Sta-Kon RBD1887F FLLY INS NYL 90DEG FEM DSC, 16-14

The RBD1887F takes 16-14 AWG wire. That's the blue color code, and the blue nylon insulation on the barrel is how you'll pick it out of a bin without reading the stamp. Run a 12 AWG conductor into it and the crimp won't hold; step up to the yellow 12-10 AWG body instead.

A flag terminal puts the tab receptacle at a right angle to the wire, so the conductor leaves the terminal sideways rather than straight off the back. That's what you want in a tight control box, a motor junction, or behind a switch where there isn't depth to bend a straight disconnect without stressing the crimp. If you've got room to run the wire in line with the tab, a straight female disconnect is the simpler part. The RBD1887F is the 90 degree version in 16-14 AWG.

It carries UL file E66716 and is rated 600 V. That covers the usual 120/208/240/277/480 V control and branch circuit work an electrical contractor or MRO shop runs into, and the UL file number is what a plan reviewer or inspector will want cited on a submittal.

Fully insulated. The nylon sleeve covers the barrel and carries back over the wire entry, so there's no bare brass at the crimp once it's made. That matters in a crowded enclosure where terminals sit shoulder to shoulder and in anything a maintenance tech opens live. A partially insulated disconnect leaves the barrel exposed behind the sleeve.

The RBD1887F is nylon/polyamide. Nylon takes more abrasion and holds up better to heat and to oils and solvents than a vinyl sleeve, which is why it gets specified for motor connections, appliance work, and anything in a hot or dirty enclosure. Vinyl is the cheaper sleeve and it's fine for clean, cool, low-abuse control wiring. Both crimp the same way with the same die.

Country of origin is the United States. For a government, school district, or healthcare procurement officer working a Buy American or domestic preference spec, that's the line item that has to survive review, and it's the reason this part gets pulled into federal and institutional MRO stock in the first place.

The manufacturer part number is RBD1887F. When you quote a flag disconnect you need three things nailed down: the wire range (16-14 AWG here), the tab size it plugs onto, and the angle (90 degree flag rather than straight). Ordering by AWG color alone is how the wrong tab width shows up on site, so put the full RBD1887F number on the PO.

Brass. Brass barrels take a crimp well and hold it, and they're the standard choice for a disconnect that will be pulled on and off a tab through the life of the equipment. The mating surface is what does the work on a quick disconnect, not the crimp alone, so the barrel material is worth confirming when you're standardizing a panel build.
