Abstract: Provided is an ultrasonic flow switch which can be stably mounted on pipe. A clamp part is mounted on an outer surface of the pipe. A casing part which integrally or independently holds the first and second ultrasonic wave elements is fixed to the clamp part by a sensor fixing screw. The clamp part is configured to restrict displacement of the casing part in an axial direction of the pipe and in a circumferential direction of the pipe and to allow displacement of the casing part in a radial direction of the pipe in a state where the casing part is not fixed.

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: A photoelectric sensor includes a connecting section for light projection to which a light propagation member for light projection optically coupled to a light emitting element is connected, a connecting section for light reception to which a light propagation member for light reception optically coupled to the light receiving element is connected, a signal generating unit configured to compare a light reception signal generated by the light receiving element and a threshold and generate a detection signal indicating a result of the comparison, a first light emitting element for indication optically coupled to the connecting section for light reception, and a mounting substrate on which each of the first light emitting element for indication and the light receiving element is positioned in the connecting section for light reception or one of the first light emitting element for indication and the light receiving element is positioned via the other.
