Patent ID: 8445833

Claim:
An optoelectronic sensor, comprising a first strip ( 8 ) having transmitter elements (L 1 -Ln) and/or receiver elements (E 1 -En), a second strip ( 10 ) having transmitter elements (L 1 -Ln) and/or receiver elements (E 1 -En), wherein the transmitter elements (L 1 -Ln) of one strip ( 8 , 10 ) form transmitter/receiver pairs with receiver elements (E 1 -En) of the other strip ( 10 , 8 ) for the formation of a protective field ( 14 ), and an evaluation unit ( 22 ) for the evaluation of the received light of the receiver elements (E 1 -En), wherein a light beam ( 12 ) between the transmitter elements (L 1 -Ln) and receiver elements (E 1 -En) counts as interrupted when received light falls below a first lower switching threshold (S 1 ) and as not interrupted when a first lower switching threshold (S 1 ) is exceeded and wherein an object detection signal can be transmitted when at least one light beam ( 12 ) is interrupted, wherein for the evaluation of the received light of at least one receiver element (E 1 -En), a second upper switching threshold (S 2 ) is provided in the evaluation unit ( 22 ) the value of which lies above the value of the first lower switching threshold (S 2 ), with a signal to indicate bypass light being given when the value of the received light lies above the second upper threshold (S 2 ).
