SMB connectors offer snap-fit coupling for quick connect/disconnect, making them ideal for circuit miniaturization. They are available in commercial or high reliability versions, with 50 and 75 Ohm MIL-Type connectors. Straight plugs and jacks are completely crimp terminated for fast and easy cable assembly, featuring low VSWR. These connectors are designed for use with standard military, commercial, or Tyco Electronics tooling. Tyco Electronics' 75 Ohm BT 43 SMB Connectors feature unique spring mating with snap-fit couplings and are intermateable with 75 Ohm SMB MIL-C-39012 connectors, offering reliable dual crimp cable terminations.
