IC Sockets XR2 OMRON’s IC Connectors Have Excellent Reliability and Can Tolerate Momentary Interruptions in Power. Ideal for High- speed Data Processing. ■Round pins and 4-point (4-finger) contact construction ensure long life and excellent shock and vibration dura- bility. ■Contact entry holes are large for easy insertion. ■IC lead contacts placed high for solid connections. ■No flux rise. ■A wide product range: open-frame, closed-frame, sin- gle-row, carrier-type DIP terminals, wrap terminals, sol- der-sleeve terminals, and low-profile DIP terminals. ■A new tin-plated product series offers more choice when it comes to selecting the optimum IC Socket for an application. ■Conform to UL standards (file no. E 103202) and CSA standards (file no. LR 62678). ■Construction■Contact Dimensions DIP Terminals Low-profile DIP Solder-sleeve Wrap Inner clip Terminals Terminals Terminals Base 1.83 dia. 1.83 dia. 1.83 dia. 1.83 dia.
