    摘要: An optoelectronic sensor, comprising a first strip having transmitter elements and/or receiver elements, a second strip having transmitter elements and/or receiver elements, wherein the transmitter elements of one strip form transmitter/receiver pairs with receiver elements of the other strip for the formation of a protective field, and an evaluation unit for the evaluation of the received light of the receiver elements, wherein a light beam between the transmitter elements and receiver elements counts as interrupted when received light falls below a first lower switching threshold and as not interrupted when a first lower switching threshold is exceeded and wherein an object detection signal can be transmitted when at least one light beam is interrupted, characterized in that for the evaluation of the received light of at least one receiver element a second upper switching threshold is provided in the evaluation unit the value of which lies above the value of the first lower switching threshold, with a signal to indicate bypass light being given when the value of the received light lies above the second upper threshold.

    摘要: A sensor system includes at least one safety sensor unit for monitoring a safety relevant zone of a plant. The sensor system also includes a display unit connected to the sensory unit or integrated into it. The sensor system outputs a safety switch signal on an intrusion of an unpermitted object into the monitored, safety relevant zone and the safety sensor unit has an input interface for receiving a further safety switch signal. The input interface can be configured such that, on the one hand, it can receive the further safety switch signal and, on the other hand, can also receive external, non-safety relevant signals of an external device. The display unit is designed to display internal state data of the sensor system and information resulting from the external non-safety relevant signals.

    摘要: An optoelectronic sensor (10), in particular a light barrier having a light transmitter (14) for the transmission of a light beam (18) and a light receiver (26) arranged facing the light transmitter (14) at an alignment angle to transform the received light beam (18) into an electrical received signal is provided, wherein the transmission power of the light transmitter (14) and/or the reception sensitivity of the light receiver (26) is/are set, such that the received signal has an intensity distribution varying in accordance with the alignment angle and wherein an evaluation unit (28) of the sensor (10) is configured to determine by means of the received signal whether the light beam (18) is interrupted or not. In this respect the intensity distribution is stored in a memory (28a) of the sensor (10) and in that the evaluation unit (28) is configured to determine, with reference to the measured intensity of the received signal from a measured intensity distribution, a lower threshold (38) and an upper threshold (40) whose separation corresponds to an accepted angular range.
