Amphenol PT / PT-SE Connectors (MIL-DTL-26482 Series I)

Amphenol PT / PT-SE Connectors (MIL-DTL-26482 Series I)

EXTREME EXPOSURE MINI-CIRCULAR CONNECTORS

The Amphenol PT series and PT-SE series connectors (MIL-DTL-26482 Series I) provide high-density contact arrangements in a circular shell. PT offers solder contacts, PT-SE offers high-performance crimp contacts, and PT-CE offers a commercial crimp option. These circular connectors provide quick-disconnect bayonet coupling for rapid mating and unmating, and several mounting styles and shell sizes. For full product details on Amphenol PT, PT-CE and PT-SE series connectors, see our specifications below.

Get shopping! Mil Spec prefixes include MS3110, MS3112, MS3114, MS3116, MS3119, MS3120, MS3122, MS3124 and MS3126. Amphenol proprietary prefix is PT.

FEATURES

AMPHENOL PT/PT-SE 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˚F to +257˚F (-55˚C to +125˚C) under the harshest possible conditions.

  • Wide Range of Wire Gauges and Current-Carrying Capacity
    Up to 23 amps with wire gauges from 24 to 12 AWG wire.

  • Resilient insulator & grommet
    A resilient neoprene insulator and integrated rear wire sealing grommet guarantees a liquid-tight assembly. Crimp contacts that can be inserted from the rear of the connector are available. Solder contacts are permanently bonded into the insulator.

  • Solder or crimp gold-plated contacts
    PT connector contacts are gold-plated per MIL-G-45204 type II. PT-CE commercial crimp contacts are not military-approved, but the PT-SE crimp contacts are built in accordance to MIL-C-39029. Both types of contacts are crimped with the standard M22520/1 crimp tool. Socket contacts are closed to eliminate damage from test probes and to help prevent misaligned pins during engagement. Contact insertion is from the rear of the connector. When the contact is fully inserted, it snaps securely into 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.

  • Agency Approvals
    MIL-DTL-26482 Series I, UL #E115497, VG95328 or HE301

3.7.4 JAN and J Marking. The United States Government has adopted and is exercising legitimate control over the certification marks “JAN” and “J”, respectively, to indicate that items so marked or identified are manufactured to, and meet all the requirements of specifications. Accordingly, items acquired to, and meeting all of the criteria specified herein and in applicable specifications shall bear the certification mark “JAN” except that items too small to bear the certification mark “JAN” shall bear the letter “J”. The “JAN” or “J” shall be placed immediately before the PIN except that if such location would place a hardship on the manufacturer in connection with such marking, the “JAN” or “J” may be located on the first line above or below the PIN. Items furnished under contracts or orders which either permit or require deviation from the conditions or requirements specified herein or in applicable specifications shall not bear “JAN” or “J”. In the event an item fails to meet the requirements on this specification and the applicable specification sheets, the manufacturer shall remove completely the military PIN and the “JAN” or the “J” from the sample tested and also from all items represented by the sample. The “JAN” or “J” certification mark shall not be used on products acquired to contractor drawings or specification. The United States Government has obtained Certificate of Registration Number 504,860 for the certification mark “JAN” and Registration Number 1,586,261 for the certification mark “J”.
