PROBLEM TO BE SOLVED: To provide a photoelectric object detecting sensor capable of being fixed by a fastener member 8 easily removably by a method of fixing to a casing 1 on which the sensor is installed, in an integrated structure of a sensor body 5 and a filter 7 of the sensor 4 having a light emitting element and a light receiving element. SOLUTION: A sensor case 6 and the filter 7 are integrally molded, and the sensor body 5 is inserted into the sensor case. Then engaging projections 6f are formed on the sensor case 6, for engaging with the fastening member 8, and the sensor case 6 and the fastening member 8 cooperatively pinch the casing 1, to thereby fix the sensor to the casing. The fastening member 8 has snap-fitting pieces, and therefore the sensor is easily attached to/detached from the casing. COPYRIGHT: (C)2004,JPO |
