The 40 mm diameter AS04004MR-N50-WP-R is the waterproof, high-temperature version of the popular AS04004MR-N50-R and is built with a silver-poly convex-capped-paper diaphragm, rubber surround, and a cupped spider. A Kapton? former reduces moving mass for high sensitivity. The frame encapsulates the magnetic motor for durability and drop resistance.
