IC Sockets XR2 OMRON’s IC Connectors Have Excellent Reliability and Can Tolerate Momentary Interruptions in Power. Ideal for Highspeed Data Processing. ■ Round pins and 4-point (4-finger) contact construction ensure long life and excellent shock and vibration durability. ■ 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, single-row, carrier-type DIP terminals, wrap terminals, solder-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). RoHS Compliant ■ Construction ■ Contact Dimensions DIP Terminals Inner clip Base Low-profile DIP Terminals Wrap Terminals 1.83 dia. 1.83 dia. 1.83 dia.
