An aspect of the present invention allows for determining a cause of abnormality in output of a light-receiving element among light-receiving elements in a multiple optical-axis photoelectric sensor. A multiple optical-axis photoelectric sensor () determines that electrical noise occurs, in a case where abnormality in output occurs in both of adjacent light-receivable periods (Ts) in one light-receiving cycle (Tc).

Determination device, multiple optical-axis photoelectric sensor, determination device control method, information processing program, and recording medium

The present invention allows a user to easily grasp which light receiving section is in what light reception state. The multiple-optical-axis photoelectric sensor () includes: a plurality of light receiving sections (); a display section () which is provided in the vicinity of a corresponding light receiving section among the plurality of light receiving sections (), the display section () displaying a light reception state of the corresponding light receiving section; and a display control section () which causes the display section () and the display section () to simultaneously display the light reception state.

Multiple-optical axis photoelectric sensor

A sensor output IC has a switching element that turns on and off between output terminals based on a detection signal from a sensor, and a temperature-limiting circuit that maintains the switching element in an off state when a temperature at the sensor output IC becomes a predetermined value or more.
