Slide potentiometers are adjustable electrical resistors commonly used in electronics. From amplifiers to transducers, from volume adjustment to game controllers, potentiometers are used to provide variable resistance in a circuit. The PDV30-21M-104B is one of many slide potentiometers on the market today.

The PDV30-21M-104B is a linear rotary slide potentiometer, made up of a resistor element, a slider, a wiper, and a knob. It is 2.5” in length and has a total resistance of 21 kΩ before linear taper. The maximum power rating is 0.5 W at 70° Celsius, and the maximum rotational angle is 300 degrees. The terminal type is a 2- to 4-pole miniature terminal block, and the max insulation resistance is 1 G Ohm.

The primary application of the PDV30-21M-104B is in volume control in audio systems. When the user turns the knob on the PDV30-21M-104B, the wiper moves along the resistor element and adjusts the resistance within the circuit. This, in turn, changes the overall current in the circuit, which is interpreted by the amplifier as a change in volume.

The PDV30-21M-104B is also commonly used in audio mixing consoles and test instrumentation. The variable resistance enables the user to dial in precise amounts of voltage or current, depending on the device that’s being used. This allows for accurate measurements when calibrating sensitive devices.

In addition to volume control and precision calibration, the PDV30-21M-104B is also used in robotics. By connecting the potentiometer’s output to a microcontroller, the user can program a robot to accurately move and turn objects. The PDV30-21M-104B thus serves as a bridge between the human user and the robot, allowing the user to control the robot precisely and accurately.

The PDV30-21M-104B can also be used in game controllers, such as those for game consoles and PCs. The PDV30-21M-104B can be connected to the game controller’s circuitry, allowing the user to control the speed and direction of game objects.

The PDV30-21M-104B is used in many applications because of its adjustable resistance and precise movements. It can be used for volume control, precision calibration, robotics, and game controller applications. By connecting it to the proper circuitry, the user can create sophisticated devices that are accurately and precisely adjustable.
