resistor in series
Use
24Vdc Voltage
•
•
Use mini contactor or auxiliary relay.

resistor.
Operation
• require prior testing. Use
lter before the Sensor to prevent the internal piston from locking. Not
recommended for industrial water waste.
• require technical
analysis: the Sensor contains magnetic components inside. Use a
magnetic lter before the Sensor to avoid deposition/settling that will
prejudice its operation.
The sensors work in all voltage and current ranges displayed in the table bellow:
Operating Voltage Peak Current
110Vac 20VA 0,2A 0,5A @20ms
220Vac 20VA 0,1A 0,5A @20ms
5Vdc 2,5W 0,5A 1A @20ms
12Vdc 5W 0,5A 1A @20ms
24Vdc 10W 0,5A 1A @20ms
NOT recommended

- Attention to Install
Note: Reed Switches have reached over one million operations in tests with
contactor and K8* snubber lter.
Reed Switches are hermetically sealed contacts
actuated by a magnetic eld.
The life expectancy of a reed switch refers to a
kind of load to be used. Reed Switches of the highest reliability are applied in
our sensors, and their life expectancy can reach above two million operations.
However, when they are switching lamps, inductive or capacitive loads, this
number may decrease.
It is important to consider that the power specied by an electrical load is
often referred to the permanent working state.
For higher power, use an auxiliary relay or contactor as recommended below,
or similar.
This resistor dampens the peak voltage caused by the
capacitance of cables and electronic equipment input.
due to CAPACITANCE, which
can occur depending on the distance and cable used in the connection to the contactor.
