The SF12 IP67 has a self catching system which is renowned for its easy and quick mating and unmating features. This unique, easy to use, push-pull locking system, reduces the time taken to achieve a robust, waterproof IP67 seal by a factor of up to 10 times compared to a traditional screw-thread mechanism. It also provides security against vibration, shock or pull on the cable and facilitates operation in a very limited space. The push and pull system also allows the connector to be mated by simply pushing the plug axially into the socket. Once firmly latched, connection cannot be broken by pulling on the cable. When required, the connector is disengaged by a single axial pull on the outer release sleeve. It first disengages the latches and then withdraws the plug from the socket.
The IP standard describes a system for classifying the degrees of protection provided by the enclosures of electrical equipment. Developed by the European Committee for Electrotechnical Standardization (CENELEC), these standards are designed to numerically rate an electrical product on the level of protection its enclosure provides. IP67 connectors must allow no ingress of dust with complete protection against contact. They are not intended for use under continuous pressure. In consideration of the broad range of ‘rained on’ definitions, the industry appears to have agreed to a ‘test of immersion for 30 minutes, at a depth of 1 metre, or the equivalent air test at 1.45 psi. That is the Qualification Test. (Protected against the effects of temporary immersion between 15cm and 1metre. Duration of test 30minutes).
Using a combination of O ring sealing, high temperature 260 degrees inserts, grommets and compression nuts; the insulators and contact areas in these connectors are sealed against environmental elements. The “O” ring is sited so that the integral backshell can be easily removed to allow accurate soldering of the incoming cable. Connector end caps are available to suit and IP67 integrity is achieved when male and female connectors are mated or when the IP67 end cap is fitted to the IP67 socket body.
