oO FUJITSU TAKAMISAWA FUJITSU Gincoronenralot FOR BOARD-TO-BOARD CONNECTION 240 SERIES (LOW-PROFILE STACKING) m@ FEATURES The connectors can connect boards in parallel (stacking) at intervals of 8 mm (0.31 in.) to 14 mm (0.55 in.) for various applications. Connectors with ten different numbers of contacts are available for various purposes: 20 to 100 in steps of ten and 120. Connectors are surface mount compatible. 1.27 mm (0.050 in.) pitch contact arrangement in two rows enables high-density mounting. Tails are spaced in a four-row staggered arrangement (2.54 mm x 1.905 mm) (0.100 in. x 0.075 in.) for easy patterning on PC boards. Bellows contacts ensure stable contact preventing pins from bending. The bellows contacts also have excellent stability with repeated insertion and extraction. @ SPECIFICATIONS @ MATERIALS Item Specifications Item Materials Operating temperature range 55C to +105C Insulator Polyamide resin (94V-0) Current rating DC1A Conductor Copper alloy Voltage rating AC 250 V Plating Contact Gold plating (PAGOS) Contact resistance 35 mQ max.
