The latch holder on the plug body locks onto the mating header's ramp, giving a positive retention that holds under vibration — useful in automotive, industrial control, and appliance harnesses where a loose connector means a service call.
The single-row layout means the harness wires exit in one plane, which simplifies routing in a confined junction box or along a frame rail. The 10-circuit count matches a 10-position BOM line exactly; if your circuit count is lower, you leave positions unused, but the latch still engages.
Termination and Mating: Crimp and Lock
The female socket contacts are crimp-terminated — you strip the wire, crimp the terminal, and insert it into the plug cavity until the latch clicks. The plug then mates with the corresponding Grace Inertia 2.0 header (male pin version, same pitch and position count). No secondary locking device is listed, so the primary latch is your retention. The free-hanging mount means this plug is not panel-mounted — it floats in the harness, which is standard for in-line connections.
