The Siemens 6GT2815-0BN40 is a pre-assembled coaxial cable for the SIMATIC RF600 system, purpose-built to connect a UHF antenna to an RF600 reader. It comes terminated with R-TNC (female, straight) connectors on both ends, so it's a drop-in replacement for a 40 m run — no field termination needed.
Key ratings and what they mean for fit
Rated at 50 Ω characteristic impedance, which matches the standard for UHF RFID antenna systems — mismatched impedance would cause reflections and reduce read range. The maximum voltage rating of 2000 V is the cable's dielectric withstand, not an operating voltage; the actual RF signal is low-voltage, but this rating tells you the insulation can handle transient surges on long outdoor runs. Attenuation is specified at 0.13 dB/m at 900 MHz, so over the full 40 m length you lose about 5.2 dB. That's within the link budget of most UHF readers, but if you're pushing the edge of read range, factor that loss into your system gain calculation. The cable is halogen-free and carries a flame-resistant rating of CMR (UL/NEC) and FT4 (CSA) — that's riser-rated for plenum and vertical shaft installations where smoke toxicity matters. The designation LMR-400-FR LSZH UL confirms it's a low-smoke zero-halogen variant of the LMR-400 class, so it's suitable for indoor cable trays and enclosed spaces where code demands low-halogen cabling.
Where it's used
This cable is part of the SIMATIC RF600 UHF RFID system, used in logistics, warehousing, and production lines for identifying pallets, totes, and work-in-progress. The 40 m length is typical for connecting a reader cabinet to an antenna mounted on a gantry or dock door — long enough to route through cable trays but short enough to keep RF loss manageable.
