The Molex 1510492201 is a 2-circuit receptacle housing from the CP-6.5 151049 series, designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications where a positive latch lock is needed to keep the pair mated under vibration.
2 circuits, 2 rows, 6.50 mm row spacing
Two positions in two rows means one contact per row. The 6.50 mm row spacing gives each terminal pocket enough physical separation to handle the current the CP-6.5 contact family is rated for — the housing itself does not limit the current; the crimp terminal and wire gauge do.
You need the matching Molex CP-6.5 female crimp terminal (order code 0450102001 or the equivalent from the 045010 series) and a suitable hand or pneumatic crimp tool. The terminal is a socket that inserts into the housing cavity and locks with a retention lance. The mating half is the CP-6.5 male header (e.g. 1510492101 for a 2-circuit version) or a male plug housing with the same latch geometry.
