Photoelectric sensor having a light guide built-in |
摘要 |
In a photoelectric sensor, a photosensitive device is mounted on a substrate and outputs an electric signal corresponding to light incident thereto. A casing holds the substrate in a bore formed therein and includes a light guide portion formed of an optically transparent material for conducting incident light to the photosensitive device. A light emitting device is also mounted on the substrate for emitting light in response to a current input thereto. A seal member is molded to air-tightly seal the light emitting device and photosensitive device except for a light guide portion included in the light emitting device and a light guide portion included in the photosensitive device.
