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

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

XR2C Single-row Sockets
• The contact has a round-pin 4-point contact structure, which is the same as the XR2A series.
• The single-row type allows you set the pitch between lines freely.
• Components can easily be divided into a desired number of pins.
