M40 1.0mm Board-to-Board SMT Connectors

Harwin M40 1.0mm Board-to-Board SMT Connectors feature a range of surface-mount pin headers and sockets designed to provide a cost-effective solution for secure and highly reliable PCB-to-PCB connections. The M40 series offer a low-profile design and a dual-beam contact system, allowing designers to reduce PCB sizes without sacrificing connector reliability. The small contact spacing of 1.00mm makes Harwin M40 connectors ideal for use in confined spaces such as handheld devices, consumer electronics, and industrial control systems.
