Rugged-P-Mic is a passive microphone targeted at environments that require the utmost in environmental and electrical protection. It is available in several different frequency response ranges and two different levels of water resistance. It is packaged in a one piece aluminum casing with substantial mounting locations. All internal components are “potted” in a thermally conductive epoxy material guaranteeing long life and maximum durability.
