IP68 "Pintail" Plastic Circular Connectors The Pintail connector range provides low-cost, weathertight standard interconnection for industrial and marine applications.

Pintail connectors 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 SP13 (front panel mounting hole size 13mm) and SP21 (front panel mounting hole size 21mm) series of multi-pin, threaded coupling connectors will provide IP68 integrity when mated ("Ingress of water in quantities causing harmful effects shall not be possible when the product is continuously immersed in water under conditions which shall be agreed between the manufacturer and the user") and will work reliably indoors, outdoors and in harsh UV and hostile wet environments. They are widely used for safe control and power connections between equipment where IP68 is critical, e.g. in instrumentation, process control, industrial machinery, automotive, marine and other applications like outdoor lights, LED lights and LED display walls, outdoor security cameras, etc.

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. The dual "O" rings (see above picture) mean that the integral backshell can be easily removed to allow accurate soldering of the incoming cable (see below).

Connector end caps are available to suit and IP68 integrity is achieved when male and female connectors are mated or when the IP68 end cap replaces a mating connector.

The stamped and formed solder terminations (screw machined brass on the SP21 range) are plated gold over nickel in cable free plug, in-line cable receptacle and front 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.

The front panel fixing SP2113 has the same panel cut-out and elliptical 2 hole fixing (hole size 22mm) as Amphenol C16-1 and Binder 693 type receptacles. The SP2113 will not mate with Amphenol C16-1 and Binder 693 (for that see Series WA22), but a mated pair of Pintail SP21 can replace them and provide IP68 rating. Plug and receptacle housings are keyed to ensure correct polarisation and tactile feedback when mating. Unlike many competitors' products all the Pintail SP13/21 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 glass filled nylon, flammability rated V-0 shells 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 -40 to 85 degrees C. They are RoHS compliant, CE approved, small, lightweight and extremely cost-effective when compared to their metal counterparts ~ without compromising the integrity of the interconnection.

Pintail connectors are designed for at least 500 mating cycles and can accommodate cable diameters from 3 to 12mm.
