Samtec Inc. Header, 2.54Mm, Though Hole Vertical, 54 Position; Connector Systems Samtec HTSW-127-20-T-D

The Header, 2.54mm, Through Hole Vertical, 54 Position (part number 85T2084) is designed for board-to-board applications with a pitch spacing of 2.54mm. It features a two-row configuration with a total of 54 contacts, suitable for through-hole mounting. The insulator material is black glass-filled polyester, and the terminals are made of phosphor bronze with options for gold or tin plating over nickel. This connector operates within a temperature range of -55¬8C to +125¬8C when gold plated, and -55¬8C to +105¬8C with tin plating. The voltage ratings vary depending on the mating connector, with a maximum of 550 VAC when mated with SSW connectors. The current rating per pin varies based on the mating connector, with values ranging from 4.3 A to 6.3 A. The product is RoHS compliant and lead-free solderable, making it suitable for environmentally conscious designs. Engineers should consider this header for applications requiring reliable connections in compact spaces, particularly where high-density pin configurations are necessary.
