Abstract
To provide a connecting structure for a signal cable capable of securing a sufficient display area concerning a display in a photoelectric switch. A photoelectric switch includes a housing having a substantially rectangular parallelepiped shape. A display 5 is provided on a first surface of the housing and includes a display region. A signal cable 51 connects a control board and the display 5. The display 5 includes a connecting section 70a connected to the signal cable 51. The connecting section 70a is disposed between the display region and the signal cable in the longitudinal direction of the housing. Consequently, a connecting structure for the signal cable 5 capable of securing a sufficient display area concerning the display 5 in the photoelectric switch is provided.
Claims17
A photoelectric switch comprising:
- a housing having a substantially rectangular parallelepiped shape;
- a display unit provided on a first surface of the housing and including a display region;
- a light projecting unit and a light receiving unit provided on a second surface located adjacent to the first surface;
- a receiving unit provided on the first surface and configured to receive operation;
- a display control unit configured to cause the display unit to display, in the display region of the display unit, a threshold adjusted through the receiving unit and a signal value indicating an amount of light received by the light receiving unit;
- a first substrate housed on an inside of the housing, the display control unit being connected to the first substrate;
- and
- a signal cable for connecting the first substrate and the display unit, wherein
- the display unit includes a connecting section connected to the signal cable, and
- the connecting section of the display unit is disposed between the display region and the signal cable in a longitudinal direction of the housing.
A sensor unit comprising:
- a housing having a substantially rectangular parallelepiped shape;
- a display unit provided on a first surface of the housing and including a display region;
- a detecting unit provided on a second surface located adjacent to the first surface and configured to output a detection signal according to a physical quantity detected from a detection target;
- a receiving unit provided on the first surface and configured to receive operation;
- a display control unit configured to cause the display unit to display, in the display region of the display unit, a threshold adjusted through the receiving unit and a signal value indicating the physical quantity detected by the detecting unit;
- a substrate housed on an inside of the housing, the display control unit being connected to the substrate;
- and
- a signal cable for connecting the substrate and the display unit, wherein
- the display unit includes a connecting section connected to the signal cable, and
- the connecting section of the display unit is disposed between the display region and the signal cable in a longitudinal direction of the housing.
