The 51AAD-C28-GA0/300L is a sealed 1/2-inch (12.5 mm) square control potentiometer designed for reliable performance in various environments. This potentiometer utilizes a conductive plastic element with an audio taper, rated for 0.25 watts of power at 70°C. It is built for durability with a rotational life of 50,000 cycles and operates over a temperature range of +1 °C to +125 °C. The component is sealed to an IP64 rating, making it suitable for board washing processes, and features PC pin terminals for through-hole mounting. Its robust, sealed design makes it ideal for applications requiring manual adjustment in industrial controls, professional audio equipment, and other electronic devices where reliability and environmental resistance are key.
