Product details

Fully insulated quick disconnect

The 2-520263-4 is a fully insulated female quick disconnect receptacle from the TE Ultra-Fast series, accepting 18-22 AWG wire with a 0.250" (6.35mm) tab width. The tin-plated phosphor bronze contact and crimp termination suit repeated mating cycles in free-hanging in-line installations.

Tab width and wire range

The 0.250" (6.35mm) tab width and 0.032" (0.81mm) tab thickness are shared with the Utilux 1627194 (non-insulated, 15-18 AWG), while the 1-1659250-0 Utilux runs a 0.248" (6.30mm) tab and narrower 17-20 AWG range — the 2-520263-4's fully insulated barrel handles larger insulation diameters up to 0.230" (5.84mm).
