19 Pin Circular (Mil-C-26482) Components

AGP's 19-Pin circular instrumentation hermetic feedthroughs are constructed with a pin arrangement per Mil-C-26482 specification. Nineteen gold-plated pins are arranged in a straight-through pin-to-pin design, hermetically sealed and electrically insulated into a stainless steel shell (19 pin feedthrough) using the latest in glass-ceramic bonding technology.

Mil-C-26482 feedthroughs and cable assemblies are sold individually or as complete kits, wherein each kit contains a 19 pin feedthrough and both vacuum and air side cable assemblies. Vacuum compatible cable assemblies are fitted with PEEK (polyether-etherketone) polymer connectors and Kapton® insulated ribbon cable to meet the demands of ultrahigh vacuum environments. Vacuum connector includes a captured stainless steel socket head screw that securely locks it to a mating feedthrough. Captured in-vacuum screws are vented where required and the feedthrough’s screw-boss also doubles as a polarizing key. Feedthrough’s air-to-vacuum pin position is identified with a permanent surface mark to aid pin assignment. Air-service cable assemblies have standard bayonet type Mil-C-26482 circular connectors.

Notes 
  1. Electrical ratings are maximum test values, with vacuum side at ≤ 1x10-4 Torr. Feedthroughs are intended for instrumentation applications carrying low level signal voltage and current.
  2. For proper heat dissipation, a maximum of 20% of the pins on a feedthrough may carry the maximum pin current at any given time.
  3. PEEK is a polyether ether ketone thermoplastic.
  4. Leak tested to 5x10-10 Standard cc/sec of He.
  5. Overall assembly ratings must be adjusted to that of its lowest rated component. For cryogenic service, the lowest recommended temperature is -200°C
  6. Unless designated a 'kit,' connectors and cable assemblies are not included with feedthrough and must be purchased separately.
