摘要：
The present invention relates to a photoelectronic sensor which collectively adjusts light emission intensity of plural light emitting elements and light reception sensitivity of plural light receiving elements automatically or manually.In order to collectively adjust light emission intensity of plural light emitting elements and light reception sensitivity of single light receiving elements automatically, a photoelectronic sensor of the present invention is configured such that constant current light emission signal are applied to the light emitting elements, a light amount of environment is measured by the light receiving elements and stored, a reflection light amount from a body to be measured is stored, signal intensities indicating the respective light amounts are calculated, optimal thresholds of light emission intensity and light reception sensitivity are provided automatically or manually, so that setting of sensor sensitivity is performed.
