5352131-1 is a 2mm Hard Metric PCB mount connector assembly designed for board-to-board interconnection applications. It features a Type B, 22 Column configuration with 110 total positions arranged in 5 rows, mounted at a right angle to the PCB. The connector utilizes gold-plated (30 µm) phosphor bronze contacts with a feedthrough post length of 3.30 mm, and employs tin over nickel termination end plating for reliable signal transmission. This connector is RoHS and ELV compliant, making it suitable for modern electronic systems requiring robust interconnection in backplane and midplane applications where standardized 2mm Hard Metric spacing is required.
