As LED lighting proliferates in automotive applications, so does condensation. That’s because LED lamps’ heat source is at the rear of the assembly, making the lens area the cold spot where condensation forms most easily. Often with unpleasant results: foggy, cloudy or streaky lenses, and lamps that don’t shine as brightly as when they left the showroom. Condensation could also compromise integrated sensors or other electronic devices.

Learn why Toyota Motor Corporation chose to partner with GORE® Automotive Vents when other venting solutions could not meet Toyota’s performance requirements for a new e-axle containing lubricated gears and a higher-voltage e-motor. This Case Study outlines the associated challenges, solution and results — including an on-time product launch for Toyota.

A critical aspect of vent selection begins with defining the level of protection your application, device or housing requires.

IP ratings cannot be “converted” to NEMA ratings, since NEMA requires additional testing not included in IP. However, there are minimum NEMA ratings that will meet or exceed a given IP code.

Fluctuations in temperature create failures in electronic devices due to pressure differentials. Gore application engineers simulated a rapid heating and cooling cycle to understand the effects of pressure differentials. This document describes the test procedures and results.

This document explains the format and classification of Ingress Protection (IP) ratings, according to the IEC 60529 standards.

The key to choosing the appropriate membrane technology for a given application is understanding the environmental conditions and the surface tension of the fluids that the vent will encounter.
