The 1421PCB1-100 is the 100-piece pack of the 1/4" printed circuit board standoff in the 1421PCB Series. It suits OEM engineers and production teams mounting PC boards in enclosures in quantity; the same standoff is offered as an 8-pack under 1421PCB1-8 for smaller jobs.
Each standoff has a 0.71" (18mm) square mounting pad with self adhesive. The standoff height is 0.25 in (6 mm), meaning the bottom of the P.C. board would rest 0.25" (6mm) above the enclosure floor, and the overall height is 0.65" (17mm). The standoffs are made of tough white nylon.
Guidelines from the manufacturer for the board being mounted:
- Suggested material thickness: 0.0625" (1.6mm) max.
- Suggested hole diameter: 0.156" (4mm)
The 1421PCB1-100 is RoHS compliant and REACH compliant. The 100-piece pack has a shipping weight of 0.24 lbs (0.11 kg).
If your design needs more room under the board for components or wiring, the 1/2" standoffs in the same series hold the board 0.5" (12.7mm) above the floor with a 0.9" (23mm) overall height; they are sold as 1421PCB2-8 and 1421PCB2-100. For 1/4" clearance in bulk, order the 1421PCB1-100.
