DIN rails and mounting hardware are used on computer boards. DIN is an acronym for Deutsche Institute fuer Normung, a German standardization body and member of the International Standards Organization (ISO). DIN rails and mounting hardware are standard mounting equipment for a variety of electronic components, including terminal blocks to connect wiring. DIN rails and mounting hardware are internationally approved, industry standard hardware for a vast array of components made by computer manufacturers. DIN rail terminal blocks also offer grounding and disconnecting capability and provide self-locking clamps to ensure a tight connection.
