The low-voltage plugs on SN transmitters can be opened up. This simplifies fitting and also means that the supply voltage and output signal can be measured directly from the opened plug.
As-delivered condition:
The transmitters are fully assembled in the factory (sensor + evaluation module + cover) and set to the nominal range. Additional modules and external modules are supplied separately.
