51CAD-E24-D20L

Rotary Potentiometers, Rheostats

51CAD-E24-D20L is a type of rotary potentiometer, or rotary voltage divider, that consists of a three-terminal resistive element with a sliding contact that forms an adjustable voltage divider. This use of the device allows a\user to selectively set an output voltage that is a fraction of the input voltage.

Application Field

The 51CAD-E24-D20L can be used in many types of applications. In the consumer electronics industry, it is often used to control the volume and other settings of television, radios, stereos, and other audio equipment. It is also used to control the power settings and other features of ovens, microwaves, and other household appliances. In industrial applications, the 51CAD-E24-D20L can be used to control the speed of motors, the temperature of process streams, and the level of liquid in tanks.

Working Principle

The working principle for the 51CAD-E24-D20L is based on the adjustable voltage divider that is formed by the three-terminal resistive element and the sliding contact. It has two ends, an input end and an output end, where the output end is the adjustable end. When the sliding contact, which is also referred to as the wiper, is moved from one end to the other, it divides the input voltage into two parts, and the output voltage is the fraction of the input voltage that is determined by the position of the wiper.

The 51CAD-E24-D20L utilizes a resistor that has a low resistance at the input end and a high resistance at the output end. This enables it to produce a linear output voltage variation that is proportional to the position of the wiper. The resistance in the resistive element of the 51CAD-E24-D20L has a range of 40 to 500 ohms and the output voltage can range from 0 to 33 volts.
