Document Type and Number:
Japanese Patent JP7085885
Kind Code:
B2
Abstract:
A photoelectric sensor provided by the invention can prevent the optical axis from deviating. This photoelectric sensor is provided with a light projection unit (2) having a light-emitting element (21) that emits infrared light, and a light projection lens (22) that projects the infrared light emitted by the light-emitting element (21) to the outside; and a light projection unit (3) having a light-emitting element (31) which is arranged side by side with the light-emitting element (21) and emits visible light, and a light projection lens (32) which projects the visible light emitted by the light-emitting element (31) to the outside, the light projection unit (3) projecting the visible light in the same direction as the infrared light projected by the light projection unit (2).
