Miniature rectangular multicontact connectors MB series This series consists of twelve sizes of connectors with contact arrangements for 2, 3, 5, 7, 11, 14, 20, 26, 34, 42, 50 and 75 size 20 contacts (.039 (1) dia.). These connectors are characterized by a high density of size 20 contacts in a compact volume. The MB series presents three types of terminations : @ solder pot for wire (AWG 20 max) @ straight solder pin for PCB @ right angle solder pin for PCB These connectors can be fitted with rack guides or fixed or rotating jackscrews at each end. Wires and soldered terminations for wire can be protected by either top or side entry hoods or by potting covers for 2 to 14 contacts connectors.
