10-Position Circular Plug for Instrument-Grade Power and Signal
The JAE SRCN6A21-10P is a 10-position circular plug from the SRCN series, configured with male pins and a solder cup termination. The threaded coupling nut provides vibration-resistant mating, and the included backshell with cable clamp handles strain relief for the cable entry, which accepts jackets up to 0.551" (14.00 mm) OD. The shell is machined from aluminum alloy with a nickel finish — standard for equipment that needs RF shielding and corrosion resistance in indoor environments. Silver plating on the mating contacts gives low contact resistance for power duty, though the cycle life is below what gold-plated signal contacts would deliver. Typical applications include communication systems, telecommunications infrastructure, and test and measurement equipment — anywhere a field-terminable, threaded circular connector is needed for power or mixed-signal wiring up to 10 A per circuit.
Wiring and Field Termination — Solder Cup Assembly
Termination is solder cup, not crimp — each of the 10 male pins has a cup that accepts tinned stranded wire. No crimp tool or die set is required, which makes this connector practical for prototype builds, repair, and low-volume harness assembly where a crimp press isn't justified. The trade-off is assembly time: each wire is soldered individually, and the joint quality depends on the operator's technique. The backshell and cable clamp (included with the connector) secure the cable jacket after termination. The 0.551" (14.00 mm) cable opening sets the maximum cable OD that fits through the backshell — a cable with a jacket larger than that won't seat fully. The coupling nut threads onto the mating receptacle, and the O-ring seal at the interface (standard for this connector class) keeps moisture and dust out when mated.
Mating Half and Position Count Check
The mating receptacle for this plug is the SRCN6A21-10S — same shell size 21-10, same 10 positions, but configured with female sockets. Both parts share the 10 A current rating, silver contact finish, and threaded coupling.
