Sta-Kon F4021 – Frequently Asked Questions
1) Can I use the F4021 ferrule on solid wire?
Ferrules like the F4021 are for stranded conductors. Solid 20 AWG already holds its shape under a screw clamp and does not need one, and crimping a ferrule onto solid wire gives you a poor mechanical bite. Use it on stranded 0.5 mm2 / 20 AWG control and signal wire.
2) Is the F4021 ferrule color coded, and what does white mean here?
It is white. That follows the older DIN color scheme this ferrule is built to, not the newer one, so if a panel is already populated with the current color code, white on a 0.5 mm2 ferrule may not match what your techs expect. Match by the stamped size, not the color, when mixing generations.
3) What is the barrel made of on the Sta-Kon F4021, and what is the insulation?
Copper barrel with a polypropylene insulating collar. The copper crimps down on the strands for the electrical connection; the PP sleeve is there for strain relief at the wire entry and to keep stray strands from bridging to the neighboring terminal.
4) Do I need a special crimp tool for the F4021 ferrule?
Yes, an insulated ferrule crimper. Ferrules are crimped with a square or trapezoidal die sized to the conductor, not with the oval die used on insulated ring and spade terminals. Set the tool to the 0.5 mm2 / 20 AWG position for this part.
5) What is the exact part number to order for a 0.5 mm2 insulated ferrule from Sta-Kon?
F4021 is the manufacturer part number, described as an insulated PP old DIN ferrule, No. 20 / 0.5 mm2. Order by that number if you are standardizing a panel build so every reel of 20 AWG control wire gets the same termination.
6) Where is the Sta-Kon F4021 ferrule made?
Germany. That matters if your job spec or procurement file requires country of origin documentation on electrical terminations.
