Slide Potentiometers are broadly used in a number of industrial, automation, and automotive applications. The PTA2043-2010CIA104 is a popular slide potentiometer that is designed for precision, reliability, and long-term stability. The device features a recessed total range of 100mm and utilizes a two-piece assembling featuring a linear black scale. The major components are a printed circuit board, an electronic board, a potentiometer cover, and a black scale.

The linearity of the device is up to 0.75%, and it has a resolution of 500 points per inch with a 77mm travel. The device is also equipped with long travel stability and hardness, contact pressure, temperature stability, and low noise output. Furthermore, the potentiometer has a signal range of 0-100%, a 24V DC voltage rating, and a power rating of 2W. The device operates in the temperature range of -40°C to + 85°C.

The primary working principle of the PTA2043-2010CIA104 slide potentiometer is based on a resistive divider. The voltage drop across the resistive track is determined by the contact position and varies as a function of the voltage applied to the potentiometer. In this configuration, a sliding contact position on the resistive track determines the voltage output. The device is also comprised of two or three terminals. The terminal connected to the resistive track is VCC, which is the supply voltage, while the other end of the potentiometer is connected to ground through a voltage sense resistor.

Using the non-conductive slide films, the PTA2043-2010CIA104 slide potentiometer is capable of maintaining clean contact surfaces for high accuracy. The contact surface is constructed from special matte carbon steel film, which offers superior resistance to wear and abrasion. The contact surfaces are slightly curved to facilitate wiping action which in turn minimizes the contact resistance drift due to oxidation or wear.

The slider contacts are made from highly durable electro depression alloys which exhibit excellent surface hardness and high-temperature stability. The slider contacts are gold-plated to enable low contact resistance and high contact reliability over a long period of time. The PTA2043-2010CIA104 is also coated with protective film for improved anti-corrosion performance.

This device also incorporates a movable power switching feature which allows the potentiometer to be quickly disabled when the contact position reaches an end limit. This helps prevent overstressing of the slider contact, reduces power usage, and ensures long-term accuracy as required in automation applications.

In conclusion, the PTA2043-2010CIA104 is an advanced version of slide potentiometer designed to meet the need of the most demanding applications. Its recessed range of 100mm, long-term stability, and accuracy make it an ideal choice for automotive, industrial, and automation applications. Its durable contact surfaces and protective film coating, low noise output, and movable power switching feature further ensure reliable performance.
