Slide Potentiometers

Application Field

The PTA3043-2015DPB104 slide potentiometer is an adjustable device designed to help measure voltage or position using a non-contact, mechanical method. It is used in applications where precision and repeatability are important, such as in laboratory testing, medical equipment, and instrumentation. It is also used in motion control for machines and robotics.Slide potentiometers vary the resistance in a circuit which is then read by an electronic device. This method ensures accurate readings without the need for contact with the moving portion. A slide potentiometer consists of a larger fixed contact and a smaller, sliding contact. As the slide is moved, the resistance is changed, which can be monitored and read by an electronic device.

Working Principle

Slide potentiometers work using an electrical resistance process. When a current is passed through a potentiometer, the resistance changes depending on the position of the sliding contact. As the slide moves along the track, it increases resistance along one side of the track and decreases resistance along the other side. The ratio of resistance across the entire track is directly proportional to the position of the slider on the track.This resistance is then used to control the strength of an electrical signal, such as voltage or current. For example, in a lighting control system, the track can be calibrated to allow the user to adjust the brightness of the light. As the slider is moved, the resistance of the circuit changes, causing the current to increase or decrease, thus changing the brightness of the light.The precision of a slide potentiometer is affected by a number of factors, including track material, lead length, and resolution. Tracks can be manufactured from a variety of materials, including stainless steel, brass, plastic, and ceramics. To ensure accuracy, the track should be milled or laser-cut for maximum consistency. The lead length should also be kept as short as possible to minimize inductance, which can affect accuracy. Finally, the resolution of the potentiometer should be chosen based on the required accuracy.
