Photoelectric sensor

A photoelectric sensor, comprising a light projecting part that emits light, a light receiving part that receives light, a housing that houses the light projecting part and the light receiving part, a setting part that receives an input operation from outside to set a threshold value, an adjustment part that receives an input operation from outside to finely adjust the threshold value that has been set, and an indicator that displays a detection result of an object being detected, wherein

• the housing comprises:
• a first surface having a light projecting/receiving surface allowing light from the light projecting part and light to the light receiving part to pass;
• a second surface located on a side opposite to the first surface;
• a third surface adjacent to the first surface and extending in a direction orthogonal to the first surface and the second surface;
• and
• an inclined surface inclined with respect to the third surface and the second surface and connecting the third surface and the second surface, wherein
• the setting part and the indicator are provided on the third surface in order from the side of the inclined surface, and
• the adjustment part is provided on the inclined surface, and
• a distance between the setting part and the adjustment part is larger than a distance between the setting part and the indicator.
