Abstract: Provided is a method of manufacturing a sensor. The sensor has a casing having an opening portion, a clamp having a recessed part on its outer periphery and having one end inserted into the opening portion, and a sealing ring attached to the recessed part and disposed between the casing and the clamp. The method includes using a first divided mold to form a first component of the clamp, the first component including a main body portion and a first part located at one end side of the main body portion and forming a part of the recessed part. The first divided mold is divided so that a dividing surface intersects the main body portion and separates in an axial direction of the main body portion.

Abstract: A sensor is provided with a cylindrical-shaped housing which has an opening formed at one end, an electronic component which is housed in the housing, a cylindrical-shaped clamp of which one end is inserted into the housing from the opening, and a sealing resin which seals the gap between the inner wall of the housing and the outer wall of the clamp. On the outer wall, the clamp has a rib which rises towards the inner wall of the housing. The rib includes an apex and a sloped surface which extends from the apex towards another end of the clamp and which intersects the outer wall of the clamp. The sealing resin, which exudes from between the inner wall of the housing and the apex and which is positioned on the sloped surface, has a recess resulting from surface tension.

Abstract: This proximity sensor includes: a cylindrical housing having an opening at one end in the axial direction; a detection part housed at the other end of the housing and detecting the presence or absence of a detection target contactlessly; a substrate housed in the housing and mounted with a control circuit for controlling the detection part; a detection part shield preventing external noise from entering the detection part and including a first face part adhered to the front surface on the other side of the detection part, and a side face part configured from multiple side pieces connected to the outer periphery of the first face part and bent from the first face part to cover the side surface of the detection part; and a resin provided around the detection part and the detection part shield.

Abstract: A proximity sensor in which generation of voids in a resin sealing portion sealing an inside of a housing can be suppressed and thus a yield is improved. The proximity sensor includes a housing, a detection coil, a circuit board and a resin sealing portion. The circuit board is accommodated in the housing to partition an internal space of the housing, and the resin sealing portion covers at least a part of the circuit board by filling the internal space of the housing and thus seals a covered portion of the circuit board. A resin injection port configured to inject a liquid resin forming the resin sealing portion by curing the liquid resin is provided in the housing, and a cutout portion having a notch shape or an opening shape is provided in the circuit board to include at least a part of a portion facing the resin injection port.

Abstract: To ensure omnidirectional visibility of a proximity sensor with high luminance using a single light emitting element. A proximity sensor (1) includes a substrate (14) on which a control unit (20) is formed and in which a normal direction of the substrate is perpendicular to an axial direction of a coil section (13), a light emitting element (15) which emits light in the axial direction on the substrate, a light diffusion section (16a) which diffuses emitted light in a direction other than the axial direction, and a light guide section (16b) which guides diffused light to a display section (21) on a side surface.

Abstract: The proximity sensor (1) includes a core (3) configured to hold a coil (2), a board (5) on which a proximity detection circuit is mounted, and an intermediate component which is a fixing member (4) formed of a resin to fix the board to the core and has a conductive pattern configured to electrically connect the coil and a wiring provided on the board.
