Series I connectors
APPLICATIONS
• Commercial Aerospace
• Military Aerospace
• Military Ground Vehicles
TE Connectivity’s DEUTSCH AFD series connectors are MIL-DTL-26482
Series II-qualified connectors. They feature bayonet coupling and
rear release contacts in a miniature circular connector system with
environmental sealing.
This series features four receptacle mounting styles: square flange,
wide square flange, cable connecting, and single-hole mount. Plugs are
available with and without EMI fingers.
