Multi-beam photoelectric sensor and its mount

摘要

A multi-beam photoelectric sensor (10) includes a light emitter and a photo detector each having an elongate casing (13). At least one of opposite lengthwise ends of the casing (13) is configured to receive a cable (53) for electric coupling. The casing (13) has a mount (20) located around its back surface within the length of the casing (13) to fix the casing (13) to an external structure.
