Pressure Relief Vents

Amphenol LTW Pressure Relief Vents equalize the pressure inside and outside sealed enclosures and prevent heat dissipation of electronic components from shortening devices' service life and affecting performances. These vents facilitate controlled pressure release within safe operating limits and are designed to equalize external and internal pressure. This prevents heat accumulation from electronic components and reduces the need for bulkier housings and seals. The vents are built with hydrophobic/oleophobic membranes and offer IP68/IP69K ingress protection to keep out liquids, oils, and moisture while reducing condensation in sealed enclosures. Amphenol LTW Pressure Relief Vents are available in protective metallic, plastic, or stainless steel and maintain integrity amid extreme changes in pressure. Applications include industrial/farm automation, outdoor broadband wireless access, LED lighting, IP closed-circuit TV/security, renewable energy, marine electronics, and hybrid electric vehicles.
