What it is and where it fits
The Siemens 6GT2815-0BH30 is a pre-assembled coaxial cable in the SIMATIC RF600 family, purpose-built for connecting a UHF antenna to an RF600 reader. It comes terminated with R-TNC (female, straight) connectors on both ends, so it is a drop-in link between the reader port and the antenna — no field termination needed. The cable is 3 m long, has a characteristic impedance of 50 Ω, and is rated for a maximum voltage of 1000 V. The sheath is black, the dielectric is PE, and the cable designation is LMR-195. This is a sealed assembly rated IP65, so it handles washdown environments and outdoor exposure on the antenna side of an RFID portal. The braided shield is tin-plated copper, giving good EMI rejection over the 3 m run. At 900 MHz the attenuation is 0.365 dB/m, meaning about 1.1 dB total loss across the full length — acceptable for most UHF read ranges.
Key ratings and what they mean for fit
The 1000 V maximum rating is the dielectric withstand of the cable itself, not the operating voltage of the RFID system (which is usually well under 50 V). It means the cable can coexist in a tray with higher-voltage power cables without breakdown risk, as long as the jacket is intact. Fire behavior is flame-resistant per UL/NEC and CSA CMR / FT4 (applies to the cable only, not the plug). That qualifies it for plenum and riser runs in commercial buildings — a common requirement when the cable passes through air-handling spaces. Minimum bend radius is 12.7 mm for a single bend and 50.8 mm for repeated flexing. That is tight enough to route through standard cable trays and around reader enclosures, but repeated sharp kinks will degrade the impedance match. Radiological resistance to UV radiation is listed as resistant, so the sheath holds up in direct sunlight — important for outdoor antenna mounts.
