Abstract

The photoelectric sensor includes a light projecting part emitting light, a light receiving part receiving light, a housing housing the light projecting part and the light receiving part, a setting part receiving an input operation from outside to set a threshold value, and an adjustment part receiving an input operation from outside to finely adjust the set threshold value. The housing includes a front surface having a light projecting/receiving surface allowing light from the light projecting part and light to the light receiving part to pass, a rear surface located on a side opposite to the front surface, a top surface adjacent to the front surface and extending in a direction orthogonal to the front surface and the rear surface, and an inclined surface inclined with respect to and connecting the top surface and the rear surface. The adjustment part is provided on the inclined surface.

First claim

What is claimed is:

1. 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, and an adjustment part that receives an input operation from outside to finely adjust the threshold value that has been set, 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 adjustment part is provided on the inclined surface.

2. The photoelectric sensor according to claim 1 , wherein the inclined surface is smaller than the second surface and the third surface.

3. The photoelectric sensor according to claim 2 , wherein the setting part is provided on the second surface or the third surface.

4. The photoelectric sensor according to claim 3 , wherein the second surface is provided with a display part for displaying the threshold value.

5. The photoelectric sensor according to claim 2 , wherein the second surface is provided with a display part for displaying the threshold value.

6. The photoelectric sensor according to claim 1 , wherein the second surface is provided with a display part for displaying the threshold value.

7. 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, and an adjustment part that receives an input operation from outside to finely adjust the threshold value that has been set, wherein
the housing has a substantially rectangular parallelepiped shape, and
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
a chamfered region formed by chamfering a corner of the substantially rectangular parallelepiped shape so as to connect the third surface and the second surface, wherein
the adjustment part is provided in the chamfered region.
