Rotary Potentiometers and Rheostats are common components used in electronic measurement and control circuits. The 95A1A-B28-A20L is a rotary potentiometer/rheostat from the MECO Corporation. It is a potentiometer/rheostat with adjustable shaft and knurled knob for manual control, designed for various applications.

The 95A1A-B28-A20L is designed for potentiometer/rheostat applications such as controlling DC current, voltage, and power. It can be used as an adjustable voltage divider with a contact form protected by a plastic mount. The 95A1A-B28-A20L is a three-terminal device, with a central “potentiometer” terminal tied to and adjustable from the two end terminals. By controlling the amount of resistance between the two end terminals, the user is able to control the amount of power or voltage supplied to the central terminal.

In operation, the 95A1A-B28-A20L operates using the principle of AC and DC current flow. AC current flow utilizes the potentiometer’s resistance by transferring it from one terminal to another. As the angle of the shaft adjusts, the resistance between the terminals changes. The DC current flow operates similarly, but instead of the resistance changing, the current flow is adjusted. The 95A1A-B28-A20L’s adjustable shaft and knurled knob allow the user to accurately adjust the flow.

The 95A1A-B28-A20L is also designed to be able to withstand environmental conditions such as temperature, humidity and vibrations. It has an operating temperature range from 0°C to 70°C (-15°C to 85°C with an optional heatsink), a humidity of 80% at 40°C (non-condensing) and vibration of 20-50 Hz. These features make it an ideal component for outdoor use in conditions such as aircraft flight decks and off-shore drilling.

The 95A1A-B28-A20L is a robust component with a design that allows for precision setting. Its adjustable shaft and knurled knob allow for easy manual control, while its three terminal design allows it to be used for controlling DC current, voltage, and power. Its wide operating temperature range and other environmental protections make it suitable for outdoor use even in the most extreme conditions.
