Sealcon Connectors

Sealcon_Hummel copy_2

Sealcon circular connectors include: M16, M23, M40, RJ45, PoE, Twilock and Twintus. These connectors are field assembly-ready, meaning no special tools are required to insert or extract the contacts. They are also modular in order to meet a variety of configurations. They have a reliable connection due to the contacts’ low plug-in force and high mating cycles. The pre-tinned contacts mean these connectors are a more Reliable, Faster and Safer means of soldering. The Inserts are for all types of contacts including Crimp, Solder & Dip Solder.

Sealcon connectors have the following benefits:

  • Radially arranged copper beryllium spring contacts
  • The outside contour of the socket results in a perfect concentric alignment during connection
  • Best conductivity due to gold-plated contact area
  • Reduced assembly time due to tinned soldering ends

Typical Industries:

  • Automation
  • Automotive
  • Diagnostic
  • Hazardous
  • Marine
  • Medical
  • Motors
  • Packaging
  • Robotics
  • Sensing
  • Telecom
  • Transportation
