Abstract: Provided is a displacement sensor having a modular structure that allows further downsizing. A housing of a head is made up of a main housing and a lid member, both of which are precision molded products made of a metal material. A first holder to which a light projector is bonded and a second holder to which a light receiver is bonded are individually positioned on and bonded to the lid member. This work is performed by a mounting device. Optical components such as a light projecting lens are also bonded to the lid member, and the lid member modularized by incorporating such optical components is assembled and welded to the main housing.

Abstract: To make a display in a photoelectric switch easy to see for a user. A photoelectric switch includes a housing having a substantially rectangular parallelepiped shape. A display is attached to a first surface of the outer surface of the housing. A control board is housed on the inside of the housing. A controller is mounted on the control board. The first surface includes a hole-like or cutout-like opening section for allowing a signal cable to pass from the outside to the inside of the housing. The signal cable electrically connects the control board disposed on the inside of the housing and the display disposed on the outside of the housing. A cover member includes a window section for exposing a display region of the display and covers a non-display region of the display. The cover member is provided outside the housing.

Abstract: Provided is a safety scanner capable of obtaining uniform optical performance for a view angle of 180° or more. The safety scanner includes an optical rotator that emits detection light from a light source to a detection area and causes the detection light to perform scanning in a circumferential direction, a light receiving element that receives reflected light from an object within the detection area through the optical rotator, a casing that houses the light receiving element. The casing includes a canopy part, a bottom part facing the canopy part, and a coupling part that couples a rear end of the canopy part to a rear end of the bottom part. The protective cover includes a window formed in a circular arc shape, corresponding to an optical path of the detection light and the reflected light, having a central angle larger than 180° with respect to the rotation axis.

Abstract: Provided is an optical displacement sensor that allows a housing serving as a head to be downsized. A relay cable extending from the head is integrated with a body. The head is primarily responsible for projecting and receiving light to and from a to-be-detected object, while the body is made up of a power supply circuit, a display, and an operation part. The head includes a green laser light source and emits the green laser light to form a spot on a surface of the to-be-detected object.

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.
