A limited reflection type sensor which irradiates exit light from a light emitting unit toward an object sensing region through an exit light lens and receives, at a light receiving unit, reflected light from an object existing in the object sensing region through a reflected light lens, may include a casing including a latching portion formed on a side surface and a first opening facing the object sensing region, the casing accommodating the light emitting unit and the light receiving unit; and a lens part including a light incident/exit part formed integrally with the exit light lens and the reflected light lens, and a side surface covering part in which an end of the light incident/exit part is extended along the side surface, in which the lens part covers the first opening with the light incident/exit part and the side surface covering part is latched by the latching portion.

Limited reflection type sensor

A photosensor is provided with a sensor circuit assembly. The sensor circuit assembly includes alight emitter, a light receiver, a light-emitter support, a light-receiver support, and a connecting part. The light emitter and the light receiver face each other. The light-emitter support extends from and supports the light emitter. The light-receiver support extends from and supports the light receiver. The connecting part connects one end of the light-emitter support with one end of the light-receiver support. The connecting part includes a seal and a connection terminal that protrudes from the seal. The connection terminal includes a first press-contact part, and a first pressure part that presses the first press-contact part in a press-contact direction.

Photosensor including sensor circuit assembly with light emitter and receiver that face each other

A photosensor includes a sensor module in which emitter and receiver leads protrude from a circuit-encapsulating portion in a direction intersecting with a direction in which an external connecting terminal extends. The photosensor includes a light emitter, a light receiver, a circuit-encapsulating portion, a connecting terminal, first and second emitter leads, and first and second receiver leads. When the connecting terminal extends in a first direction, and a first plane is parallel to the first direction, the first and second emitter leads protrude from the circuit-encapsulating portion in a direction parallel to the first plane and intersecting with the first direction, and extend opposite to the first direction. The first and second receiver leads protrude from the circuit-encapsulating portion in the direction parallel to the first plane and intersecting with the first direction and opposite to a direction in which the first and second emitter leads protrude, and extend opposite to the first direction. The first and second emitter leads and the first and second receiver leads are deformed to allow the light receiver and the light emitter to face each other.

A photosensor includes an emitter element, an emitter-encapsulating portion, a receiver element, a receiver-encapsulating portion, a circuit portion, and a circuit-encapsulating portion. The emitter-encapsulating portion encapsulates the emitter element. The receiver-encapsulating portion encapsulates the receiver element. The circuit portion includes a luminous element for indicating an operation. The circuit-encapsulating portion encapsulates the circuit portion. The circuit-encapsulating portion includes an operation indicator portion facing the luminous element. The emitter-encapsulating portion, the receiver-encapsulating portion, and the circuit-encapsulating portion are connected to one another with a conductive leadframe. The emitter-encapsulating portion, the receiver-encapsulating portion, and the circuit-encapsulating portion are formed from the same resin material containing a light diffusing agent.
