The Molex 0511102851 is a 28-circuit, dual-row receptacle housing from the Milli-Grid 51110 series. It uses a 2.00 mm pitch and a 2.00 mm row spacing, giving you a compact 28-position footprint for wire-to-board harnesses where board space is tight.
Contacts Are Sold Separately — What You Need
The crimp termination lets you build the harness to length on site and re-pin a connector without swapping the whole assembly — a field-service-friendly setup. If you are replacing a damaged housing in an existing harness, you can pull the terminals out with a proper extraction tool and re-use them in this new shell, provided the contacts are still in spec.
Polarizing Key and Locking Ramp
That click is your confirmation the connector is locked, not just pushed home; a partially mated connector with a locking ramp can back out under cable strain, so seat it until you hear or feel the latch engage.
