- Pack of 8 self-adhesive PCB standoffs
- Board bottom rests 0.5" (12.7mm) above the enclosure floor
- 0.9" (23mm) overall height
- 0.71" (18mm) square self-adhesive mounting pad
- Suggested material thickness 0.0625" (1.6mm) max., hole diameter 0.156" (4mm)
- Tough white nylon
- RoHS and REACH compliant
The 1421PCB2-8 is an 8-pack of 1/2" printed circuit board standoffs from the 1421PCB Series, for electronics designers and builders who need more clearance beneath a PC board than the 1/4" version offers. Each standoff uses a square mounting pad with self adhesive to attach to the enclosure floor.
The standoff height is 0.50 in (13 mm), with the bottom of the P.C. board resting 0.5" (12.7mm) above the enclosure floor. The overall height is 0.9" (23mm), and the square mounting pad is 0.71" (18mm). The standoffs are made from tough white nylon.
For the board being mounted, the manufacturer suggests:
- Material thickness of 0.0625" (1.6mm) max.
- Hole diameter of 0.156" (4mm)
The 1421PCB2-8 is RoHS compliant and REACH compliant, and the 8-pack has a shipping weight of 0.03 lbs (0.01 kg).
Compared with the 1/4" standoffs (1421PCB1-8 and 1421PCB1-100), which hold the board 0.25" (6mm) up with a 0.65" (17mm) overall height, the 1421PCB2-8 doubles the clearance under the board, while keeping the same 0.71" (18mm) self-adhesive pad and the same hole and thickness guidelines. For larger builds, the same 1/2" standoff is available in a 100-pack as 1421PCB2-100.
Ideal For
- Mounting PC boards with 0.5 in clearance in small enclosures
