Distance between connector pin centrelines. For dual row products pitch defines distance between both pins and rows. Note 0.8 x 1.2mm (0.31” x .047”) is the exception to this rule.
Defines the orientation which a connector sits on the PCB. Vertical (straight) is 90° to the PCB, right angle (horizontal) is 180° to the PCB. Use the appropriate mating connector pairs for parallel, co-planar and right angle PCB mating configuration.
