Half-pitch Low-profile Stacking Connectors
XH4A
An Integrated Male/ Female Half-pitch
Board-to-Board Stacking Connector.
• Board space can be adjusted from 5 to 11 mm in 1-mm increments. (5 to 9 mm in 1-mm increments for SMT versions.)
• The product line includes Through-hole and Surface-mounted
Terminals (SMT) Connectors.
• The leaf contact construction resists bending
• All models incorporate fastening pins to secure the terminals,
thus preventing floating or falling over during soldering.
• The XH4A conforms to EN, IEC, UL (file no. E103202), and
CSA (file no. LR62678). (SMT Connectors not included)

Note: 1. The triangular mark (▼) and contact numbers are not printed on the connectors. Use the raised reference point used to prevent reverse
insertion as a guide when designing boards.
2. On the mating side, the row of terminals on the raised reference point side are called row a, and the row on the other side is called row
b. The numbers are in the order shown.
3. XH4A Half-pitch Connectors are integrated male/female connectors. The contact numbers on row a correspond to the contact numbers
on row b. Be careful when using these connectors because they function slightly differently from separate male and female connectors
(i.e., Plugs and Sockets).

Certain Precautions on Specifications and Use
1. Suitability for Use. Seller shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in
Buyer's application or use of the Product. At Buyer's request, Seller will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not
sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a nonexhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety
equipment, and installations subject to separate industry or government
regulations.
(iii) Use in consumer products or any use in significant quantities.
(iv) Systems, machines and equipment that could present a risk to life or
property. Please know and observe all prohibitions of use applicable to this
product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM
AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT
THE OMRON PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE
INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Seller shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
3. Performance Data. Performance data given in this publication is provided as
a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Seller's test conditions, and the users must
correlate it to actual application requirements. Actual performance is subject to
Seller's Warranty and Limitations of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Seller representative at any time to
confirm actual specifications of purchased Product.
5. Errors and Omissions. The information in this publication has been carefully
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors, or omissions.
6. RoHS Compliance. Where indicated, our products currently comply, to the
best of our knowledge as of the date of this publication, with the requirements
of the European Union's Directive on the Restriction of certain Hazardous
Substances ("RoHS"), although the requirements of RoHS do not take effect
until July 2006. These requirements may be subject to change. Please consult
