It uses a 0.165" (4.20mm) pitch — the same spacing as the standard Mini-Fit Jr. line, but with a blind-mate geometry that lets you push two panels together without seeing the connector faces. This is the receptacle half; you need the separate crimp terminals and the matching plug to complete the wire-to-wire or wire-to-board connection.
The listing note says it plainly: contacts are not included. The 0015060101 accepts standard Mini-Fit female crimp terminals (Molex 44476 series for 20-24 AWG, or 45750 series for 16-20 AWG) that you terminate onto the wire and insert into the housing cavities. The mating plug is the male header half from the same Mini-Fit BMI series — look for the 42474-series header with matching circuit count and orientation. Panel-mounting is via the integral ramp locks on the housing sides; no additional hardware needed.
