Hermetic MIL-DTL-26482, Series 2

hermetic-26482-w-coax FEATURES AND BENEFITS

Three shell styles are available in the hermetic PT bayonet series:
  • PT1H (MS3113H)
  • PT02H
  • PT07H (MS3114H)

These hermetic connectors are only available with solder cup or flat eyelet pin contacts in the MS/PT version. Socket & PDB tails are available in proprietary PT versions. Other design characteristics of the PT hermetic connector series are as follows:
  • Shell size 8 - 24 (tin plated)
  • Contact counts - 2 - 61. Refer to pages 4 and 5 for insert availability for hermetic from Miniature Cylindrical Connectors Catalog 12-070-15
  • Current - 5.0 amp each #20 contact, 10 amp each #16 contact, 17 amp each #12 contact
  • Contacts are tin plated for PT; gold is optional
  • Dielectric Withstanding Voltage (sea level) - 1500 volts (RMS) 60 cps, Service Rating I, 2300 volts (RMS) 60 cps, Serice Rating II
  • Compression glass inserts, permanently lettered
  • Helium leakage - less than 1.0 x 10-6 cc/sec. at 15 psi differentail
  • Physical Shock - 100 G's
  • Vibration - exceeds MIL-E-5272 Procesure II
  • Thermal Shock - no deterioration or failure after 5 cycles at -55°F to +257°F
  • Intermateability - mates with MS3116 and PT06

Hermetic MIL-DTL-38999 Series III



  • EMI Shielding - solid metal to metal coupling, grounding fingers, electroless nickel plating, and thicker wall sections provide superior EMI shielding capability of 65dB minimum at 10 GHz
  • Contact Protection - recessed pins in the 100% scoop proof connector minimize potential contact damage
  • Mosture Resistance - improved interfacial seal design helps prevent electrolytic erosion of contacts
  • Corrosion Resistance - shells of stainless steel or cadmium over nickel plating withstanding a 500 hour salt spacy exposure
  • Vibration/Shock - operates under severe high temperature vibration, through 200°C
  • Firewall Capability - available in a stainless steel shell, class RK, RS
  • Lockwiring Eliminated-unique, self-locking, quick coupling connectors eliminates lockwiring
  • Quick Coupling-completely mates and self-locks in a 360° turn of the coupling nut
  • Inventory supported Commonality - uses standard MIL-DTL-38999 contacts, application tools, insert arrangements
  • Electostatic Discharge Protection (ESD)-protection for sensitive circuitry without diodes, varistors, etc., with the use of the Faraday Cage principal which shunts high voltage, high current discharge events
  • Ground Plane Connectors - with metallic insert for common grounding of coax, triax or twinax contact outer shield
  • Contact Options - available in solder, wire wrap and PCB tail
  • Hermetic- air leakage limted to 1 x 10-7 CM³ per second optional

Hermetic Aquacon



The Amphenol® AJ Aquacon Series of connectors has been designed to provide maximum service in oceanic or fluid immersion applications:

  • 1500 PSI capability
  • "O" ring sealing, thread
  • Threaded coupling
  • Visual mating indication
  • Design flexibility

A specially designed aluminum bronze coupling nut and type 316 stainless steel shells resist corrosion and provide a pressure withstanding connector. Positive threaded coupling, "O" rings, and a color band visual indicator assure sealing and proper mating.

A rear accessory threaded provides for the use of EMI hardware or molding adapters.

The AJ series is available in several different shell styles, with numerous MIL-DTL-38999 insert patterns. Hermetically sealed (1 x 10-7 He/sec leakage rate) arrangements are also available.
