XR2B Closed-frame Sockets

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)(Excluding XR2P).
RoHS Compliant
