Overview
The 3-520132-2 is the 14-16 AWG female receptacle in TE's Ultra-Fast fully insulated quick disconnect series. It accepts a 0.250" (6.35mm) tab, 0.032" (0.81mm) thick, and accommodates an insulation diameter up to 0.185" (4.70mm).
How it compares
The 3-520132-2 accepts 14-16 AWG wire and a 0.185" (4.70mm) insulation diameter, while the 280050-2 (Faston series, non-insulated) accepts 15.5-20 AWG and a smaller 0.091" to 0.130" (2.31mm to 3.30mm) insulation diameter — select the 3-520132-2 when the circuit requires 14-16 AWG and fully insulated termination.
