Hirose FunctionMAX FX20 Series Straight Surface PCB Socket 40-Contact 2 Row 0.5 mm Pitch Solder

Hirose FX20-40S-0.5SV FunctionMAX FX20 Series straight surface PCB socket is a high-quality board-to-board connector featuring 40 female contacts arranged in 2 rows with a 0.5 mm pitch designed for surface mount technology. It is engineered with a unique floating structure that absorbs mounting misalignment errors, significantly reducing stress on solder joints and preventing cracking, which decreases the need for rework in industrial and automotive assembly processes.

The connector supports a rated current of 0.5A per contact and a voltage rating of 50V, making it suitable for demanding electrical applications. Contacts crafted from bronze and plated with gold ensure excellent conductivity and corrosion resistance, while the housing made from Liquid Crystal Polymer offers mechanical robustness and excellent insulation properties.

The FX20 socket operates reliably across a wide temperature range from -55°C to 85°C, addressing rigorous conditions commonly encountered in industrial, automotive, and instrumentation use cases. Its 15 mm stacking height and straight orientation facilitate flexible, compact PCB stacking designs with enhanced alignment accuracy, supported by large guiding features to prevent incorrect insertions.

Designed with dual beam self-cleaning contacts, this PCB socket guarantees stable electrical connections even under high vibration environments prevalent in automotive, broadcast, and industrial equipment. Its board-to-board connector system allows easy integration with FunctionMAX FX20 headers to achieve secure, high-performance inter-board communication.

This socket is widely applicable across automotive electronics, broadcast equipment, base station transceivers, industrial machinery, measuring instruments, medical devices, printers, copiers, projectors, and smart metering systems, where reliability and vibration resistance are critical. The robust design enhances operational longevity, minimizes downtime, and supports demanding industrial standards.
