Glossary of Terms Used

  • Front Mounted Terminal Block- An accessory solution that connects directly to the front of a module. These accessories can be shield or unshielded, they also can allow for the user to directly access the signal on the front of the module or may require additional cabling or accessories to access the device signals. Click here for an example.
  • Remote Terminal Block- An accessory solution that requires a cable to connect to the module. This accessory can be connected, using the cable, directly to the module, or it can be connected, using a cable, to additional accessories. Click here for an example.
  • Micro Coaxial (MCX)- Industry standard cable characterized by an inner conductor and an outer shielding. Click here for an example.
  • SubMiniature Version A (SMA) - A quick connect/disconnect for coaxial cables to assist in noise reduction, this connector features a threaded barrel and hex nut for mating. Click here for an example.
  • SubMiniature Version B (SMB) - A quick connect/disconnect for coaxial cables to assist in noise reduction, this connector is a smaller size and features a latching mechanism. Click here for an example.
