0.635mm Pitch Board to Board Socket, SMT, 4mm Stack Height
Introduction:
The 0.635mm Pitch Board to Board Socket is a high-density SMT female connector designed for reliable board-to-board interconnection in compact electronic devices. Featuring a vertical mating orientation and a 4mm stack height, it is available in 20, 30, 40, and 50 positions to accommodate various design requirements while maximizing PCB space utilization.
Manufactured with copper alloy contacts and gold flash plating, this connector provides stable electrical performance, low contact resistance, and enhanced durability. The high-temperature thermoplastic insulator ensures excellent mechanical strength and dimensional stability during SMT assembly processes, making it suitable for demanding industrial and consumer electronic applications.
Designed for dependable operation in harsh environments, the connector supports an operating temperature range of -40°C to +85°C and complies with UL 94 V-0 flammability requirements. Its dual-row configuration and fine 0.635mm pitch enable high signal density while maintaining secure and reliable connections for modern electronic systems.
