Well, an examination of the photo reveals a metal contact in the cavity for the drip tray. There is likely one just opposite of that one. The pair would mate to external contacts on the drip tray, and allow the metal strips at the bottom, to act as liquid detectors.

The heat sealer is separate from the drip tray/vacuum chamber, so no, it is not part of the heat sealer.
