Abstract

Optoelektronische Fühlerleiste bestehend aus einer optoelektronischen Empfangseinrichtung (2) und einer optoelektronischen Sendeeinrichtung (1). Das von der Sendeeinrichtung (1) ausgestrahlte Licht füllt den zu überwachenden Raum mit diffuser Strahlung aus. Die Empfangseinrichtung (2) erhält auch bei Abdeckung der direkten Strahlung, durch ein Hindernis (4) zwischen Sender und Empfänger, noch genügend Signal aus dem diffusen Lichtfeld. Wenn jedoch ein Hindernis (5) den Empfangssensor weitgehend abdeckt, wird ein Ausgangssignal zur Steuerung einer entsprechenden externen Einrichtung abgegeben. Optoelectronic sensor strip consisting of an optoelectronic Receiving device (2) and an optoelectronic transmitting device (1). The light emitted by the transmitter (1) fills the monitoring room with diffuse radiation. The receiving device (2) receives even if direct radiation is covered by an obstacle (4) between transmitter and receiver, still enough signal from the diffuse Light field. However, if there is an obstacle (5) the receiving sensor largely covers an output signal to control a corresponding given to an external institution.
