Product details

Fully insulated flag receptacle for 0.250" tabs

The 2-520128-2 is the red, 18-22 AWG member of TE's Ultra-Fast quick-disconnect receptacle line, accepting 0.250" (6.35mm) wide tabs at a 0.032" (0.81mm) thickness. The fully insulated housing and right-angle flag orientation suit inline wire-to-wire connections where the wire exits perpendicular to the tab axis. Tin-plated brass contact, crimp termination, free hanging mount.

Tab width and thickness match across series

The 0.250" tab width and 0.032" tab thickness of the 2-520128-2 match the Utilux non-insulated receptacle 1-1627194-4 (same width and thickness, 15-18 AWG) and the Utilux 1-1659250-0 (0.248" width, 0.031" thickness, 17-20 AWG). The Ultra-Fast insulation and flag orientation are the primary differentiators; the tab interface is shared across these active-production receptacles.
