IC Sockets XR2 OMRONs 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. See theStandards certification / conformity lis for information on conformity to certification standards.
