316918-1 is a PCB mount hermaphroditic connector designed for vertical board-to-board signal applications. This 240-position, 2-row connector features a 0.6 mm centerline pitch with gold-plated mating contacts and nickel underplating for reliable electrical connections. The connector has a stack height of 4 mm and connector height of 8.88 mm, with a housing made from Liquid Crystal Polymer (LCP) material. It operates within a temperature range of -55°C to 85°C and supports an operating voltage of 10 VAC. The surface mount design with solder peg retention and positioning bosses makes it ideal for high-density PCB interconnect applications requiring stackable, parallel board-to-board configurations.
