Half-pitch Low-profile Stacking Connectors XH4A An Integrated Male/ Female Half-pitch * Stacking Connector with Board Space Adjustable from 5 to 11 mm. ■ Board space can be adjusted from 5 to 11 mm in 1-mm increments. (Surface-mounted Connectors can be adjusted from 5 to 9 mm in 1-mm incre- ments.) ■ The product line includes DIP and SMT Connectors. ■ Integrated male/female Connectors. ■ All models incorporate fastening pins to secure the terminals, thus preventing floating or falling over during soldering. ■ The leaf contact construction resists bending. * Excluding SMT connectors ■ The XH4A conforms to UL standards (file no. E103202). (SMT Connectors not included) ■ Not mated with XH2 and XH3 Half-pitch Connec- tors. RoHS Compliant ■ Terminology • SMT The abbreviation of Surface Mount Technology. Integrated male/female Connectors The male (plug) and female (socket) have the same shape. ■ Ratings and Characteristics Rated current 0.5 A Rated voltage 125 VAC Contact resistance (See note.) 30 mΩ max. (20 mV max., 100 mA max.) Insulation resistance 1,000 MΩ min. (at 500 VDC) Dielectric strength 650 VAC for 1 min (leakage current: 1 mA max.) Total insertion force 1.47 N max. per contact Total removal force 0.15 N min. per contact Insertion durability 50 times Ambient operating temperature −55 to 105°C (with no condensation or icing) Note: The contact resistance depends on which XH4A-@@31 Connectors are mated to each other. ■Materials and Finish Housing PPS (UL94 V-0)/black Locator PBT (UL94 V-0)/black Contacts Mating end Phosphor bronze/nickel base, gold plating Terminal Phosphor bronze/nickel base, gold flash plating Fastening pins Copper alloy/tin plating 1 XH4A Straight DIP Terminals ■ Dimensions (unit: mm) XH4A-@@31 (Straight DIP Terminals) Dimensions Dimensions ABC (mm) No. of contacts Mounting holes Reference 40 32.73 24.13 28.63 (bottom view) 50 39.08 30.48 34.98 40, 60, 80, 100 contacts 60 45.43 36.83 41.33 50 contacts 8058.13 49.53 54.03 100 70.83 62.23 66.73 +0.1 Two, 1.1 dia. 0 +0.1 0.8 dia.
