What it is and where it fits
The Siemens 6GT2815-0BN10 is a pre-assembled coaxial cable from the SIMATIC RF600 family, designed as a plug-in connection between an RF600 reader and a UHF antenna. It carries a characteristic impedance of 50 Ω, which is the standard for UHF RFID antenna feeds — mismatching this value introduces return loss and reduces read range. The cable is terminated with R-TNC (female, straight) connectors on both ends, so it drops directly into the reader and antenna ports without field termination. The assembly is rated IP65, meaning the connector bodies and cable jacket withstand dust ingress and low-pressure water jets — suitable for washdown areas on a production floor or outdoor installations where the reader cabinet is exposed to weather.
Key ratings and what they mean for fit
Maximum voltage rating is 1000 V, which is the insulation rating of the cable and connectors. Attenuation is specified at 0.365 dB/m at 900 MHz, which is the center of the UHF RFID band (860–960 MHz). Over the 10 m length, that works out to roughly 3.65 dB of loss — about half the power is dissipated in the cable. For a typical reader output of 30 dBm, the antenna sees about 26.35 dBm. If your installation requires a longer cable run, factor this loss into the link budget; the reader's output power may need adjustment to stay within regulatory limits. The cable is designated LMR-195, a low-loss 50 Ω coaxial cable with a solid copper inner conductor and a braided shield of tin-plated copper wires. The minimum bend radius with a single bend is 12.7 mm; with repeated flexing, keep bends above 50.8 mm to avoid work-hardening the braid. Flame rating is CMR (Communications Riser) per UL/NEC and FT4 per CSA, but only for the cable without the plug — the assembled connectors may have a different listing. For plenum-rated installations, verify the connector's own flame rating separately.
