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: A worker is prevented from being hindered. A safety switch includes a switch body including an electromagnet and an actuator attracted to the electromagnet. The switch body includes a drive control unit and a safety control unit which control the safety switch, and the drive control unit and the safety control unit are surrounded by a housing. The housing is arranged on a back surface side of the electromagnet of the switch body, and the housing forms an accommodating portion that accommodates the drive control unit and the safety control unit.

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.
