12-Position Receptacle Housing, 5.00 mm Pitch, Three Rows
At 5.00 mm pitch, each contact cavity has room for a 20-14 AWG wire with a decent crimp barrel and a secondary lock (the Junior Power Timer terminal family supports that range). The 0.217" (5.51 mm) row spacing gives you enough dielectric separation between rows for the 600 V rating the series carries — no tracking worries in a damp engine bay. Three rows means the 12 positions fit in a connector body that is wider than a two-row 12-position but shorter in length, which can help when routing a harness bundle around a tight corner. The blue colour is a visual cue on the line — you spot the wrong housing before it gets crimped.
The crimp termination gives a gas-tight connection when you use the correct TE hand tool or applicator; the terminal locks into the cavity with a positive tang, and the housing's primary latch holds the connector mated to the header. No secondary TPA (terminal position assurance) is listed for this housing, so seat each terminal fully until you hear the tang click — pull-back after crimp is the most common field defect on this series.
