HIGH-DENSITY MINIATURE CIRCULAR INTERCONNECTS FOR THE HARSHEST ENVIRONMENTS
ITT Cannon KPT / KPSE / KPTC connectors offer high-density contact arrangements in a miniature circular connector. Available in 10 shell sizes, with 40 layouts ranging from 2 to 61 contacts; the KP family features a secure 3-point locking system and five-way polarization for precise alignment. The KPT series (thru-bulkhead) offers a range of solder cup contacts while the KPSE connector offers crimp contacts. Both series are engineered to be comparable to MIL-DTL-26482 and are interminable with VG95328 connectors and 26482-Style Series I connectors.
The ITT Cannon KPT / KPSE connector series also offers a comprehensive range of backshells, accessories, and plating options making it an ideal solution in harsh environment applications.
Features
Rugged Shell Aluminum alloy shell and hardware create a rugged connector with minimal weight. These connectors have been used extensively in commercial, military, and aerospace environments. Standard shells accept all MIL-DTL-26482 accessories.
Environmentally-Sealed Complete moisture sealing is achieved by combining four seals: shell, peripheral, interfacial, and wire. Wire seal is accomplished by multiple ripple design.
Resistant to Military Environments These connectors will operate in temperatures from -67˚ to +257˚F (-55˚ to +125˚C) under the harshest possible conditions.
Wide Range of Wire Gauges and Current-Carrying Capability Up to 13 amps with wire gauges from size 24 up to size 16 AWG.
Resilient Insulator & Grommet A resilient polychloroprene insulator and integrated rear wire sealing grommet guarantees a liquid-tight assembly. Crimp contacts are available that can be inserted from the rear of the connector. Solder contacts are permanently bonded into the insulator.
Solder or Crimp Gold-Plated Contacts Both solder (KPT) and crimp (KPSE) contacts are available. Both are gold-plated per MIL-G-45204 Type II. KPSE crimp contacts are designed to MIL-C-39029 and can be crimped with the standard M22520/1 crimp tool. Socket contacts are closed to eliminate damage from test probes and to help correct misaligned pins during engagement. Contact insertion is from the rear of the connector. When the contact is fully inserted, it snaps securely into metal retention tines embedded in the insulator. Contact extraction is accomplished from the front with the proper extraction tool. Pressing the tool plunger pushes the contact out through the rear of the connector.
