CapLocks & PlugLocks

Amphenol Socapex CapLocks and PlugLocks are locking systems that prevent access to critical connectors by intrusion or human error. These are locking accessories for MIL-DTL-38999 series III, RJFTV, and USBFTV connectors. CapLocks are locking rings that allow a cap to lock onto a receptacle to secure the port access. Once locked, they can turn freely around a cap and prevent fingers from unlocking the cap. PlugLocks are locking rings that allow a plug to lock onto a receptacle to secure the plug-to-receptacle connection. These locks can turn freely once locked around the plug coupling unit, preventing fingers from unlocking the mated pair.
