Waterproof connectors from FOD are intended to expand the design options when cabling small systems which will be used in harsh environments. A raised-body male terminal design provides polarisation to prevent accidental mis-mating. The watertight seal stopper and positive locks ensure secure mating retention. A cap lock system provides low terminal insertion force and high sealing performance. The spring-beam design affords high pressure and small deflection in high-vibration applications.
