Rotary potentiometers and rheostats are both two-terminal electronic devices for controlling the current or voltage in an electronic circuit ¹. The 3-1624200-9 is a type of rotary potentiometer or rheostat that utilizes a wirewound element for variable resistance. It is characterized by its long life and good noise and vibration characteristics.

The 3-1624200-9 is a "multi-turn" potentiometer, meaning that the resistance of the device increases proportional to the number of rotations or turns of the shaft. This provide the user with a greater range of precision control than a single-turn potentiometer. The device has a built-in vernier scale for fine-tuning the adjustment.

The 3-1624200-9 can be used in a wide range of applications, including industrial, medical, automotive, and aerospace control systems. In each case, it can be used to control the resistance of an electric circuit, allowing the user to adjust the amount of current or voltage present in the circuit.

The 3-1624200-9 is also designed to resist extreme environmental conditions. Its durable construction features a housing constructed from die-cast aluminum alloy with a black zinc finish. This construction resist corrosion and helps protect the internal electronic components from damage.

The working principle of the 3-1624200-9 is relatively simple: when the user turns the knob on the device, the internal resistance of the device changes. This, in turn, changes the current or voltage flowing through the circuit.

At its core, the 3-1624200-9 is a potentiometer, or variable resistor. Potentiometers contain a resistive strip, which is typically made of carbon or graphite, and which can be adjusted by turning the knob on the device. Turning the knob causes the contacts on the resistor to move, which results in a change in resistance.

In the case of the 3-1624200-9, the resistance is adjusted by moving a wirewound element which is connected to the knob. As the knob is turned, the wirewound element moves in a helical (spiral) manner to increase or decrease the resistance of the device. This motion is much smoother and more precise than the linear motion of a carbon strip typically used in potentiometers.

The 3-1624200-9 is an excellent choice for many types of applications where precise control is needed. Its long life and resistance to vibration and noise are major advantages, as is its ability to accurately respond to multiple turns of the knob. The device is also designed for use in extreme environmental conditions, making it a reliable choice for many industrial and aerospace projects.
