Dubox® 2.54mm Connectors

Amphenol FCI Dubox® 2.54mm Connectors feature a pre-stressed, dual-beam design that enables low insertion force. The four-wall contact design of the Dubox 2.54mm Connectors provides signal protection. This Amphenol FCI series offers through-hole and surface-mount options, including single- or double-row in straight or right-angle orientations from two to 104 positions. Dubox 2.54mm components feature a 3A maximum current rating per contact. The series is ideal for a variety of industrial and instrumentation applications.
