Description
QMA Jack (Female) Right-Angle Bulkhead Connector | Thru-Hole PCB | Quick-Lock | DC–6 GHz
The ROSNOL QMA Jack (Female) Right-Angle Bulkhead Mount Connector, model QMA2IA59-2610A/91, is designed for compact RF and microwave assemblies requiring reliable PCB integration from DC to 6 GHz. Featuring a controlled 50-ohm impedance, this connector delivers stable electrical performance with a typical VSWR of ≤ 1.30 and controlled insertion loss specified at ≤ 0.05 × √F (GHz) dB. RF leakage performance is optimized across the operating band, supporting consistent signal integrity in high-density PCB layouts.
This connector adopts a quick-lock coupling mechanism, enabling fast mating and demating while maintaining secure interface retention. The right-angle bulkhead configuration with through-hole PCB mounting supports robust mechanical stability, while the soldered center contact ensures dependable electrical continuity. Mechanical performance includes defined engagement and disengagement forces and a minimum interface retention force to support repeated installation cycles.
The QMA2IA59-2610A/91 is manufactured with a gold-plated brass body and a gold-plated beryllium copper center contact over non-magnetic nickel-phosphorus underplating. PTFE insulation maintains dielectric stability across the specified temperature range. The connector is produced in ISO 9001-certified facilities and is fully compliant with RoHS and REACH requirements.
