The blind-mate feature and integrated board guides simplify alignment in panel or backplane installations where you cannot see the connector pair during engagement. The 3.00 mm pitch and 0.118\" row spacing set the drill pattern for the PCB — a 2 x 2 grid with 3.00 mm between adjacent holes in each row and between rows. The UL94 V-0 LCP housing holds up in enclosed equipment where flame rating is required. The board guides on the housing take the alignment load during blind mating, protecting the signal pins from shear damage.","metaTitle":"Molex Micro-Fit 3.0 BMI 0447640403, 4-pos Receptacle, 3.00mm","metaDescription":"Molex 0447640403 Micro-Fit 3.0 BMI receptacle, 4 circuits, 3.00mm pitch, 5A, gold plating.
