FDD insulated female terminals provide a spring-contact connection to flat male tabs. The crimp arrangement supports the conductor and insulation, while the receptacle holds the matching tab for serviceable electrical connections.
Match both tab thickness and width. Typical applications include control equipment, motor wiring and HVAC electrical assemblies.
Insulation colors correspond to the conductor groups: red for 0.5-1.5mm², blue for 1.5-2.5mm² and yellow for 4-6mm².
All dimensions below are in mm. d and D identify barrel dimensions; B, L and H retain their dimensional symbols.
