What are 35 mm DIN rail dimensions? · Hardware · basis: EN 60715 top-hat rail TS35 × 7.5
- sizes
- 6 in table
Notes
- 35 mm wide (±0.3), 7.5 mm deep (15 mm deep version exists), 1 mm steel; lips 1 mm thick leave a 27 mm inner width. Mounting slots on 25 mm pitch down the centre.
- A printed clip hooks one lip and snaps over the other: the flange is 35.0 wide, so the clip's opening is 35.3 and the hook depth 1.0–1.2 mm with a spring tab.
- Files: the rail profile at 100 and 200 mm, for checking a printed enclosure clip.
