ITT Cannon KPT/KPSE MIL-DTL-26482 Series I Connectors


INTERMATEABLE WITH SOURIAU CONNECTORS & ALL MIL-DTL-26482 SERIES I

ITT Cannon KPT / KPSE series MIL-DTL-26482 series I connectors offer high-density contact arrangements in a miniature circular connector. The KPT series (thru-bulkhead) offers a range of solder cup connectors while the KPSE series offers crimp connectors. These series are qualified to MIL-DTL-26482 and are intermateable with VG95328 connectors, Souriau connectors and all MIL-26482 series I connectors. The ITT Cannon KPT / KPSE series is used in a range of harsh environment industrial applications. Mil spec prefixes include: MS3110, MS3112, MS3114, MS3116, MS3119, MS3120, MS3122, MS3124, and MS3126. ITT Cannon proprietary prefixes are KPT and KPSE.

FEATURES

ITT CANNON KPT SERIES 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, exceeding the wire sealing requirements of MIL-DTL-26482.

  • 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 22 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.
