G7SA
CSM_G7SA_DS_E_10_3
Compact, Slim Relays Conforming to
EN Standards
• Relays with forcibly guided contacts
(EN50205 Class A, certified by VDE).
• Supports the CE marking of machinery (Machinery
Directive).
• Helps avoid hazardous machine status when used as part of
an interlocking circuit.
• Four-pole and six-pole Relays are available.
• The Relay’s terminal arrangement simplifies PWB pattern
design.
• Reinforced insulation between inputs and outputs.
Reinforced insulation between some poles of
different polarity.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read the “Safety Precautions” on page 6 and the
“Precautions for All Relays with Forcibly Guided Contacts”.

Note: 1. The above values are initial values.
2. Performance characteristics are based on coil
temparature of 23°C.
*1. The contact resistance was measured with 1 A at 5
VDC using the voltage-drop method.
*2. These times were measured at the rated voltage and
an ambient temperature of 23°C. Contact bounce
time is not included.
*3. The response time is the time it takes for the normally
open contacts to open after the coil voltage is turned
OFF. Contact bounce time is
included. Measurement conditions: Rated voltage
operation, Ambient temperature: 23°C
*4. The insulation resistance was measured with a 500VDC megohmmeter at the same locations as the
dielectric strength was measured.
*5. Pole 3 refers to terminals 31-32 or 33-34, pole 4
refers to terminals 43-44, pole 5 refers to terminals
53-54, and pole 6 refers to terminals 63-64.
*6. When using a P7SA Socket, the dielectric strength
between coil contacts/different poles is 2,500 VAC,
50/60 Hz for 1 min.
*7. The durability is for an ambient temperature of 15 to
35°C and an ambient humidity of 25% to 75%. For
the durability performance to the load, refer to the
Durability Curve.
*8. AC15: cosφ = 0.3, DC13: L/R = 48-ms.
*9. The failure rate is based on an operating frequency
of 300 operations/min.
*10.12 to 48 VDC:
When operating between 70 and 85°C, reduce the
rated carry current of 6 A by 0.1 A for each degree
above 70°C.
110 VDC:
When operating between 40 and 60°C, reduce the
rated carry current of 6 A by 0.27 A for each degree
above 40°C.

Safety Precautions
Be sure to read the precautions for “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided
Contacts” in the website at:http://www.ia.omron.com/.
Precautions for Correct Use
Supplementary comments on what to do or avoid doing,
to prevent failure to operate, malfunction or undesirable
effect on product performance.
Wiring
• Use one of the following wires to connect to the
P7SA-10F/10F-ND/14F/14F-ND.
Stranded wire: 0.75 to 1.5 mm2
Solid wire:
1.0 to 1.5 mm2
• Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to a
torque of 0.78 to 0.98 N·m.
• Wire the terminals correctly with no mistakes in coil polarity,
otherwise the G7SA will not operate.
• If you use the [email protected], the release time and the response
time of the G7SA will be longer because the [email protected] has a
built-in diode to absorb coil surge. Confirm operation under actual
conditions before you use the [email protected]
Cleaning
The G7SA is not of enclosed construction. Therefore, do not wash the
G7SA with water or detergent.
Mounting
The G7S can be installed in any direction.
Direction for Inserting and Removing the Relay
When you insert the Relay into the Socket or remove the Relay from
the Socket, keep the Relay perpendicular to the surface of the Socket.
If you hold the Relay at an angle when you insert or remove it, the
Relay pins may be bent and Socket contact failure may occur.

Limitation on Liability; Etc.
OMRON COMPANIES SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,
LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY WAY CONNECTED WITH THE PRODUCTS,
WHETHER SUCH CLAIM IS BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.
Further, in no event shall liability of Omron Companies exceed the individual price of the Product on which liability is asserted.
Suitability of Use.
Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the
combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron 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.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY OR IN LARGE
QUANTITIES WITHOUT ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS,
AND THAT THE OMRON PRODUCT(S) IS PROPERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
Programmable Products.
Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence
thereof.
Performance Data.
Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining
suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate
it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
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 Omron’s representative at
any time to confirm actual specifications of purchased Product.
Errors and Omissions.
Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is
assumed for clerical, typographical or proofreading errors or omissions.
