Product details

The 034-1021: It mates with a 75 Ohm BNC HD plug using the bayonet lock — the same twist-and-lock feel as a standard BNC, but in a smaller shell. Rated operating temperature is -65°C to 165°C.

CCTV and Video Signal Path — Why 75 Ohm Matters

The 034-1021's 4.5 GHz bandwidth covers the full HD-SDI data rate (1.485 Gbps) and 3G-SDI (2.97 Gbps) with margin. If you are wiring a CCTV head-end or a broadcast rack, this connector keeps the return loss low through the patch panel. The shield termination is solder, so you get a solid 360° bond to the cable braid — no crimp-on ferrule to corrode or loosen over time.

Frequently asked questions

What is the impedance of the 034-1021?

The 034-1021 is a 75 Ohm BNC HD receptacle. This impedance is standard for video and CCTV coax systems — it matches RG59 and similar 75 Ohm cables.

Can the 034-1021 be used for CCTV systems?

Yes. The 75 Ohm impedance and 4.5 GHz bandwidth make it suitable for analog CCTV, HD-SDI, and 3G-SDI video signals. The bayonet lock and 500 mating cycles suit patch-panel or head-end use where cables are reconnected frequently.
