104074-4 is a right angle header assembly designed for PCB-to-board interconnect applications within the AMPMODU System 50 series. This single row header features side and end latches for secure mating connections. The housing is constructed from black thermoplastic material with copper alloy contacts, where contact areas are plated with 0.000030 inch gold over 0.000050 inch nickel, and solder tails are plated with 0.000150 inch tin-lead. The connector utilizes a 0.050 inch pitch spacing with recommended PCB hole diameters of 0.022 inch for contacts and 0.037 inch for mechanical hold-down features. This header assembly is suitable for applications requiring reliable board-to-board connections with positive latching mechanisms.
