3862C-282-103AL

Rotary Potentiometers (RPs), or also known as rheostats, are a type of position sensing device, which are widely used in various applications from electric motors to audio and visual control systems. The 3862C-282-103AL is a type of rotary potentiometer, which is designed for precision sensing. It features adjustable resistance values, durable construction and superior environmental protection, making it suitable for a variety of applications.

The 3862C-282-103AL is a 10-turn potentiometer with a rated operating temperature range from –20°C to 75°C. It provides a linear resistance track, and a total resistance range from 0.1Ω to 20KΩ. It has a panel mountable rear adjustment for variation in resistance. It is available in three versions – without switch, with momentary switch and with locking switch. This device works on the principle of a variable resistor, wherein a voltage or current is applied across the two terminals of a resistor, which further controls the current or voltage at the third terminal.

It is widely used in a number of applications such as motor drives, adjustable power supplies, industrial control systems, medical equipment, audio/visual equipment, robotic devices, and military equipment. These potentiometers can also be used as an adjustable circuitry for controlling the speed and position of DC motors. It has also been used in stage lighting control systems to adjust the light and brightness levels on stage. It is robust and durable, making it reliable in industrial environments.

The 3862C-282-103AL is constructed with an electrode, a resisting element and a rotation control. It consists of a plastic-molded housing, in which an electrode is connected to the center of a contact disk, representing the wiper. The resistor element is fit to the housing, and the contact disk is placed over it. The rotation control is attached to the resistor element and is connected to the wiper.

The principle of this variable resistor is based on two electrical properties – resistance and inductance. As the rotation control is rotated, the resistance between the wiper and any of the two fixed electrodes changes. When the resistance decreases, more current flows through the circuit, and vice versa. The amount of current flow depends upon the rotation of the control knob.

The 3862C-282-103AL is an ideal solution for applications requiring precise resistance control with low error rates. It has an adjustable resistance values and a durable construction, making it suitable for a variety of applications. With its superior environmental protection, it can withstand harsh industrial environments.
