IC Sockets
XR2
OMRON’s IC Connectors Have Excellent
Reliability and Can Tolerate Momentary
Interruptions in Power.
• Round pins and 4-point (4-finger) contact construction with
contact entry holes that are large for easy insertion.
• IC lead contacts placed high for solid connections.
• A wide product range: open-frame, closed-frame, singlerow, carrier-type DIP terminals, wrap terminals, soldersleeve terminals, and low-profile DIP terminals.
• Conforms to UL standards (file no. E 103202) and CSA
standards (file no. LR 62678).
