详情描述
•LMR®standard is a UV Resistant Polyethylene jacketed cable designed for 20-year service outdoor use.The
bending and handling characteristics are significantly better than air-dielectric and corrugated hard-line cables.
•LMR®-DB is identical to standard LMR plus has the advantage of being watertight.The addition of waterproofing compound in and around the foil/braid insures continuous reliable service should the jacket be
inadvertently damaged during installation or in the future.
•LMR®-FR is a non-halogen(non-toxic),low smoke,fire retardant cable designed for in-building runs that can be routed anywhere except air handling plenums.LMRFR has a UL/NEC&CSA rating of‘CMR’and‘FT4’
respectively.
•LMR®-FR-PVC is a general-purpose indoor cable and has a UL/NEC&CSA rating of‘CMR’and‘FT4’respectively.It is less expensive than LMR-FR,however it emits toxic fumes(HCL)and greater smoke density
when burned.
•LMR®-PVC is designed for low loss general-purpose indoor/outdoor applications and is somewhat more flexible than the standard polyethylene jacketed LMR.
•LMR®-PVC-W is a white-jacketed version of LMRPVC for marine and other indoor/outdoor applications where color compatibility is desired.
•Flexibility and bendability are hallmarks of the LMR-400 cable design.The flexible outer conductor enables the tightest bend radius available for any cable of similar size and performance.
•Low Loss is another hallmark feature of LMR-400.Size for size LMR has the lowest loss of any flexible cable and comparable loss to semirigid hard-line cables.
•RF Shielding is 50 dB greater than typical single shielded coax(40 dB).The multi-ply bonded foil outer
conductor is rated conservatively at>90 dB(i.e.>180 dB between two adjacent cables).
•Weatherability:LMR-400 cables designed for outdoor exposure incorporate the best materials for UV resistance and have life expectancy in excess of 20 years.
•Connectors:A wide variety of connectors are available for LMR-400 cable,including all common interface types,reverse polarity,and a choice of solder or non-solder center pins.Most LMR connectors employ crimp outer attachment using standard hex crimp sizes.
•Cable Assemblies:All LMR-400 cable types are available as pre-terminated cable assemblies.Refer to the section on FlexTech for further details.
