Floatless Level Switch (Ultra High-sensitivity Type)
61F-UHS/-HSL
CSM_61F-UHS_-HSL_DS_E_2_3
Ideal for Detecting Ice, Pure Water, or
Humidity
• Applicable for detecting ice, pure water steam, humidity, or other
substances that conduct electricity poorly.
• Two types of model available: Ultra high-sensitivity and variable
ultra high-sensitivity.

Note: 1.
Use 61F-UHS for detecting water leakage with high specific resistance. Connect a sensor cable between terminals 1 and 7.
2.
Two Electrodes can be connected to the 61F-HSL. Use them for an alarm, not for creating a self-holding circuit.
3.
The length when using completely-insulated, 600-V, 3-conductor (0.75 mm
2
) cabtire cables. Usable cable lengths will become shorter as
the cable diameter or number of conductors becomes larger. For more details, refer to
Safety Precautions for Floatless Level Controllers.
4.
It is recommended that the cable length be kept as short as possible since the Electrode circuit current is at DC micro-current level. More-
over, the Electrodes will corrode rapidly if the current is allowed to constantly flow between the Electrodes.
Be careful with the electrode polarity and grounding when wiring.
