The Molex 0901560152 is a 12-circuit single-row receptacle housing from the C-Grid III 90156 series, designed for free-hanging (in-line) wire-to-board or wire-to-wire interconnects. The housing accepts crimp-terminated female socket contacts — the terminals are ordered separately, so the BOM needs a line for the matching contact part number.
What the Locking Ramp and Pitch Mean for the Build
The locking ramp is the primary mechanical retention feature — when the housing mates with a C-Grid III header, the ramp snaps over the header's latch and holds the pair engaged. In a harness that sees movement from equipment doors, robotic arms, or vehicle vibration, that ramp is what keeps the connection from walking loose.
Contacts and Termination — Crimp, Don't Solder
This housing accepts female socket contacts terminated by crimping — no soldering required. The contacts themselves are ordered separately; the housing ships empty. For the mating side, this receptacle mates with any C-Grid III single-row header (male pin) of the same pitch and position count.
