The three-row arrangement gives you a compact square footprint for a 9-circuit power interconnect, keeping the connector face smaller than a single-row 9-position housing would be. Each position accepts a female socket crimp terminal (sold separately — see the FAQ for compatible terminal part numbers), terminated to the wire before insertion into the housing. The 3.96 mm pitch provides enough spacing between contacts for the 600 V rated creepage typical of the Power Double Lock series, without forcing oversized wire routing. ## Mating and Termination — What Connects Here No tools are needed for mating or unmating — the latch releases by pressing the ramp, making it field-serviceable.","metaTitle":"TE 177903-1 Power Double Lock Plug Housing, 9 Pos, 3.96mm","metaDescription":"TE Connectivity 177903-1 Power Double Lock plug housing, 9 positions, 3 rows, 3.96mm pitch.
