Sensor
To guarantee the water-tightness of the
connections of the wires in the module hose,
using watertight terminals is recommended.
The connection through these terminals must
be made without stripping the cable wires.
The 3M Scotchlok series (www.3m.com);
ES Caps from TYCO Electronics (www.
tycoelectronics.com); or Cellpack resin splice
and derivation kits (www.cellpackiberica.
com) can be used as connection elements.

It is recommended that loose cables also be connected with an excess of 3M of
connector to avoid possible short circuits or from them getting wet.
