New vent with smaller-footprint for automotive electronic housings
W. L. Gore & Associates, Inc. has introduced new venting for automotive electronic housings.
About 30% smaller than the PolyVent Snap-Fit product family, the new Compact Series is easier to integrate into small housings. It provides a higher level of protection for sensitive components like sensors, motors and control units, while providing reliable and rapid pressure equalization.
The company claims the combination of protection and pressure equalisation is due to an enhanced microporous GORE membrane that breathes to allow airflow, while blocking entry of water and contaminants.
The PolyVent Compact Series' smaller dimensions allow for more design options and smaller, lighter weight housings. The smaller vent diameter (only 14.3 mm) makes the PolyVent Compact Series easier to integrate especially when the installed housing has very limited clearances.
Low installed height (only 3.45 mm) affords less external protrusion and less vulnerability to mechanical impacts or steam-jets. Often, no protective wall is needed, so housing design is simplified, development is less costly, and the enclosure more readily fits into the tightest under-hood spaces. And the smaller total vent height (only 8.9 mm) provides more flexibility in component layout, and facilitates heat transfer from printed circuit boards to the housing exterior.
The company says the new series provides advanced levels of protection which will extend the reliability and service life of sensitive electronic components. An enhanced oleophobic membrane design provides about 30% better WEP (Water Entry Pressure) resistance, with the same airflow and chemical resistance as the previous series.
In addition, the GORE PolyVent Compact Series uses the same advanced PolyVent materials technology "“ such as a hydrostabilized PBT GF30 vent body and silicone O-ring construction "“ that has been proven reliable in automotive applications worldwide.
