ST12 IP67 Threaded coupling

ST12 IP67 Threaded couplingIP67 ST12 Threaded Coupling Metal Circular Connectors

The Pintail connector range provides low-cost, weathertight standard interconnection for industrial and marine applications.


Pintail connectors can build an indoor/outdoor interconnect system that offers the performance and reliability of MIL threadedST12 IP67 Threaded coupling 2connectors 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).

Using a combination of dual O ring sealing, high temperature PPS inserts, grommets and compression nuts, all insulator and contact areas in these connectors are fully sealed against environmental elements WHEN MATED. The dual "O" rings (see above picture) mean 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 replaces a mating connector.

ST12 IP67 threaded coupling 3The stamped and formed solder terminations are plated gold over nickel in cable free plug, in-line cable receptacle and front or rear loading jam nut panel mounting receptacle options all of which can be used in applications where moisture, high humidity, water or dust could be a problem.

Plug and receptacle housings are keyed to ensure correct polarisation and tactile feedback when mating. Unlike many competitors' products all the Pintail ST12 connectors have the option of male or female contacts in any body shell; plus the ability to join cables with cable-end plug and in-line receptacle models.

Constructed of black nickel plated zinc alloy with 260 degrees C inserts these connectors have very stable dielectric and insulating properties plus they provide good mechanical properties at their design temperatures of -25 to 85 degrees C. They are RoHS compliant, small, lightweight and extremely cost-effective when compared to their MIL-C counterparts ~ without compromising the integrity of the interconnection.

Pintail connectors are designed for at least 500 mating cycles and can accommodate cable diameters from 5 to 8mm.
