Sta-Kon RA4F – Frequently Asked Questions
1) What stud or screw size does the RA4F fork terminal fit?
It's sized for an M4 stud or screw. The fork (spade) tongue slides in around a partially loosened M4 terminal screw, so you don't have to pull the screw all the way out to land the wire, which is why these get used on terminal strips and control panel blocks.
2) Is the red insulation on this terminal a color code for wire size?
Yes. The RA4F is red, and in the standard insulated-terminal color code red covers the 0.5 to 1.5 mm2 (22-16 AWG) range. Blue is the next band up and yellow above that, so on a panel you can tell at a glance which gauge was landed.
3) Fork terminal or ring terminal for a control panel terminal block?
A fork terminal like the RA4F is the faster install: back the M4 screw off a couple of turns and slide the tongue in sideways. A ring terminal has to go over the screw, meaning full removal of the screw and washer. The tradeoff is retention. A ring can't pull off a loose screw, a fork can, so vibration-prone or safety-critical connections are usually specified as rings. For panel wiring and re-terminations that get touched often, the fork wins on labor.
4) What is the Sta-Kon RA4F terminal made of?
The conductive barrel and tongue are electrolytic copper, with a polycarbonate insulating sleeve over the crimp barrel. Copper keeps the resistance low across the joint, and the polycarbonate sleeve takes more heat and impact than a soft vinyl sleeve, which matters if the terminal is near a heat-producing device inside an enclosure.
5) Do I need a special crimp tool for the RA4F insulated fork terminal?
Use an insulated-terminal crimp tool matched to the red 0.5-1.5 mm2 color band. Those dies compress the barrel through the polycarbonate sleeve without splitting it. A bare-terminal or uninsulated die will crush or crack the insulation, and pliers will not give you a gas-tight crimp.
6) Where is the Sta-Kon RA4F terminal manufactured?
Country of origin is Sweden. That's the detail institutional and government procurement buyers usually need for origin documentation on a bid package.
7) What is the manufacturer part number for this red M4 fork terminal?
The part number is RA4F from Sta-Kon. Read it as the red insulated size band, M4 stud, F for fork tongue, so adjacent parts in the series change either the stud size or the tongue style.
