摘要： To provide a multi-optical axis photoelectric sensor and a multi-optical axis photoelectric sensor system, which enable function setting by an extremely simple operation, and further make it unnecessary to increase the size of a housing or to separately prepare a PC or a function setting tool. The multi-optical axis photoelectric sensor has: a columnar housing, from one end of which in the longitudinal direction an electric cord is pulled out, and at the other end of which in the longitudinal direction a plug-in type socket is provided, and a plug piece detachably attachable to the socket of the columnar housing. Particular information to serve as a function determining element on the columnar housing side is incorporated in the plug piece in a manner referenceable from a processing circuit on the columnar housing side via the socket. Further, the processing circuit on the columnar housing side is set so as to determine a function based upon particular information in the plug piece referenced via the socket.

摘要： The present invention provides a multiple-optical-axis photoelectric sensor in which an error in detection of an object caused by disturbance light is prevented easily and efficiently by adjusting a light projection/reception cycle in accordance with a state where mutual interference is recognized. In the invention, by detecting a range in which mutual interference occurs, that is, the position in which disturbance light is detected, which is either a first-half period or a latter-half period of a whole light projecting/receiving operation period, whether the phase is advanced or delayed is determined. For a period according to the position of the optical axis in which incidence of disturbance light is recognized or the number of optical axes in which incidence of disturbance light is recognized continuously, a scheduled next sync timing is changed.

摘要： A photoelectric switch emits pulsed detection light and outputs a light detection signal as reflected light is received. For generating an on-off judgment output for switching on and off, the level of the light detection signal is shifted towards a specified level during a specified light receiving period by an amount corresponding to the difference between the specified and the level of the light detection signal at a time immediately before the pulsed detection light is expected to arrive. On the basis of thus level-shifted signal, it is determined whether at least one of the conditions for generating the on-off judgment output is satisfied. The on-off judgment output is generated at least on the condition that the levels of the light detection signal at specified timings are in a specified size relationship. According to another embodiment, pulsed detection light is emitted at least three times per cycle of noise from a fluorescent lamp and comparisons are made between a specified level and the level of the light detection signal whenever a peak of the pulsed detection light is expected to arrive, and the on-off judgment output is generated according to the majority of the results of comparisons made during a period of light emission.
