The connector accepts standard BNC plugs on both ends and locks via the bayonet twist mechanism common to all BNC connectors.\u003c\/p\u003e\n\u003cp\u003eUsed in CCTV installations where pre-made camera cables need extending, in AV setups where video patch cables require joining, and in any application where two BNC-terminated coaxial cables need coupling. The connector maintains 50-ohm or 75-ohm impedance depending on the cables used, though it's most commonly paired with 75-ohm RG59 or RG6 coaxial for analogue and HD-over-coax CCTV systems.\u003c\/p\u003e\n\u003cp\u003eThe body is machined from nickel-plated brass, giving corrosion resistance and reliable contact over repeated connections. At 32mm long and 9mm diameter, the coupler adds minimal bulk to a cable run and fits through standard cable grommets and conduit entries. The knurled centre section provides grip for finger-tightening the bayonet lock without tools.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.008\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_CAB-BNC_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat cable types does this connector work with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe coupler works with any coaxial cable terminated with a male BNC connector.
