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)(Excluding
XR2P).
* Excluding XR2P
RoHS Compliant

■ Precautions
Correct Use
Soldering
• When soldering, make sure that the outer
sleeve of the IC Socket does not stick out
of the circuit board through-holes.
• Make sure that no flux enters the IC
Socket from the top.
Removing ICs
• Use the XY2C-0101 or XY2C-0103 IC
Removal Tool to remove ICs.
• Do not use a screwdriver to remove the
IC. It may damage the circuit board.
• Do not use a testing rod or check pin to
check contacts or circuits. This may damage the inner clips or plating and may
lead to improper contact.
• Four-point contact construction is used for
plated products to make them more tolerant of momentary power interruptions.
We recommend using gold-plated contacts in areas subject to vibration and
shock.
Automated Soldering
Conditions (Jet Flow)
Applicable IC Lead
Dimensions
1. Use leads that are within the range
shown here. For details, refer to page 2.
Use an IC with leads longer than 3 mm.
If the leads are too long, the IC will not
sit flush on the board.
2. Use an IC with tapered leads for easy
insertion, a minimum amount of bending, and minimum damage to the leads.
