Rotary Potentiometers, Rheostats

Rotary Potentiometers and Rheostats are electronic devices often used for making electrical circuits, and these two components are frequently used together. The main purpose of this article is to discuss the applications field and working principle of the 3590P-2-502L device.

The 3590P-2-502L is a fully sealed rotary potentiometer with a continuous 3590-style design. It is generally used in audio applications. The device features an 8-terminal design, which includes a special backstop terminal, an adjustable "plunger" and an adjustment screw to adjust resistance. It has a maximum resistance of 1k ohms and a center/side resistance of 500 ohms. The device is available in three linearity options, including standard law, balanced and logarithmic.

The device has an aluminum die-cast housing and shaft with a package that is suitable for humid environments. It is a fully sealed device with a self-contained lubrication system, making it suitable for outdoor and underwater use. This makes it well-suited for applications such as rain sensor and automatic window wiper control. It is also IP65-rated, meaning that it can tolerate dust and water jets. Other features include an adjustable detent force, adjustable mechanical stops and a long mechanical life.

The device works through the use of a resistive element connected to a contact system. As the user rotates the shaft of the device, the contact system moves across the resistive element, changing its resistance. Depending on the type of device, these changes may be linear, logarithmic, or variable. The device has a built-in limiting resistor, meaning that it limits the maximum voltage that can be applied to it, protecting the device from over-current and voltage surges.

In order to use the device, it must be connected to a power source. The user must then use the adjustable plunger and adjustment screw to adjust the resistance to the desired value. This resistance value will then be reflected in the output of the device. The output signals can then be used in various applications such as motor control, audio control, and more.

Overall, the 3590P-2-502L is a versatile device that can be used for a wide variety of applications. Its aluminum die-cast construction and long mechanical life make it suitable for outdoor and underwater use, and its IP65 rating makes it highly resistant to dust and water jets. The device can be used in conjunction with a variety of resistive devices, and its internal limiting resistor protects it from over-current and voltage surges.
