"The air passes through, but water and dust do not." ■Specifications of the VGA Series Waterproof Exhaust Protection Plug - In a sealed enclosure, temperature and pressure differences between the inside and outside can cause condensation. - The VGA exhaust plug (VGA series) suppresses the occurrence of condensation by adjusting temperature and pressure differences. ■Features and Principles of Air Intake and Exhaust - The pore diameter of the membrane part of the VGA exhaust plug is approximately 0.3 to 0.5 μm, while water vapor is 0.0004 μm, rain is 2,000 μm, and drizzle is 1,000 μm, allowing for the discharge of humidity inside the enclosure while also being waterproof. - Air that expands due to temperature rise inside the enclosure passes through the filter due to pressure differences, adjusting the pressure inside the enclosure. - The VGA exhaust plug exhibits excellent protective performance against temperature and humidity influences.

basic information
■Mounting Part ISO/Metric Screw (EN60423) ■Material Main Body & Protective Cap / 66 Nylon (UL94V-2), Washer & Seal / EPDM Membrane / ePTFE (Foamed Polytetrafluoroethylene), Protective Film / PET ■Color Black (RAL9005) & Gray (RAL7035) ■IP Rating IP68 ■Operating Temperature Range -40℃ to 105℃ (Momentary/1 minute: 160℃) ■Features Prevents the intrusion of water, oil, and dust from the outside, while maintaining ventilation with the outside to suppress condensation inside the enclosure and prevent leakage issues due to pressure increase. In the case of submersion specifications, a water film forms on the surface, preventing water vapor from passing through, which can lead to moisture buildup, so caution is required.

Applications/Examples of results
- The VGA exhaust plug can be used in products such as lighting fixtures, connection boxes, and operation boxes. It is particularly suitable for outdoor applications. - For example, streetlights that require high waterproof performance are sealed, which can cause hot air to accumulate inside the lighting fixture and lead to condensation. By installing the VGA exhaust plug, it is possible to address the issue of condensation, which can cause malfunctions in various circuit board components. *For physical data, usage frequency, installation locations, and other details such as pricing, please download the PDF or feel free to contact us.
