Note: 1. The length when using completely insulated, 600-V, 3-conductor (0.75 mm2) cabtire cables. Usable cable lengths will become shorter as
the cable diameter or number of conductors becomes larger. For details, refer to Safety Precautions for Floatless Level Controllers.
2. The insulation resistance and dielectric strength indicate values between power terminals and Electrode terminals, between power
terminals and contact terminals, and between Electrode terminals and contact terminals. For details, refer to Safety Precautions for
Floatless Level Controllers.
3. Possible to use with 15 kΩ or less, however, this may cause reset failure.
4. 61F-GP-NH High-sensitivity Controller uses advanced operation.
When the power supply voltage is applied, if there are some liquids between the electrodes (ground and operation electrodes), the inter-
nal relay will not operate.
When the power supply voltage is applied, if there are no liquids between the electrodes (ground and operation electrodes), the internal
relay will operate.
If the advanced operation does not satisfy applications, consider using 61F-N8HY controller which uses sequential operation.

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

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.
