The SA120 is a low-profile adhesive standoff with a 0.120" standoff height. It securely attaches your PCB to a flat surface. The post inserts into a 0.125" mounting hole. The post includes a locking tab that secures the PCB when inserted. It can be used with 1/16" or 1/32" thick PCBs.
The 0.6" x 0.8" rectangular base is offset to allow the base to be underneath the board when the mounting hole is close the to PCB edge. The offset base provides a large sticking surface while permitting the PCB to be mounted in tight spaces or close to walls. This can be useful when working with small enclosures. High-quality 3M brand double-sided tape secures the standoff to a flat surface.
