0.110" tab width, 18-22 AWG range
The 521437-2 is the white-insulated member of TE's Ultrapod quick-disconnect receptacle line, accepting 0.110" (2.79mm) male tabs on 18-22 AWG wire. The tin-plated brass contact and fully insulated housing suit general-purpose power and signal disconnects where repeated mate/unmate cycles are moderate.
White vs natural vs black — same tab width
Within the Ultrapod 0.110" series the 521437-2 (white) shares its tab width, wire range, and overall length with the natural 521436-2 and the black 521408-2 — the colour distinguishes the assembly position or circuit function on the harness.
