Toyota case study powertrain

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.

GORE® Vents provide life-of-vehicle protection to maintain the reliability of lighting systems that support vehicle differentiation and functionalities — for example, in EVs where thinner modular lamps can illuminate brand signatures and integrate new sensing/communication devices.

Reduce Condensation

Technical Information

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.

This document provides performance characteristics and specifications for GORE® Automotive Vents AVS 22 and AVS 23, suitable for rear lamps. Featuring a laminate construction, these low-profile adhesive vents provide a secure bond to the housing.

NEMA Ratings and What They Mean

Technical Information

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.
