KKA5041S28

Rotary Potentiometers, Rheostats, have several applications, which include measuring position and speed, controlling air flow, electrical circuits, and audio and video signal level applications. The KKA5041S28 is a rotary potentiometer with an output voltage of 0-5V DC and a sensitivity range of 0-10V DC. The device is specifically designed for speed sensing and signal conditioning applications.

The KKA5041S28 consists of a wiper shaft and resistive element. The shaft is mounted on a base and is connected to the spindle at the center of the base. The shaft is rotatable within a range of 0-90 degrees. The resistive element consists of a single beam of conductive material, running along the length of the base. Each end of the beam is connected to a pair of terminals, labeled as “A” and “B”. As the wiper shaft rotates, the wiper arm sweeps across the resistive element, generating a signal voltage between the “A” and “B” terminals that is proportional to the angle of the shaft.

The working principle of the KKA5041S28 is based on voltage divider circuit. As the shaft rotates, the wiper arm encounters different sections of the resistive element, and thus divide the source voltage (Vin) into two voltages. The voltage drop across the wiper arm (Vw) is equal to the voltage across the remainder of the resistive element (Vr). Since Vw is proportional to the angle of the shaft, and Vr is fixed, the output voltage (Vout) can be easily calculated from the two voltages: Vout = Vin (Vw/Vr).

The KKA5041S28 is well suited for measuring angular position and speed, as well as controlling electrical circuits. It can be used in air flow or signal level applications, as well as industrial and automotive applications, where accurate sensing of speed or position is needed. With a two-terminal input and two-terminal output, it provides an efficient way of controlling circuits or monitoring signals without the need for complicated wiring schemes.

In addition, the KKA5041S28 is design for temperature compensation. Thus, the output voltage does not vary significantly with temperature change, which helps to maintain a high degree of accuracy over a wide temperature range. It is also highly reliable and easy to use, helping to make it an ideal choice for applications where accuracy and reliable performance are critical
