Half-pitch Fine-fit and Stacking Connectors
XH3
Half-pitch Fine-fit Connectors Achieve
High-density Mounting without
Soldering
■ Solderless connection eliminates soldering and
washing processes.
■ Multi-level stacking conserves board space.
■ Requires half the space of conventional DIN con-
nectors (OMRON’s XC5B).
■ At a stacking height of 16.8 mm, the XH3 can be
stacked together with DIN connectors.
■ Mates with conventional XH3-series Half-pitch
Connectors.
(See the Mating Diagram on page 4.)
■ Allows press fitting using commercial tools.
RoHS Compliant

■Ratings and Characteristics
• Fine-fit
Refers to a press-fit connection using Omron's own ter-
minal shape.
Rated current
Rated voltage
0.5 A
125 VAC
• Solderless connection
Contact resistance (See note.) 40 mΩ max. (at 20 mV, 100 mA max.)
Refers to a solderless electric connection of a connec-
tor, electric cable and printed circuit board. It involves
crimping, IDC pressing, press-fitting (fine-fit), etc. A
solderless connection generally refers to a press-fit con-
nection.

• Stacking
Ambient operating temperature Operating: −55 to 105°C (with no icing)
Connects the printed-wiring boards parallel to each other.
The distance between the boards here is called "stack-
ing height".
Note: The contact resistance is for the XH3B-013P-D32 com-
bined with the XH3B-013P-D5F (with the XH3B-013P-
D32 terminal used as the plug).
