XR2IC Sockets
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).
■Terminology
zCarrier type
Carrier type refers to products where only terminals are
mounted by removing the carrier after mounting on the
board.
zSolder sleeve type
Solder sleeve type refers to products with a board mount-
ing height of 0.8 mm that can be used in locations with
height restrictions.
