Constructed as a 3 meter RG11 coaxial cable pair with pre-installed inline ferrite cores, the cable set establishes redundant physical layer links between network interface modules. The RG11 assembly maintains controlled characteristic impedance to minimize signal attenuation and high-frequency noise reflections across local control bus spans.\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\u003e51308112-003\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\u003e2.01 lbs (0.91 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eCable Length: 3 meters (9.84 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePassive Interconnect Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Specification\u003c\/td\u003e\n\u003ctd\u003eRG11 Coaxial with Inline Ferrite Cores\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSet Quantity\u003c\/td\u003e\n\u003ctd\u003eSet of 2 cables (Redundant Link Pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCore Application\u003c\/td\u003e\n\u003ctd\u003eConnecting Local Control Network (LCN) Nodes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Impedance\u003c\/td\u003e\n\u003ctd\u003e75 Ohm nominal\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 51308112-003 RG11 coaxial cable set utilizes heavy braid and foil shielding around each conductor to prevent RF interference and cross-talk between redundant LCN A and LCN B network channels. Integrated inline ferrite beads suppress common-mode electromagnetic noise and high-frequency voltage transients before signals reach transceiver electronics on the network interface cards. This physical and electrical isolation preserves low-error bit transmission across active control node connections.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can an individual cable in the 51308112-003 dual set be disconnected while the LCN network is operational?\u003c\/p\u003e\n\u003cp\u003eA: Disconnecting one cable breaks communication on that specific link channel (A or B), but the network maintains operational node connectivity via the secondary redundant cable.\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary purpose of the inline ferrite cores on this RG11 coaxial assembly?\u003c\/p\u003e\n\u003cp\u003eA: The ferrite cores act as high-frequency chokes to attenuate common-mode noise and electromagnetic interference picked up along the 3 meter cable run.\u003c\/p\u003e\n\u003cp\u003eQ: What installation precautions prevent physical degradation of the RG11 coaxial cable structure?\u003c\/p\u003e\n\u003cp\u003eA: Maintain the manufacturer specified minimum bend radius during cabinet routing to avoid deforming the dielectric core or damaging the outer shield braid.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the 3 meter cable jacket, BNC\/F-type connectors, and ferrite modules for physical damage before installation.\u003c\/li\u003e\n\u003cli\u003eRoute Link A and Link B coaxial cables through distinct cabinet paths to preserve physical redundancy and prevent concurrent mechanical damage.\u003c\/li\u003e\n\u003cli\u003eAlign the coaxial connectors with the LCN node interface ports and twist to lock firmly into position.\u003c\/li\u003e\n\u003cli\u003eEnsure connector shield shells establish full 360-degree contact with the mating jack for ground continuity.\u003c\/li\u003e\n\u003cli\u003eAvoid overtightening or sharp bends near the connector terminations to prevent internal impedance mismatches.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53621187674421,"sku":"51308112-003","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/51308112-003.png?v=1789972641","url":"https:\/\/www.5gplc.com\/products\/honeywell-51308112-003-coaxial-cable-assembly","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
