Slide Potentiometers

Slide Potentiometers are potentiometers which feature a movable slider element and are designed to provide a variable resistance suitable for use as a voltage divider. The potentiometer, also known as a pot, is an electronic component used to adjust the current flow in an electrical circuit by varying the resistance of the sliding element. This simple device is used to control a variety of functions, such as volume, gain, brightness, or other variables in electronic devices.

EWA-MP9U20B35 Application Field

The EWA-MP9U20B35 is a compact, low-cost, programmable slide potentiometer designed for numerous applications, ranging from consumer electronics through instrumentation and and industrial control. It is widely used to adjust the volume, brightness, and other adjustable parameters in common consumer products, such as CD players, MP3 players, mobile phones, and cameras. It can also be found in more advanced applications such as instrumentation, process control, industrial control systems, and medical equipment such as X-ray machines, ultrasound systems, and other imaging equipment.

EWA-MP9U20B35 Working Principle

The EWA-MP9U20B35 is a 3-terminal slide potentiometer with a single sliding element. The resistance between the terminals varies as the slider is moved, with a maximum resistance of 20KΩ. The slider is controlled by a Micro-Slide-Track (MST) technology which provides superior repeatability and accuracy when compared to other techniques. The EWA-MP9U20B35 is pre-calibrated for 20KΩ resistance and designed to operate from -40°C to 85°C with an input voltage of 5V maximum. It has a rated working life of 1 million cycles and is available in both Linear and Logarithmic configurations.

The EWA-MP9U20B35 works by using the MST technology to send a signal from the slider to the terminals as it is moved. This signal causes the resistance between the terminals to change, depending on the position of the slider, which makes it useful for creating a variable voltage divider circuit. This variable voltage divider is then used to control a variety of functions in electronic devices, from volume control to fan speed.

Conclusion

The EWA-MP9U20B35 slide potentiometer is an incredibly useful and versatile device that can be used in a wide range of applications, from basic consumer electronics to more advanced industrial and medical applications. It is a low-cost, pre-calibrated, programmable device that is designed to provide an adjustable resistance suitable for use as a voltage divider in order to control a variety of functions in electronic devices. Its Micro-Slide-Track technology provides superior repeatability and accuracy compared to other techniques, and its long working life ensures it can be used for many years to come.
