The Molex 2127242021 is the 2-circuit receptacle housing from the Micro-One 212724 series, designed for wire-to-board or wire-to-wire interconnects where a compact, reliable locking interface is needed in a 2.00mm pitch. This single-row housing accepts a female socket crimp terminal, and is intended for free-hanging (in-line) mounting.
The receptacle accepts a female socket contact (Molex Micro-One 212727 or 212728 series, depending on wire gauge), which is inserted into the cavity and locked by the integrated Terminal Position Lock (TPA) feature. The TPA is a secondary retainer that ensures the terminal is fully seated and resists back-out under vibration; it engages after the contact is inserted and must be closed before the housing is mated.
Glow wire and locking features
The housing is glow wire compliant. The bag packaging suggests hand-assembly or low-volume production runs.
