71-2-R Description

Short technical summary and product information.

The 71-2-R is a right-hand PCB card ejector from CALMARK CORPORATION's Series 71, designed for use with 1/16" (1.6 mm) thick printed circuit boards. It is constructed from 6061-T6 aluminum alloy per QQ-A-250/8, with a customer-specified finish. The ejector weighs 1.42 g and has an overall length of 38.1 mm and width of 25.4 mm.

 

This ejector provides a minimum extraction travel of 11.4 mm with a nominal mechanical advantage of 4.5:1, facilitating easy insertion and removal of PCBs. Two extractors (one left and one right) are recommended per board. The part number code indicates a right-hand version with a straight handle and no actuator tab or ESD symbol option.

 

The Series 71 extractor is suitable for use in card cages and enclosures where reliable PCB retention and extraction are required. The bent leg option is available for use with Lok Tainers in sheet metal applications.
