Abstract: To realize both toughness and size reduction of a safety switch. A safety switch is a safety switch into and from which a bolt of an actuator is inserted and pulled out. The safety switch includes a casing having a shape elongated along a first direction, a metal head having a receiving space for receiving the bolt of the actuator and provided on a first end side of the casing in the first direction, a detector for detecting a first state in which the bolt is received in the receiving space, a lock mechanism, a switching device and a first attachment portion provided in the head and having a first attachment hole into which a first attachment member is inserted.

Abstract: There is provided a photoelectric switch capable of reducing a size of a whole device while suppressing light amount irregularity and color irregularity of detected light. The photoelectric switch includes: a surface mount LED, configured to generate a light containing a plurality of color components with different hues; an optical shield disposed between the surface mount LED and a light projecting lens to shield the light around an optical opening passing the light from the surface mount LED to the light projecting lens; a light receiving element configured to selectively receive the light to generate a plurality of light reception signals; a controller configured to control a light projecting amount of the surface mount LED based on the light reception signal.

Abstract: To monitor individual safety components or to supply individual operation instructions to corresponding safety components. A connector includes a component-side terminal group used for connection to a corresponding safety component, a downstream-side terminal group used for connection to the downstream side and an upstream-side terminal group used for connection to the upstream side. The downstream-side terminal group includes a downstream-side main information terminal connected to the component-side main information terminal and a downstream-side other terminal different from the downstream-side main information terminal. The upstream-side terminal group includes an upstream-side information terminal capable of being connected to a downstream-side main information terminal of a connector member on the upstream side.
