It presents a BNC jack (female socket) on one end and an N plug (male pin) on the other, making it the go-to part when you need to connect an N-cabled device to a BNC bulkhead or vice versa without cutting and re-terminating. The adapter is built around a 50 Ohm impedance path — the standard for most telecom, test equipment, and RF distribution systems — so it won't introduce a mismatch in a 50-ohm line. The BNC end uses a bayonet lock — quarter-turn mate, quick to connect and disconnect in test setups or field patching. The N end uses a threaded coupling, which gives a more vibration-resistant, weather-tight connection once torqued. That dual-fastening combo is the whole point of this adapter: you get the convenience of a BNC bayonet on one side and the mechanical security of an N thread on the other. The adapter is straight, not right-angle, so it keeps the cable axis aligned with the connector axis — useful when routing through tight enclosures or panel cutouts where a right-angle adapter would add a bend radius constraint. The 222321-1 carries an Obsolete product status from TE Connectivity. That means the manufacturer no longer produces it, and there is no official factory stock or last-time-buy window remaining. There is no listed official replacement from TE, so if you need a drop-in BNC-to-N adapter with the same gender and impedance, you will need to evaluate an alternative part number from TE or another manufacturer against your mechanical and electrical requirements. The adapter is packaged in bulk — no individual retail packaging, just loose units in a bag or box. That is typical for this class of component; it keeps the per-unit cost down when buying for a bench stock or production run.","metaTitle":"TE Connectivity 222321-1 BNC to N Adapter, 50 Ohm, Obsolete","metaDescription":"TE Connectivity 222321-1 BNC jack to N plug adapter, 50 Ohm, straight, free-hanging.
