4-Position Single-Row Plug for Wire Harness Builds
The Molex 5046940404 is a 4-circuit plug from the CP-3.3 504694 series, designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications where a compact single-row interface is needed. The 0.130" (3.30 mm) pitch gives enough space between contacts for reliable crimp termination without crowding the wire entry, making it a practical fit for control cabinets, appliance internals, and low-voltage power distribution inside equipment.
The latch lock fastening provides audible positive retention once the plug is mated with the corresponding CP-3.3 receptacle housing.
The 0.130" (3.30 mm) pitch is wider than the common 2.54 mm (0.100") header spacing, which means the four positions occupy about 13.2 mm of board edge or harness real estate. That extra pitch gives more creepage for the operating voltage range typical of this series and makes hand-termination of wires easier than on a finer-pitch connector.
PBT holds up well in moderate industrial environments — it resists many common solvents and maintains dimensional stability under the latch load during repeated mate cycles. The single-row, 4-position layout keeps the connector compact for tight wire-routing paths inside equipment enclosures.
