Sta-Kon RZ4 – Frequently Asked Questions
1) What wire gauge range does the Sta-Kon RZ4 ring terminal accept?
The RZ4 is sized for 0.25 to 0.75 mm2 conductor, which is roughly 24 to 18 AWG. If your conductor is 16 AWG or larger it will not seat in this barrel, and the green insulation is the color code for that small range, so a green barrel on the panel tells you it is a 0.25-0.75 mm2 crimp.
2) Will the RZ4 ring terminal fit an M4 stud or screw?
Yes, the RZ4 ring is an M4 size tongue, so it drops over an M4 stud or screw, which is the common 8-32 / #8 equivalent on terminal blocks and ground studs. For a larger stud you need a different ring size, not this one.
3) Is the Sta-Kon RZ4 a solid metal lug or an insulated crimp terminal?
It is an insulated crimp terminal. The conductor barrel is electrolytic copper and the sleeve over it is polycarbonate, which holds its shape better than a vinyl sleeve when you are crimping into a tight panel. You crimp it on with a terminal tool, no soldering.
4) Why would I pick a polycarbonate insulated ring terminal over a nylon or vinyl one?
Polycarbonate sleeves are rigid and hold up to handling and heat better than soft vinyl, so they are the choice for control panels and machine wiring where the terminal gets pulled and re-landed. Vinyl insulated rings are the cheaper, more flexible option for general low-stress work. Either way, the ring tongue is the right pick over a fork or spade when the connection must not pull off the stud if the screw loosens.
5) Is the terminal barrel copper or aluminum?
Electrolytic copper. That means it is for copper conductor only, not aluminum, and it gives you the low resistance you want on signal and control circuits in the 0.25-0.75 mm2 range.
6) What part number do I order for the Sta-Kon green M4 ring terminal, and where is it made?
Order it as Sta-Kon RZ4. That is the full manufacturer part number for the green polycarbonate insulated M4 ring terminal, and it is manufactured in Sweden.
