光电传感器

Abstract

The utility model relates to a photoelectric sensor. The photoelectric sensor comprises a first infrared ray transmitting diode D1, a second infrared ray transmitting diode D2, a third infrared ray transmitting diode D3, a fourth infrared ray transmitting diode D4, a first infrared ray receiving diode D5, a second infrared ray receiving diode D6, a third infrared ray receiving diode D7, a fourth infrared ray receiving diode D8, current-limiting resistors R1, R2, R3, R4, pull-up resistors R5, R6, R7, R8, a socket P1 and a logic chip U1. The photoelectric sensor provided by the utility model is high in reliability, not only can detect a target object which is small in size, variable in shape and even be fixed in position relative to the sensor, but also is small in detection blind area.
