Hirose FX8 Series Straight Surface PCB Socket 140-Contact 2 Row 0.6 mm Pitch Solder FX8-140S-SV(21)

Hirose FX8-140S-SV(21) is a straight surface mount PCB socket featuring 140 female contacts arranged in 2 rows with a pitch of 0.6 mm. This connector is part of the FunctionMAX FX8 series, designed to provide high-speed board-to-board connections with excellent signal integrity up to 3.125 Gbit/s and reliable mating alignment.

The socket utilizes a bronze contact material with gold plating to ensure electrical continuity and resistance to corrosion. Its optimized spring deflection contact design increases durability and enhances connection reliability over time. The built-in mating guide ribs provide a self-alignment tolerance of ±0.6 mm, allowing for easier installation and design flexibility.

Built to operate reliably in temperature ranges from -55°C up to 85°C, this PCB socket supports applications across various industries such as servers, broadcast equipment, industrial control machinery, medical devices, and point-of-sale terminals. It is rated for 100 V and a current capacity of 400 mA, suitable for typical electronic power and signal transmission requirements.

The socket is surface mount type with SMT coplanarity tolerance below 0.1 mm at the solder area, improving solder joint quality on PCBs. Stacking height of 16 mm supports a broad range of board-to-board spacing options for design versatility. Guide posts located at the bottom with varying diameters further aid in precise PCB alignment and prevent connector misinsertion during assembly.

High-speed transmission capability up to 3.125 Gbit/s. Built-in mating guide ribs allow ±0.6 mm self-alignment tolerance and easy mating. Contact spring deflection design provides increased reliability and durability. Surface mount with SMT coplanarity tolerance less than 0.1 mm for quality soldering.

Wide stacking height of 16 mm accommodates diverse board spacing designs. Gold plated bronze contacts for enhanced conductivity and corrosion resistance. Rated voltage 100 V and current 400 mA for reliable performance. Operating temperature range from -55°C to +85°C for industrial applications.

Applications include servers, broadcast equipment, industrial machinery, medical devices, and POS terminals.
