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).

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 dam-
age the inner clips or plating and may
lead to improper contact.
•Four-point contact construction is used for
plated products to make them more toler-
ant of momentary power interruptions.
We recommend using gold-plated con-
tacts in areas subject to vibration and
shock.
Automated Soldering
Conditions (Jet Flow)
1. Soldering temperature: 250±5°C
2. Continuous soldering time: Within 5 s
Applicable IC Lead
Dimensions
1. Use leads that are within the range
shown here. For details, refer to the first
page of this datasheet. 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 bend-
ing, and minimum damage to the leads.
