The 2-2366600-4: It's a free-hanging (in-line) connector body designed for crimp termination — you terminate the wires with the matching tab contacts, then insert them into the housing. The latch lock on each side gives a positive audible click when mated, holding the pair together in environments where vibration is a concern. The glass-filled thermoplastic shell handles -55°C to 125°C, so it's at home in an industrial cabinet or underhood in an automotive harness. This is the plug half; it mates with the corresponding Dynamic D-1000 receptacle header.
The One Thing You Need to Know Before Ordering
Contacts are not included with this housing. The listing explicitly notes that — you order the 2-2366600-4 shell, then buy the Dynamic D-1000 tab crimp terminals separately. For a 4-position plug you need 4 terminals. If you're filling a BOM line, make sure the terminal order code is on a separate line. The housing alone is just the plastic body and the latch locks.
Mating Half and Assembly
This plug housing mates with a Dynamic D-1000 receptacle header — the board-mount or panel-mount half with the same 4-circuit, 2-row layout. The latch lock on the plug sides snaps over the mating header's locking ramps. For the wire side, you crimp the tab contacts onto the wire (typically 18-22 AWG for this series, though confirm the wire range against the terminal datasheet), insert them into the housing cavities until the retention lance locks, then seat the plug onto the header. The black color is standard for the Dynamic D-1000 plug housings.
