Completely submersible micro-connector for underwater electrical installations

Hylec-APL has launched the new TeePlug TH381 plug and socket electrical micro connector designed for underwater use and harsh environment installations.  Offering the highest levels of reliability, the connectors provide complete protection against the effects of permanent submersion in water to ensure electrical connection, even when subjected to high pressure water jets.  The IP68/IP69K rated models also prevent dust and dirt ingress.  Measuring only 14mm in diameter, the series suits outdoor lighting applications, such as architectural lighting, street lighting, underwater lighting, illumination of road signs and billboards and the connection of interior and exterior Class 2 electrical devices.   The connectors feature a push-pull design that installs up to 80% faster than competitive waterproof connectors, saving valuable time on-site and reducing cost. Intuitive and functional in use, connectors incorporate a special coupling system that confirms correct alignment and mating with an audible click and also prevents accidental disconnection, even against opposing forces of 25kg (8Kg according to EN61535).  Models with an additional optional safety system are available to further protect against disconnection by requiring the use of a tool such as a flat-blade screwdriver for uncoupling.   The TH381’s IP68 water resistance rating is guaranteed even when subjected to bending forces of up to 5Kg, and they are resistant to high pressure water jets up to 100Br, 16l/min at a water temperature of 80C.   Vibration and external mechanical stresses are no problem either, as cable traction is prevented up to a force of 8Kg.   Electrical specification is two-poles, 10A – 400V AC/DC.  Wire section is 0.25mm² to 1.5mm² without ferrules.  The plugs and sockets are available in two variants, cable to cable and panel-mount, and in two sizes to suit cable diameters between 5.8mm and 6.9mm and 7mm–8mm. Cable reduction grommets are available for smaller cables, as are additional accessories, including sealing caps, a dedicated spanner for quick, safe installation, a bigger cable gland for larger cables and a rear nut for panel-mounted installations.
