DISTANCE-SETTABLE PHOTOELECTRIC SENSOR

摘要

A light receiver has a shield wall disposed facing a part of a near-side light-receiving face of a light receiving element from an end opposite from a far-side light-receiving face. The shield wall blocks a portion of reflection light from a detection object located at a distance at which the detection object reflects reflection light that causes an amount of light received by the light receiving element to be larger than or equal to a predetermined value.

主权项

1. A distance-settable photoelectric sensor having a light projector that projects light and a light receiver that has a light receiving element extending from a near-side light-receiving face to a far-side light-receiving face and that receives reflection light with respect to the light projected by the light projector, the distance-settable photoelectric sensor detecting presence or absence of a detection object located closer than a set distance based on a light reception result obtained by the light receiver,
wherein the light receiver has a shield wall disposed facing a part of the near-side light-receiving face of the light receiving element from an end opposite from the far-side light-receiving face, the shield wall blocking a portion of reflection light from the detection object located at a distance at which the detection object reflects reflection light that causes an amount of light received by the light receiving element to be larger than or equal to a predetermined value.
