Product details

The 031-70566-12G: The 75 Ohm impedance and 12 GHz frequency rating make it a natural fit for video distribution, CCTV, broadband data, and test equipment where the 75 Ohm standard is required rather than the 50 Ohm common in RF/microwave.

Cable-Specific Crimp — Belden 4855R

This connector is specified for Belden 4855R cable. The included ferrule and crimp contact are sized for that cable group, so the shield termination (crimp) and centre conductor termination (crimp) are a matched set. Using a different cable type will change the impedance match and the mechanical grip — stick with the listed cable or verify the crimp dimensions against your cable's OD and dielectric diameter.

500 Mating Cycles with Bayonet Lock

The bulkhead mount with front-side nut and included gasket provides a weather-resistant panel seal when torqued correctly.
