H-385-3 is a panel seal assembly designed for use with Bourns Model 3683 digital pushbutton precision potentiometers. It features a clear silicone elastomer boot for transparent viewing of numerals and a rigid black plastic frame with a matte finish to complement most front panels. The assembly provides protection against unwanted entry of rain, dust, grease, or oils through the front of the potentiometer. With an expected life of 100,000 actuations minimum and tear-resistant construction, it ensures long-term reliable performance. The H-385-3 is ideal for applications requiring environmental protection of precision potentiometers in industrial and instrumentation settings.
