WBT-0681 Ag Spade Connector

Same as the WBT-0661Ag sandwich spade connector, but with a larger fork size of 5/16 inch / 8.1mm .

Pure Fine Silver contact is direct Platinum plated to protect contact metal from tarnish.

Easily accepts wire sizes up to 10mm² / 8AWG Solid Core, aka 10AWG Stranded.

From US Patent #6,319,078
High-current spade lug with elastomer shock absorber for pro-gressive contact pressure eliminating structure-borne and air-borne noise as well as magnetostriction.
With insulation body for safety conformable use as loudspeaker cord plug admissable in line with CE3 EN 60065 and the international standard IEC4 65 (>34.5 volts).

1. Mechanics
      • one-piece construction, contact elements with narrow tolerance
     • dual screwing cage (contact, strain relief)
     • VA-elastomer shock absorber (hydraulic principle)

2. Materials
      • signal conductor: fine silver
     • absorber cap: high-grade steel VA, non-ferromagnetic
     • elastomer damper: NBR (nitrile-butadiene-rubber)
     • insulation material: Makrolon1 (polycarbonate), T. max. 85-110°C

CE3 conformable inline with EN 60065 and IEC4 65
     • marking ring: TPU (thermoplastic polyurethane), T. max. 50-95°C

3. Surface
     • signal conductor: nickel-free platinum finish, non-ferromagnetic

4. Operating characteristics
     • constant current ID = 102 A
     • authorized max. peak current IS = 103 A
     • contact resistance Rü < 10-4 Ohm
     • insulation resistance Riso> 1014 Ohm
     • electric strength of the insulation > 30 kV

5. Connection options
     • designed for solder-free crimped connections
     • internal terminal for crimped cable ends up to 10 mm2 (7 AWG), permanent fixing by self-securing headless screws
     • external terminal with 6 or 8 mm contact fork (0661 & 0681 respectively) 

6. Warning against usage of contact cleaners:
     Their contents may cause damage to the insulators!
