A polarizing key prevents mismating with non-keyed counterparts. This is a workhorse connector for power distribution, sensor harnesses, and industrial control wiring where 5.00mm spacing provides good creepage for moderate-voltage circuits.
What the 5.00mm Pitch and 6 Positions Mean for Your Build
The 5.00mm pitch is a common power-grade spacing — wider than the 2.54mm signal pitch, giving room for larger-gauge wire and higher current per circuit without voltage breakdown between adjacent contacts. Six positions in a single row keeps the connector narrow along the board edge, useful for compact junction boxes or inline harness splices. The latch holder locks audibly on mate, and the polarizing key ensures the plug only seats one way — a field-friendly detail when wiring under a panel.
Termination is crimp, not solder, so you'll need the correct applicator tool or hand-crimp frame. The plug mates with a male header or pin header of the same 5.00mm pitch and 6-position count. The latch holder provides the retention force; no secondary lock or screw is required for most applications.
