The disclosure provides a photoelectric sensor that provides useful information to set measurement conditions. The photoelectric sensor includes a light emitting unit having a light emitting element configured to emit detection light toward a detection area, a light receiving unit having a light receiving element configured to receive the detection light from the detection area and to obtain a detection value corresponding to the amount of light received, and a display unit configured to display information about the detection value in the light receiving unit. When the detection value varies across a predetermined threshold, the display unit displays a transit time that is the time from when the detection value crosses the predetermined threshold until when it crosses the predetermined threshold again, and a variation amount of the detection value in the variation.

This application claims priority to Japanese Patent Application No. 2012-233404 filed on Oct. 23, 2012, the entire contents of which are incorporated by reference herein.
Disclosed herein is a photoelectric sensor, and more particularly, a photoelectric sensor with a display.
Photoelectric sensors are widely used to detect the presence or absence of an object moving, for example, in a factory production line. Conventionally, various techniques have been proposed for such photoelectric sensors.
FIG. 1 is a view showing the appearance of an optical fiber type photoelectric sensor that is an embodiment of a photoelectric sensor;
FIG. 2 is a perspective view showing the body in a state where the cover is opened;
FIG. 3 is a diagram illustrating the upper surface of the photoelectric sensor when viewed from the front;
Embodiments of the photoelectric sensor will now be described with reference to the drawings. The same components are denoted by the same reference numerals in the drawings, and detailed descriptions are not repeated.
A. Appearance of Photoelectric Sensor
FIGS. 1 and 2 are diagrams illustrating the appearance of an optical fiber type photoelectric sensor, which is an embodiment of a photoelectric sensor.
