Sta-Kon RA5RR – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RA5RR ring terminal accept?
The RA5RR takes 0.5 to 1.5 mm2 conductor, which is the 22 to 16 AWG range in US sizing. Red insulation is the standard color code for that band, and the terminal's barrel is sized for it, so stranded control or signal wire in that range crimps correctly. Anything heavier than 1.5 mm2 will not seat in the barrel and needs the next size up.
2) Is the insulation on the Sta-Kon RA5RR nylon or vinyl?
Neither. The insulating sleeve is polycarbonate, which holds its shape at higher temperature than PVC and resists cracking better than vinyl when the barrel is crimped. That matters on control panels and machine wiring where terminals sit near heat sources.
3) Should I use a ring terminal or a fork terminal on my terminal strip?
Use the ring, like the RA5RR, anywhere vibration or a safety circuit is involved: the closed barrel cannot slide off a loosened screw, so the connection stays captive. A fork or spade is only worth choosing when the screw is hard to remove and you need to drop the wire in from the side. For panel grounds and anything on a moving machine, the M5 ring is the right call.
4) Do I need a special crimper for the RA5RR, and is it insulated?
It is a pre-insulated terminal, so it crimps with an insulated-terminal tool (the color-coded red die for 22 to 16 AWG), not with a bare-terminal nest. The polycarbonate sleeve covers the barrel, so no additional heat shrink or boot is needed to insulate the joint once crimped.
5) How do I identify the RA5RR when ordering replacements for an existing panel?
Order by brand and part number: Sta-Kon RA5RR. The R prefix color red and the 5 for the M5 stud are the two things to match if you are pulling one off a panel to compare. Country of origin is Sweden.
