It is constructed with two pairs of 22 AWG stranded tinned copper (TC) conductors and insulated with FEP (fluorinated ethylene propylene), a material chosen for its thermal stability, low smoke characteristics, and resistance to chemicals and abrasion. Licensed electricians and low-voltage systems integrators typically install this cable in access control, security, and building automation projects where reliable RS485 signal integrity is required.\u003c\/p\u003e\u003cp\u003eThis cable is suited for use in commercial and institutional buildings where access control readers, panels, and controllers communicate over RS485 serial bus or OSDP (Open Supervised Device Protocol) wiring runs. Its FEP insulation makes it appropriate for plenum or high-temperature routing environments. Installers working on card reader infrastructure, door controllers, and intercom systems will find this cable fits standard wiring practices for supervised device communication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRS485 and OSDP reader wiring application\u003c\/li\u003e\n\u003cli\u003e2-pair, 22 AWG stranded tinned copper conductors for flexibility and conductivity\u003c\/li\u003e\n\u003cli\u003eFEP insulation for high thermal resistance and low smoke emission\u003c\/li\u003e\n\u003cli\u003eStranded TC construction for repeated flex and routing through conduit\u003c\/li\u003e\n\u003cli\u003eDesigned for reliable signal integrity on serial data bus runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit cable for RS485 serial bus and OSDP reader wiring systems in commercial access control and building automation installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed low-voltage or electrical contractor in accordance with applicable NEC requirements for communication and signal cables. Power down all connected access control equipment and readers before making terminations. Maintain consistent polarity on RS485 differential pairs throughout the run to avoid signal errors. Do not route signal cable in the same conduit as high-voltage power conductors without appropriate separation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 22 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Type\u003c\/strong\u003e: Stranded Tinned Copper (TC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pairs\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: FEP (Fluorinated Ethylene Propylene)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: RS485, OSDP Reader\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BELDEN INC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6541FD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BELDEN","offers":[{"title":"Default Title","offer_id":51559419183410,"sku":"6541FD","price":2443.39,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/belden-inc-6541fd-rs485-osdp-reader-cable-2pr-22awg","provider":"Voomi Supply","version":"1.0","type":"link"}
