It routes data packets bound for downstream interfaces, maintaining transmission velocity alignment across foundational control layers and industrial bus systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel-to-Channel Isolation and Electromagnetic Suppression:\u003c\/strong\u003e The assembly features molded anti-interference ferrites on each terminal end to damp high-frequency common-mode noise. This mechanical configuration blocks parasitic electrical fields from entering node transceivers, safeguarding logic paths and preserving physical isolation boundaries between redundant communication slots.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How do the integrated ferrites affect the transmission characteristics of the LCN network?\u003c\/p\u003e\n\u003cp\u003eA: The molded ferrites function as high-frequency inductive chokes. They increase impedance solely against transient electromagnetic interference (EMI) and radio frequency interference (RFI) without attenuating the baseband carrier signals of the 2.0 m data link.\u003c\/p\u003e\n\u003cp\u003eQ: Can this cable assembly be hot-plugged directly into an active LCN transceiver port?\u003c\/p\u003e\n\u003cp\u003eA: Yes. Because the cable is a passive physical component, it can be decoupled or connected without dropping node power. However, disconnecting an LCN cable will break that specific channel's network loop, triggering an immediate failover to the redundant coaxial line.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis Layout Alignment, Clearance Constraints, and Mechanical Seating:\u003c\/strong\u003e Thread the BNC connectors straight onto the workstation network board ports, turning clockwise until the pins snap firmly into the locking slots. Maintain a minimum bend radius constraint of 50 mm along the 2.0 m cable path to prevent dielectric deformation or internal shield fracture near the ferrite bodies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Separation, Wireway Constraints, and Shield Grounding:\u003c\/strong\u003e Route the dual LCN coaxial cables inside separate panel raceways isolated from high-potential AC lines or motor actuator leads. Grounding occurs automatically through the outer braid contacting the BNC bulkhead, shunting induced stray fields directly to the central chassis grounding bar.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45147351285875,"sku":"51308111-002","price":410.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-07-02_16-13-46_0695a513-38bf-41dd-91da-2b418dfeb93c.png?v=1782982727","url":"https:\/\/www.dcssupplier.com\/ar\/products\/honeywell-51308111-002-lcn-coaxial-cable","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
