Product details

The 112806-75: At 75 Ohm it's the standard for composite video, SDI, and CCTV — not the 50 Ohm RF you'd find on a spectrum analyzer.

Fit and Mounting — Board Edge, End Launch, or Bulkhead

This jack mounts either at the board edge with an end-launch footprint or through a panel with the front-side nut — the kit includes the connector, a lockwasher, and the nut, so you're not hunting for hardware. The shield termination is solder, same as the centre contact, so you'll need an iron on site. The bayonet lock is quick to mate and unmate, and the 75 Ohm impedance is baked into the PTFE dielectric — no tuning, no guesswork.

What's the Difference Between 112806-75 and 112806-50?

The 112806-75 is the 75 Ohm variant; the 112806-50 is its 50 Ohm sibling. Same BNC interface, same gold body, same bayonet lock — the impedance is the only spec that changes.

Frequently asked questions

What is the impedance of 112806-75?

That's the impedance for video, broadcast, and CCTV — not the 50 Ohm used for RF test equipment.

Does 112806-75 come with mounting hardware?

Yes, the package includes the connector, a lockwasher, and a nut — three pieces total. No separate hardware order needed for a bulkhead install.
