A photoelectric sensor is adapted for use in specific applications which require the additional attachment of a circular polarizer. A piece of circular polarizer material is general disc-shaped with two planar surfaces and a peripheral circular surface. The outer periphery of the disc-shaped circular polarizer is encapsulated within a generally annular molded rim. The molded rim is provided with a protrusion that is generally circular and extends from one of the generally flat surfaces of the rim material. The protrusion facilitates the attachment of the rim to the operative face of a photoelectric sensor through the process of ultrasonic welding. Advantages achieved by this device include the facilitated attachment of the circular polarizer to a photoelectric sensor, the protection of the outer peripheral edges of the laminations of the circular polarizer and the avoidance of distortions of the circular polarizer during the manufacturing process.
