■Plug-in Models

Specifications

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-GP-

N8HY 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 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.

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
