Abstract
Description
Aus dem Stand der Technik sind optische Sensoren mit seitlich geöffnetem Gehäuse bekannt, die durch einen Deckel in Ultraschallschweißtechnik verschlossen werden.Out In the prior art are optical sensors with laterally open casing known, which closed by a lid in ultrasonic welding technology become.
Nachteile:Disadvantage:
- – separate Fixierung und Dichtung des Steckers erforderlich,- separate Fixation and sealing of the connector required,
- – Kontaktierung des Steckers in den beengten Verhältnissen im Gehäuse, zum Beispiel durch Anlöten,- contacting of the plug in the cramped conditions in the housing, to Example by soldering,
- – durch das Einpressen des Steckers ergibt sich eine zusätzliche Fügerichtung- by the pressing of the plug results in an additional joining direction
- – separate Fixierung des Kabels durch ein an das Kabel angespritztes Teil erforderlich,- separate Fixation of the cable by a molded part to the cable required,
- – separater Lichtleiter mit Dichtelement für die optische Statusmeldung erforderlich,- separate Optical fiber with sealing element for the optical status message is required
- – Unsicherheit bezüglich der Dichtung bei großen und unregelmäßig berandeten Deckeln.- uncertainty in terms of the seal at large and irregularly edged Lids.
