Samtec Inc. Header, 2.54 Mm, Through Hole, 2 Rows, 40 Contacts; Connector Systems Samtec MTSW-120-05-G-D-130

The Header, 2.54 mm, Through Hole, 2 Rows, 40 Contacts (part number 94P0234) is designed for board-to-board connections with a pitch spacing of 2.54 mm. It features a total of 40 contacts arranged in two rows, making it suitable for applications requiring compact and reliable connections. The header is constructed with modified .025" square posts, allowing for custom post heights to accommodate various design requirements. The insulator material is black glass-filled polyester, and the terminal material is phosphor bronze, with plating options available in gold or tin over nickel. This component operates within a temperature range of -55 ¬8C to +125 ¬8C when gold-plated, and -55 ¬8C to +105 ¬8C with tin plating. The product is RoHS compliant and offers lead-free solderability for specific configurations. Engineers should consider this header for projects that require a robust and flexible connection solution, particularly in environments where temperature extremes are a factor.
