Micro Twinax/Quadrax connecTors High Speed Fiber Optics Single and Multimode ► Micro twinax vailable in threaded, quick disconnect, sMa and Micro-D size packages ► 25% smaller in diameter than sMa coaxial connectors ► controlled impedance with tightly spaced Pcb footprint spacing. Smiths Connectors Sabritec’s Micro Twinax NDL line features matched impedance miniaturized connectors that provide the user with controlled impedance and tightly spaced PCB footprint spacing. The NDL Micro Twinax Series is offered in threaded and quick disconnect styles and are 25% smaller in diameter than SMa coaxial connectors. The quick disconnect version has a diameter of .250" max and the threaded version has .250" hex coupling nut. Micro Quadrax connectors are designed for differential pair matched impedance applications utilizing quadrax cable consisting of four wires where the diagonal pair of conductors forms a differential twinax pair. These connectors maintain the signal to shield impedance throughout the mated connector pair (quad conﬁ guration applications exceeding 1 Gbit/sec) and are available in threaded versions including straight and right angle PCB mount conﬁ gurations. Micro Twinax and Quadrax connectors have a low impedance ground shield and are ideal for high-Speed ethernet (100 and 1000 Base-T), Fibre Channel (>1 Gbits/sec), Ieee 1394 Firewire, USB, DVI and Inﬁ niband applications with 100 or 150 Ohm differential pair impedance. ► MechanicaL & enVironMentaL sPeciFications temperature rating: -55˚C to + 125˚C corrosion: MIL-STD-202 Method 101 Test Condition B shock: MIL-STD-202 Method 213 Test Condition B Vibration: MIL-STD-202 Method 204 Test Condition B thermal shock: MIL-STD-202 Method 107 Test Condition B Durability: 500 Mate/Unmate cycles min. coupling nut torque (threaded) recommended: 2.3 in-lbs min.
