Note: 1. The relay in the 61F-G1H/-G2H/-IPH de-energizes when there is water present across the Electrodes, whereas the relay in the 61F-GPN8HY energizes when there is water present across the Electrodes.
2. Models are available for 2 km and 4 km.
3. 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.
4. 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.
5. Possible to use with 15 kΩ or less, however, this may cause reset failure.
6. High-sensitivity Controllers use advanced operation.
When the power supply voltage is applied, if there are some liquids between the electrodes (ground and operation electrodes), the internal 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.

• The pump starts when the water level in the tank drops below
E2 and stops when the water level reaches E1.
• When the level of water supply source drops below E2', the
pump stops. Pumping idling is prevented and the alarm
sounds.
• The pump stops when the water level reaches E1 and starts
when the water level in the tank drops below E2.
• If the water level drops below E4 for any reason, the pump
stops and the alarm sounds.

machine, system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
• Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
• Nuclear 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.
• Systems, machines, and equipment that could present a risk to life or property.

OMRON shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
Disclaimers
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 model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog 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 users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
