AdvancedTCA® Faceplate Fastening Solutions (Bulletin FPS ) AdvancedTCA® (ATCA) specifications for telecom rack systems require two clinching fasteners: a self-clinching alignment pin and a captivated screw. The PEM® type TPXS™ pin meets the ATCA PICMG 3.0 specifications for a 3mm alignment pin. The 15° tapered point makes engaging the mating hole easy. PEM® captive floating retention screws, with M3 threads and 0.51 mm of radial float, offer an ATCA style mounting solution. These thumb screws provide the added advantage of an anti cross-thread feature making thread engagement quick and easy. Types PF11M and PF12M provide retainer shoulder for enhanced visual verification of installation. View Product Specifications PDF Click here for CAD file.
