7-Position Circular Plug with Threaded Coupling
The JAE SRCN6A16-7P is a 7-position circular plug with male pins, part of the SRCN series of threaded circular connectors. It uses a free-hanging (in-line) mounting style with a threaded coupling nut for secure mating — the same fastening found on MIL-DTL-5015 style connectors. Typical applications include communication systems, telecommunications, and test equipment where a rugged, field-serviceable circular interconnect is needed.
Silver Contacts, 10 A per Circuit, Dual Voltage Rating
Each copper alloy contact is rated 10 A and plated with silver on the mating surface — silver is the standard choice for power circular connectors because it handles higher current without the contact resistance rise that tin shows over time. The voltage rating is 250 VAC or 350 VDC, so the AC and DC limits differ: the DC ceiling is higher because there is no zero-crossing arc extinction.
Integrated Backshell and Cable Clamp for Strain Relief
The plug ships with a backshell and cable clamp built in — the cable opening is 0.453" (11.51 mm), which accepts a range of cable diameters up to roughly 11.5 mm. The backshell and clamp provide strain relief at the cable exit, preventing the solder cup terminations from bearing the cable weight. Termination is solder cup, so you hand-solder each wire into the cup — no crimp tool needed, but each joint must be inspected for wicking and cold solder.
Same Shell Size, Different Position Count: SRCN6A16-10P
The SRCN6A16-10P shares the same shell size 16-7 insert pattern and the same 0.453" cable opening, but carries 10 positions instead of 7.
