Tech Lowdown– DR105 DIN Rail Clips

Do you want to mount your devices to DIN rail, but they don’t have DIN rail clips? If your device has flanges or mounting ears, you can use the Sealevel DIN rail mounting clips (Item# DR105) to make virtually any device DIN rail compatible.

The durable plastic clips mount to flanges with included self-tapping screws. Two sets of different length screws are included that allow the clips to be installed on thick plastic or thin metal flanges. Once installed, the devices are then easily mounted to all profiles of 35mm wide DIN rail (commonly called “Top Hat” rail).

For convenient field installation and service, order the DR105 DIN rail clips to easily mount your I/O devices near your industrial control equipment.
