The FH28K Series connectors are designed for high-heat applications, offering superior reliability and operability. With a 125 heat resistance, robust design, and flip-lock mechanism, these connectors are ideal for demanding environments such as automotive. They are compatible with 0.3mm FPC/FFC thickness and offer enhanced retention force, pick & place mounting, and halogen-free compliance.
