The 1274544-1: The 1.0/2.3 series is a compact coaxial connector family common in telecom and test equipment where a push-pull coupling saves panel space over a threaded SMA.
RF Performance and Mechanical Endurance
The 50 Ohm impedance and 10 GHz frequency ceiling are the headline specs here — at 10 GHz the interface is near its practical limit; above that the VSWR climbs and the signal degrades. The 500 mating cycles are solid for a push-pull connector: the gold-over-phosphor-bronze centre contact and gold-plated brass body resist corrosion and wear through repeated field-service reconnections.
Obsolete — Sourcing and Cross-Reference Reality
No TE Connectivity successor part number has been published for this exact 1.0/2.3 right-angle jack. For a BOM that needs this specific interface and mounting, the only sourcing path is surplus or broker inventory.
Panel mount with a front-side bulkhead nut — the lockwasher prevents the nut backing off under vibration. The package includes the connector, lockwasher, and nut as three pieces.
