ST12 Pintail connectors can build an indoor/outdoor interconnect system that offers the performance and reliability of MIL threaded connectors at the cost of a commercial (COTS) product. The ST12 (rear panel mount hole size 12mm/front panel mount hole size 14mm) series of multi-pin, threaded coupling connectors will provide IP67 integrity when mated and will work reliably indoors and outdoors where occasional submersion is encountered at a limited depth. It will also remain undamaged by the formation of ice on the enclosure and will resist corrosion.
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. IP67 is intended for applications that will get ‘rained on’, or occasionally washed/drenched. 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).
