SSMC Connectors

SSMC Connectors

SSMC connectors are ideal for limited-space applications that require the security of a threaded coupling mechanism..

They are best used with semi-rigid cables or miniature flexible cables in demanding applications up to 12.4 GHz

Features and Benefits
  • Micro miniature size- up to ⅓ smaller than SMC
  • Secure threaded coupling ideal for applications where vibration resistance is important
  • Avionic Equipment
  • Handheld Devices
  • Missile Systems
  • Weapon Control Systems
