Trimmer potentiometers are used to control the resistance in a variety of electronic devices, such as those used in the industrial, automotive, consumer, and medical fields. The 82MR200KLF is a type of trimmer potentiometer which may be used in these and many other applications. A brief discussion concerning the application field and working principle of the 82MR200KLF will be addressed in this article.

Trimmer potentiometers are small, self-contained rotary potentiometers. Like other resistive components, they serve as voltage dividers, producing a varied voltage output from a constant voltage input. However, unlike other resistive components, trimmer potentiometers are field adjustable, giving users a way to finely adjust the output voltage while the device is in use. The 82MR200KLF is great for applications that require customers to adjust potentiometers manually, or where frequent adjustments are needed in the field.

The 82MR200KLF is particularly well-suited for industrial and medical applications where space is limited. It features a low 6mm profile and a 1.0mm long thread, making it easy to incorporate into even the most space-restricted designs. Additionally, it is constructed with a sealed base material that prevents any dust or dirt particles from entering the interior of the pot and shortening its life span.

The 82MR200KLF is protected from miswiring by its screwdriver style shaft limit, which holds it securely to the printed circuit board. This makes it possible for emergency readjustment to take place without the need to remove the entire unit from the system, which is especially beneficial in medical and industrial-grade implementations. The 82MR200KLF is also exceptionally durable, with an operating life of up to one million cycles despite its small size.

The working principle of the 82MR200KLF is based on its unique rotary wiper technology. The wiper rotates around a circular array of contacts and tracks, which produces a variable voltage output from a constant voltage input. As the wiper passes over different contacts on its track, it is able to produce variations in voltage output, allowing users to adjust the voltage input to their desired level.

Unlike traditional rotary potentiometers, the 82MR200KLF does not have a physical contact between the resistive element and the wiper. Instead, the resistive element is made up of a thin film of meticulously placed conductive and non-conductive elements along its track. When a wiper passes over the contacts, it creates an electrostatic connection between the wiper and the resistive element, resulting in a variable voltage output.

In summary, the 82MR200KLF is an ideal trimmer potentiometer for applications that require flexibility and durability. Its low 6mm profile allows for easy implementation in space-restricted designs, while its screwdriver shaft limit ensures that no miswiring will occur during adjustments. Additionally, its rotary wiper technology offers excellent accuracy and reliability, with an operating life of up to one million cycles. All of these features make the 82MR200KLF a great choice for industrial and medical applications.
