Product details

Quick-connect receptacle for 18-22 AWG

The 2-520405-2 is the 18-22 AWG member of TE's Ultra-Fast Plus fully insulated quick-connect receptacle line, terminated by crimp and installed free-hanging. It accepts a 0.250" (6.35mm) tab width and 0.032" (0.81mm) tab thickness, with a tin-plated brass contact and an insulation diameter range of 0.060" to 0.135" (1.52mm to 3.43mm).

Tab width and wire gauge contrast with Utilux peers

The 2-520405-2 uses a 0.250" tab width and accepts 18-22 AWG, while the Utilux 1-1659250-0 uses a 0.248" (6.30mm) tab width and accepts 17-20 AWG, and the Utilux 1-1627194-4 uses a 0.250" tab width and accepts 15-18 AWG — the wire gauge range and tab width differ, so match the wire size to the terminal's rated range.
