The two-row mating layout uses 2.77mm pitch, 2.84mm row spacing and a 1.385mm stagger. The housing drawing identifies two Ø3.15mm mounting holes, a 12.50mm flange height, 9.20mm male and 7.90mm female mating-height references, and a 17.50mm overall reference in the side views.
The male-terminal drawing shows an 18.00mm carrier-inclusive length reference, with 14.40mm and 8.04mm longitudinal details. The female-terminal drawing shows 17.24mm, 13.64mm and 7.29mm corresponding longitudinal references. Both include 7.60mm carrier pitch, Ø1.50mm carrier holes, Ø2.10mm forming references and 3.00mm strip details. Use the separate terminal sections to identify the correct contact form.
