The Siemens 5TG2068 is a DELTA i-system flush-mounted BNC socket insert — a 2-fold female/female double jack for 75Ω coaxial signal distribution. It brings antenna, cable TV, and satellite IF connections into a standard 55×55mm wall frame, replacing loose cables snaking through a wall penetration with a clean, modular outlet. The 75Ω impedance is matched to video, antenna, and broadcast RF systems — not interchangeable with 50Ω BNC found on test equipment.

5TG2068 or 5TG2067 — which color?

The only difference between these two BNC double jacks is color. 5TG2068 is titan white (near RAL 9010, glossy) — the standard Siemens white for residential and commercial interiors. 5TG2067 is electric white (industrial matte) — designed for utility spaces where a non-reflective surface is preferred. Electrically and mechanically identical; choose by frame color.

50Ω or 75Ω — why impedance matters

BNC connectors come in two impedances, and they are not interchangeable. 75Ω BNC is the standard for video distribution, antenna systems, cable TV, and satellite IF — the entire broadcast and consumer RF ecosystem runs at 75Ω. 50Ω BNC is used in test equipment, RF instruments, and some data systems. Installing a 50Ω BNC socket in a 75Ω antenna distribution creates an impedance mismatch that causes signal reflections, ghosting on analog video, and bit errors on digital signals. The 5TG2068 is unambiguously 75Ω — correct for any TV/antenna/satellite wall outlet.

Which DELTA frames fit?

This is a standard 55×55mm modular insert. It fits all DELTA i-system, DELTA line, DELTA miro, DELTA profil, and DELTA style frames that accept 55×55mm center plates. A single module holder can accommodate up to two different functions — you can combine the BNC socket with another communication or power insert in the same frame.

Frequently Asked Questions

Is this socket suitable for CCTV cameras?

Yes — most analog CCTV cameras use 75Ω BNC for video. The 5TG2068 provides a clean wall outlet for camera signal distribution when the DVR is in a different room. For HD-over-coax systems (HD-TVI, HD-CVI, AHD), the 75Ω impedance path remains correct.

Does this socket include the BNC coupler barrel?

Yes — the socket is a complete double-jack insert. Both sides are BNC female, so you plug a male BNC cable into the front (room side) and another male BNC cable into the rear (wall side). No separate coupler needed.
