It uses a bayonet lock for quick mate and disconnect — the coupling nut engages with a quarter-turn, which is standard for BNC interfaces in test equipment, instrumentation, and RF distribution panels. The center contact is beryllium copper with gold plating, paired with a fluoropolymer dielectric, giving this jack the signal integrity for repeatable 50 Ohm transmission through the rated band.
The solder cup termination on the center contact and shield means you terminate the coax centre conductor and braid by hand with a soldering iron; no crimp tool required, which makes field replacement straightforward if you have a clean iron and steady hands.
Rated for 500 mating cycles, this jack holds up to regular reconnection in test setups or patch panels without the center contact wearing through the gold plating. The 500 V rating is the working voltage between center and outer conductor — adequate for most RF signal paths where the voltage swing is well below that ceiling.
If you are maintaining an existing design, verify the panel cutout and solder-cup termination match any proposed alternative before swapping the line item.
The lockwasher seats between the panel face and the nut to prevent the connector from rotating under cable strain or vibration — do not omit it during installation. The extended insulation feature (noted on the spec line) refers to the dielectric material extending past the mating face, which increases creepage distance between center and outer conductor at the interface.
