TE Connectivity FASTON and PIDG FASTON Connectors offer the advantage of a completely protected terminal and a wire crimp with comparable electromechanical performance to open barrel “F” crimp FASTON Terminals. FASTON and PIDG FASTON Connectors consist of a tin-plated brass FASTON body with full nylon insulation. A metal support sleeve fitted over the wire termination barrel provides circumferential insulation support to the wire after crimping. This allows the wire to be bent in any direction, without fraying the wire insulation or breaking the conductor. Typical applications include power supplies, automotive, motors, instrumentation and terminal blocks.
