The 1421PCB1-8 is an 8-pack of 1/4" printed circuit board standoffs from the 1421PCB Series. Each standoff has a square mounting pad with self adhesive, so it sticks to the enclosure floor and holds a PC board above it. It is aimed at electronics designers, hobbyists and OEM builders fitting boards into small cases.
The standoff height is 0.25 in (6 mm): the bottom of the P.C. board rests 0.25" (6mm) above the enclosure floor. Overall height is 0.65" (17mm), and the square mounting pad measures 0.71" (18mm). The part drawing shows the pad as 17.90 mm [.70] square and the overall height as 16.30 mm [.64].
The manufacturer gives these guidelines for the board being mounted:
The 1421PCB1-8 is RoHS compliant and REACH compliant. The 8-pack has a shipping weight of 0.03 lbs (0.01 kg).
The same 1/4" standoff is also sold in a 100-pack as 1421PCB1-100, which suits production quantities. For more clearance under the board, the 1/2" standoffs (1421PCB2-8 and 1421PCB2-100) have a 0.9" (23mm) overall height and raise the board 0.5" (12.7mm) above the floor.
