Bulk Supply of DIN Standard Tin Plated Copper Terminal Ferrules with Dual Insulation

Pricing breaks down nicely depending where you are—sample quantities are roughly $0.03 a piece, mid-range orders around $0.018, and bulk shipments under a penny per unit (usually 50,000+). It's what it does: gets you solid termination performance without eating into margins on every panel you build.

The dual sleeve on these is PA66 for teh color-coded sleeve, then PVC over that for extra heat and abrasion resistnce—we routinely see them hold up fine form -40°C all the way to +105°C. That cold forming process leaves the copper bellmouth end pretty clean, so wires slide in easier than some die-stamped alternatives.

You're looking at tinned 99.9% copper, so conductivity is better than the basic alloy stuff for corrosive environments, and the tin layer isn't just for show—it really cuts oxidation in humid cabinets. Wire range spans 0.5mm² to 16mm², which covers pretty much anything in control panels or distribution blocks.

100pcs per bag is standerd, but our company can do custom packaing if your line prefers 500-piece strips or whatever works—just give a heads-up on MOQ for that. UL listing is current, though I'd double-check local version if you're selling into Canada, as they sometimes want their own marking.

One thing most buyers don't realize is these aren't meant for silicone-insulated wires above 105°C rated cable—the PVC starts softening near upper limit. Anyway, for standard PVC wiring up to 16mm², they're basically a drop-in fit.
