeakers.

The 3851A-202-104BL is also commonly used in industrial automation applications, motor control, medical instrumentation, precision measurement and control, and robotics. In these applications, the resistance of the device can be used to precisely control the voltage and current across motors and other electrical components.

The 3851A-202-104BL is also used in many portable electronics applications. These typically include cell phones, digital cameras, camcorders, and portable audio players. The device is used to precisely adjust the voltage and current across components in these devices, allowing for precise control of the audio and video signals. It is also used to control the brightness of LCD and LED screens in these devices.

To conclude, the 3851A-202-104BL is a great example of a rotary potentiometer or rheostat. With its two terminals, it is able to precisely control the voltage and current across its terminals, making it a great choice for many applications. It is particularly suitable for use in precision measurement and control, audio and video equipment, and portable electronics applications.
