FOR BOARD-TO-BOARD CONNECTION 240 SERIES (LOW-PROFILE STACKING) ■ 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 × 1.905 mm) (0.100 in. × 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 Operating temperature range –55°C to +105°C Insulator Current rating DC 1 A Conductor Voltage rating AC 250 V Contact resistance 35 mΩ max.
