5749069-2 is a 26-position vertical receptacle header from the AMPLIMITE .050 Series, designed for high-density D-subminiature connector applications. This connector features through hole tails for PCB mounting and includes rails and latchblocks for secure mating. The housing is made of thermoplastic with 94V-0 flammability rating and is SMT compatible, while contacts are phosphor bronze with duplex gold plating (minimum 0.00076 mm) on the mating end and tin on the solder end. The connector utilizes a compact 0.050 x 0.100 inch (1.27 x 2.54 mm) grid spacing, making it ideal for space-constrained applications requiring reliable high-density interconnections in data and device systems.
