Product details

The 221185-1: The 75 Ohm impedance targets video, broadcast, and data-communication signal paths where 50 Ohm would be a mismatch.

This plug is specified for the Belden 9248 cable group, which includes common 75 Ohm video coax types like RG59.

Electrical and Mechanical Ratings

The gold-plated brass center contact handles the signal path; the polyethylene dielectric maintains the 75 Ohm characteristic through the connector body.

Frequently asked questions

What is the impedance of 221185-1?

75 Ohms — this is the characteristic impedance of the connector, matched to 75 Ohm cable and system impedance.

What is the insertion loss of 221185-1?

0.15 dB, measured at the rated frequency range.

How many mating cycles does 221185-1 support?

500 cycles — the gold-plated center contact and bayonet lock are designed for repeated field connects.

Is 221185-1 a male or female connector?

Male pin — the center contact is a pin, and the body is a plug that mates with a BNC jack or receptacle.
