Introduction to Hirose FH55-31S-0.5SH connector product (series)
The Hirose Electric FH55 series FPC connector is a high-precision, ultra-thin interconnect device, specifically designed for high-density electronic equipment. The connector is mounted using surface mount technology (SMT), with a right-angle installation, suitable for FPCs with a thickness of 0.30mm, providing an ideal solution for compact circuit design. The FH55 series has 31 pins, with a pitch of 0.50mm, and a board height of only 1.50mm, supporting a rated voltage of 50V and a rated current of 0.5A, and can operate stably in an environment of -55°C to 85°C. Its zero insertion force (ZIF) design with trigger locking mechanism ensures easy installation and reliable connection, while the fixed tail design enhances welding stability. The contacts of this series are made of phosphor bronze and are electroplated with gold of 1.25µin (0.03µm), enhancing conductivity and corrosion resistance. The housing and actuator are made of heat-resistant liquid crystal polymer (LCP), meeting the UL94 V-0 flame retardant standard. The FH55 series supports 20 mating cycles and is widely used in precision application scenarios such as consumer electronics, medical equipment, and industrial control.
