YOU MUST CHECK BEFORE INSTALLATION
For installations according to this guide:
02 (two) years warranty. Incorrect installation cancels the warranty.
All Sensors have been tested and approved during the manufacture process.

• Liquids with solid particles and/or fouling require prior
testing. Use lter before the Sensor to prevent the internal piston
from locking. Not recommended for industrial water waste.
• Liquids with ferrous and/or magnetic particles 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.

• AUXILIARY CONTACTOR (mini contactor) mind the distance:
• SOLENOID VALVE or POWER CONTACTOR:
Use mini contactor or auxiliary relay.
• ELECTRONIC EQUIPMENT:
› Interface relay/relay coupler: Use 4K7 10W resistor.
› Timing relay and frequency inverter: Use 220R 5W*resistor.

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.
Switching Power
It is important to consider that the power specied 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.
Note: Reed Switches have reached over one million operations in
tests with contactor and K8* snubber lter.
PROTECTION PROCEDURES BELOW DESCRIBED CAN

K8* Filter mounted in parallel
with the coil of an AC contactor,
increases the contact life.
KD* Filter mounted in parallel
with the coil of a DC relay,
increases the contact life.
Important: For distances greater than 40m, use 24Vdc voltage.
•Timing relay
•Frequency inverter
•Etc.
Important: For installation with relay coupler, use 4K7 10W resistor.
• Switching inductive loads
? Risk of failure (welding of the Reed Switch Contact) due to CAPACITANCE, which
can occur depending on the distance and cable used in the connection to the contactor.
• Connecting the sensor to a contactor in long distances, use resistor:
This resistor dampens the peak voltage caused by the
capacitance of cables and electronic equipment input.
• Connecting the sensor to an electronic equipment:

1. Open the plug, remove the spring and clean using a brush
if there is encrustation;
2. Mount the sensor again as illustrated beside;
3. Test the electrical contact using an ohmmeter, moving the
magnetic piston.
