The IP67 waterproof Vents clip into enclosures, allowing air to flow through the membrane without letting dust or water ingress. Technicians were concerned about pressure build-up inside the enclosures due to changes in temperature which create differences in pressure; this pressure build-up can ultimately damage the seals of the enclosure, leading to failure of the sealed enclosure.
"The Vent will allow this pressure difference to equalize inside with outside," says the company. "It also reduces condensation build-up by allowing moisture to escape out of the sealed enclosure."
Richard Redding of Selectronix commented: "The engineers chose to install multiple vents, to enable heat to escape out of the enclosure; whilst that is not the purpose of the vents, inevitably with multiple vents installed, warm air was able to escape out of the sealed unit".
The one-piece plastic IP67 Vents are quick to install - simply clicking into a hole in the enclosure wall, creating a watertight seal. Manufactured by Nitto Denko in Japan, Vent applications include: car engine management systems (ECUs), outdoor lighting, outdoor wireless communications enclosures - "basically any outdoor electronics housed in a sealed enclosure," the company adds.
Selectronix is the UK distributor for Nitto Denko Vents and specialize in harsh environment connectors and enclosures.
