Faston female terminal for 0.187" tabs
The 100494-2 is the non-insulated female member of TE's Faston quick-disconnect terminal line, designed for 0.187" (4.75mm) male tabs and 15-20 AWG wire. Tin-plated brass construction, crimp termination, and a free-hanging in-line mount suit it for field-terminated harness work where insulation is not required over the connection.
Same-series siblings at different tab widths
Within the Faston family the 100494-2's 0.187" tab width sits between the 0.250" (6.35mm) 1627194 and the 0.312" (7.92mm) 1377175 — all share tin-plated brass, crimp termination, and free-hanging mount, so the tab width is the selection axis for matching the male blade.
