Trimmer potentiometers, also known as presets, are used in applications which require variable resistance. An EVM-AAGA00B55 trimmer potentiometer is a miniaturized version of a standard multi-turn trimmer. It is designed for high accuracy, with a wide resistance range from 10 ohms to 100 kohms, and switchable contact damping.

Features

The EVM-AAGA00B55 trimmer features a variety of features which make it a popular choice for high-precision applications. It has a wide resistance range which makes it suitable for a wide range of applications. It also has a switchable contact damping feature which reduces contact bouncing, providing stable operation at higher speeds, while remaining mechanically stable over time. Additionally, the body is made of corrosion-resistant stainless steel, and it is sealed to IP67 standards, making it well protected from dust, moisture, and other environmental elements.

Applications

The EVM-AAGA00B55 is used in a variety of applications including medical devices, industrial controls, communication devices, home automation, musical instruments, and automotive systems. In particular, it is often used in medical devices such as ventilators, incubators, and patient monitors, due to its high accuracy and wide resistance range. Additionally, the switchable contact damping feature makes it suitable for industrial applications, such as crane and robotic systems, as well as communication devices, home automation systems, and other systems which require precise and stable operation.

Working Principle

The EVM-AAGA00B55 trimmer consists of an internal resistor element, a sliding contact which mechanically connects the resistor element to one side of a voltage or current, a terminal to which the other side of the voltage or current is connected, and a flat screwdriver or small hex key which is used to adjust the contact position. When the contact is moved, the internal resistance of the resistor element changes, adjusting the voltage or current passing through the system. The switchable contact damping feature adjusts the spring tension of the sliding contact, allowing for smoother operation. The switchable contact damping can be adjusted simply by flipping the switch.

Conclusion

EVM-AAGA00B55 trimmer potentiometers are a popular choice for high precision applications due to their wide resistance range, switchable contact damping feature, and stainless steel construction. These features make the EVM-AAGA00B55 suitable for a variety of applications, including medical devices, industrial controls, and communication devices. The EVM-AAGA00B55 works by adjusting the resistance of the internal resistor element using a sliding contact. The switchable contact damping feature provides smoother operation by adjusting the spring tension of the contact.
