Rotary Potentiometers, Rheostats

The model 5311R10KL.5ST is a rotary potentiometer and rheostat manufactured by RC Components, one of the premier manufacturers of these component types. This model is designed to be used in applications that require infinitely adjustable voltage and current control. It is perfect for applications that require either low voltage, low current, or both, and its low profile and light weight construction make it ideal for applications where space and weight are limited factors.

Application Field

The 5311R10KL.5ST model is designed to be used in a variety of applications. It is well-suited for use in precision electronic equipment, such as audio and video controls, as well as in commercial and industrial operations that require adjustable voltage and current control. It is particularly useful for operations that demand control over multiple devices from one control panel, eliminating the need for multiple, heavy duty rotary switches.

This model is also suitable for use in smaller-scale operations. Automobile shop mechanics can use the 5311R10KL.5ST to change engine idle speeds and calibrate fuel injection. Amateur radio operators can use this model to adjust amplifier gain and transmitter power levels, while electric fans and motors can be controlled using this potentiometer.

Working Principle

The 5311R10KL.5ST is a "wirewound" rotary potentiometer and rheostat. This means that the device contains a resistive element composed of a spiral of wire that is wrapped around a core material, typically a ceramic or plastic tube. As the knob is rotated, a wiper rotates around the element and makes contact with the wire at different points along its length, resulting in a variable resistor with an adjustable resistance. The resistance is measured in Ohms and is adjustable across its full range, depending on the position of the wiper.

The resistance range of the 5311R10KL.5ST model is 10K ohms, with a tolerance of 5% or better. The model also has an adjustable power rating of 0.5W. This is much higher than what is found in most commercial and industrial applications, making it suitable for high power applications such as laboratory and test equipment.

The 5311R10KL.5ST also features a simple and robust mounting system. It is designed to be mounted on a variety of surfaces – from metal and plastic to wood and MDF – and can also be mounted in a vertical or horizontal configuration. This makes it highly versatile and easy to use in many applications.
