Constructed in a 1 x male plug to 2 x female jack configuration, the passive adapter splits or taps high-frequency serial communication and coaxial signal lines without altering transmission line characteristics. The metallic shell provides full 360-degree shield continuity across all three interface ports to suppress radio frequency interference and signal reflections.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e51190728-105\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.03 lbs (0.014 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard BNC Male-to-Dual-Female Profile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePassive Component\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdapter Interface\u003c\/td\u003e\n\u003ctd\u003e1 x BNC Male Plug to 2 x BNC Female Jacks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Impedance\u003c\/td\u003e\n\u003ctd\u003e50\/75 Ohm Coaxial Networks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eBNC Tee Adapter Connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eNickel-plated brass with gold-plated pin contacts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe 51190728-105 maintains grounded conductive shielding across its 3-way junction to preserve channel-to-channel isolation between adjacent signal taps and external high-voltage field wiring. High-density metallic outer housing shields high-speed coaxial data transfers against external electromagnetic noise and cross-talk. When integrated into dual-redundant coaxial bus lines, the low-impedance grounding shell prevents stray voltage transients from degrading signal-to-noise ratios across field processing nodes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 51190728-105 BNC Tee Adapter be installed or removed while the coaxial network is actively transmitting data?\u003c\/p\u003e\n\u003cp\u003eA: Disconnecting the adapter opens the coaxial transmission line, causing impedance mismatch, signal reflections, and potential node communication drops on that specific bus segment.\u003c\/p\u003e\n\u003cp\u003eQ: What function does the male plug to dual female jack layout provide on a coaxial bus node?\u003c\/p\u003e\n\u003cp\u003eA: The male connector attaches directly to the processor transceiver port, while the two female jacks allow in-and-out loop wiring of coaxial trunk cables with line termination resistors.\u003c\/p\u003e\n\u003cp\u003eQ: How is chassis ground continuity maintained through the adapter?\u003c\/p\u003e\n\u003cp\u003eA: The bayonet locking mechanism mechanically clamps the nickel-plated outer shell to the mating connector, establishing a low-resistance chassis ground path.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect male and female BNC bayonet pins, dielectric insulators, and center contacts for corrosion or physical deformation prior to mounting.\u003c\/li\u003e\n\u003cli\u003eAlign the bayonet slots of the 51190728-105 male plug with the receptacle lugs on the node card faceplate and push firmly while twisting to lock.\u003c\/li\u003e\n\u003cli\u003eConnect incoming and outgoing coaxial cables to the two female BNC jacks, ensuring both bayonet locks fully snap into position.\u003c\/li\u003e\n\u003cli\u003eVerify that bus termination resistors (50 Ohm or 75 Ohm as specified by network architecture) are fitted to open female ports at the physical ends of the cable run.\u003c\/li\u003e\n\u003cli\u003eAvoid applying excessive side-loading mechanical stress to the adapter body when routing rigid coaxial cables through cabinet wireways.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53621206876469,"sku":"51190728-105","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/51190728-105.png?v=1789973092","url":"https:\/\/www.5gplc.com\/products\/honeywell-51190728-105-bnc-tee-adapter","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
