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, single-
row, carrier-type DIP terminals, wrap terminals, solder-
sleeve terminals, and low-profile DIP terminals.
• Conforms to UL standards (file no. E 103202) and CSA
standards (file no. LR 62678).

XR2T Open-frame Sockets with Seal Tape
•
Equipped with seal tape to prevent flux cleaning liquids from entering the Socket.
•
The same round-pin, 4-point contact structure as the RX2A is used for the contacts.
•
The seal tape is made of transparent polyethyle (adhesive portion) and yellow polypropolyene (non-adhesive portion).
