Is Your Helmet Compatible?
Our flight helmet adapters are compatible with many helmets that use a Nexus U-174 connector. There are 2 common wiring standards for this connector. Our adapters use the Peltor wiring standard for this connector which is also compatible with NATO / UK (most civilian hellicopter flight helmets in the US use this standard), however there are some flight helments that use the NATO / US wiring standard for this connector. There are some slight differences in the NATO / US and NATO / UK connectors (pictured below) that will help you determine which connector your helmet has.
This is a compatible Connector.
This is also a compatible connector, but not when wired to US military standards; however, many companies wire this connector to the Peltor standard. Some companies will even wire this connector to either standard based on customer preference.
While we can help you determine which connector you have, it is impossible for us to know exactly which wiring standard was used. While the vast majority of US civilian flight helmets are compatible, if you are still unsure, often you can find out from the manufacturer of your helmet which wiring standard was used.
What connector does this adapter use? Nexus PTT (M9177/5-1 U-94A/U)
What wiring standard was the Nexus plug wired to? Our adapters are wired to Peltor or "Helicopter" standard.
Which Mic does the helmet need to have for proper usage? The adapter is designed to work with a civilian standard mic.
