Top hat section, type O, or type Ω, with hat-shaped cross section.There are three major types of DIN rail: The original concept was developed and implemented in Germany in 1928, and was elaborated into the present standards in the 1950s. The term derives from the original specifications published by Deutsches Institut für Normung (DIN) in Germany, which have since been adopted as European (EN) and international (IEC) standards. Although metallic, they are meant only for mechanical support, and are not used as a busbar to conduct electric current, although they may provide a chassis grounding connection. These products are typically made from cold rolled carbon steel sheet with a zinc-plated or chromated bright surface finish. Note the release loops at the top of the mounted devices which unclip them.Ī DIN rail is a metal rail of a standard type widely used for mounting circuit breakers and industrial control equipment inside equipment racks. The example in the photos was printed on a Prusa i3 Mk2 using Boots Industries orange PLA.ĭownloadable STEP files are included if you want to make modifications. The small gaps between the parts of the spring clip are all at least 0.4mm, so this should be printable on most machines.
Other similar size screws would likely work fine.
Like the original, the board is secured into the enclosure with M3 x 6mm machine screws, and the two halves of the enclosure are secured together with M3 x 16mm machine screws. The case was based on the Pi 3 bottom and universal Pi 2/3 top, so it should suit Pi 3 or Pi 2. A front-accessible notch at the bottom allows releasing the spring clip in the usual way with a fingernail or screwdriver. Hang it over the top of the rail then rotate downwards and it will clip over the bottom. The case clips on the rail in the usual way. It therefore takes much less space on the rail than other cases that mount the Pi flat against the rail. The enclosure mounts the Raspberry Pi on the rail vertically, sideways on, with SD card slot facing up and connectors facing down and to the front.
A remix of 0110-M-P's excellent Raspberry Pi case to remove the VESA mounting tabs and replace with a DIN rail mount.
