RJ45 Sealed Feedthrough

RJ45 Sealed Feedthroughs are standard stock items in NW40 / KF40 and FS16.  If you require more RJ45’s sealed into a larger flange, we can assist you with custom requirements too.

Please see below for further information and contact our team if you require a quotation or a drawing.

RJ45 Sealed Feedthrough

Whether you require an RJ45 sealed feedthrough (RJ45 Jack, Ethernet, CAT5, 8P8C) in an FS16, NW40/ KF40 or a different flange, we can assist you.

If one of our RJ45 feedthroughs in stock doesn’t fit your application, we can work with you to find a cost-effective solution with a short lead time by creating a custom seal for your design.  We have helped to create thousands of custom hermetic connector seals which can withstand high pressure and temperatures ranging from -100⁰C to 250⁰C.

Testing RJ45 Sealed Feedthroughs

Every hermetic connector seal goes through the same rigorous testing to ensure top quality products are guaranteed.  They all are dimensionally checked, continuity tested, hipot tested and go through a helium leak test.

Jacarem Process

Most custom pressure feedthrough and vacuum feedthrough seals begin with an e-mail or phone call from a customer.  Whether you require a prototype, low volume or high volume, our experienced engineering team will oversee every custom hermetic seal project from the early design stage through to the manufacturing process.  If you have a specific connector, fiber optic, cable or wire in your system that needs to be sealed, we can use it to create your custom hermetic seal.

We will require some information from you, such as:

  • Pressure or Vacuum level
  • Temperature range
  • Gases or liquids present
  • Electrical requirements

Custom Hermetic Connector Seal Types

It is impossible to convey the vast variety of connectors that our engineering team have sealed.  As it stands, there has never been a connector that our team have been unable to seal, so whatever your connector, please contact our team today for your RJ45 sealed feedthrough.
