AMPFOIL ULTRA Connectors

TE Connectivity AMPFOIL ULTRA Connectors are designed for Flexible Flat Cable (FFC) and Flexible Printed Circuit (FPC) applications. These connectors feature a noteworthy plug design that allows the parallel installation of two foils, significantly increasing signal density. The AMPFOIL ULTRA connectors come with a 1mm pitch for the foils and a compact 0.5mm pitch on the PCB layout, which dramatically conserves board space. These connectors offer a positive locking mechanism that helps to ensure the connection remains secure, preventing accidental unmating or loosening from unexpected pull forces in any direction. The AMPFOIL ULTRA connectors plug features a transitional sinking surface, making it easier to unlatch when needed. These connectors meet the rigorous vibration performance standards of LV 214, achieving Severity 2.
