CALMARK CORPORATION

<p>The 71-2-L is a PCB card ejector from Calmark Corporation, designed for use with 1/16-inch (1.6mm) thick printed circuit boards. It is constructed from 6061-T6 aluminum alloy per QQ-A-250/8, providing a lightweight yet durable solution for board extraction. The ejector offers a mechanical advantage of 4.5:1 and a minimum extraction travel of 11.4mm, ensuring easy removal of PCBs from card guides or enclosures.</p><p>&nbsp;</p><p>Two extractors are recommended per board, typically one left-hand (L) and one right-hand (R) version. The part number 71-2-L indicates a left-hand model with a straight handle and no actuator tab or ESD symbol. The finish is customer specified, allowing customization for specific applications. The ejector weighs approximately 1.42 grams.</p><p>&nbsp;</p><p>This ejector is part of the Series 71 family and is commonly used in electronic enclosures and rack systems where reliable PCB extraction is required. The design includes a pin for board module assembly.</p>

<p>The 71-3-R is a right-hand PCB card ejector from the CALMARK Series 71 family, designed for use with 3/32" (2.4mm) thick printed circuit boards. It is fabricated from 6061-T6 aluminum alloy per QQ-A-250/8, providing a lightweight yet durable extraction solution. The ejector has an overall length of 38.1mm and width of 25.4mm, with a weight of 1.42g. It offers a minimum extraction travel of 11.4mm, achieved through a 4.5:1 mechanical advantage. Two extractors (one left and one right) are recommended per board for balanced operation. The ejector is suitable for use in card cages, enclosures, and rack systems requiring reliable PCB insertion and extraction.</p>
