Wiring and connections
Bjong is equipped with IP68 connectors that guarantee protection degree if used in the right way.
All the connectors, arranged on the low side of the Bjong, are
specifically of different sizes or polarity to facilitate the user in their
correct wiring, this precaution prevents the connection of
sensors/peripherals in incorrect inputs.
The functionality of each connector is also highlighted by an
inscription inside the blue label ring.
The sensors purchased with the Bjong are already equipped with a
waterproof IP68 connector to be connected directly to the device. If
the user wants to acquire a signal from its own system, it is necessary
to use the pre-wired connector equipped with free cable lugs.
To connect an external connector:
1. Unscrew the cap;
2. Hold the connector;
3. Place the cable connector in the device connector input;
4. Rotate the connector to insert it slightly;
5. Force the insertion and rotate the ferrule to the limit;
6. Now the connector is correctly fixed and can guarantee IP68 protection.
The incorrect connection of the connectors and the failure to close the plugs of the same,
causes the loss of the IP68 protection degree.
B.M. Tecnologie Industriali is not liable for any damage caused to the system due to incorrect
connection of the connectors or to their damage.
It is possible to request pre-wired connectors with additional cable lugs necessary for your
purpose from the service or from your sales representative.
If the Bjong is equipped with a pressure sensor, there will also be a hole for barometric
compensation (vent). A specific hydrophobic membrane is inserted inside and allows the
instrument to maintain the declared index of protection (IP). See the “Built-in pressure
sensor” section for more details.
