Photoelectric Switch Principle The device emits a light beam and detects the presence or absence of an object by the object blocking or reflecting the beam through a synchronized loop gating circuit. Any object that can reflect light can be detected. Characteristics Adjustable delay and pulse width to match system timing External synchronization capability for multisensor coordination immunity to ambient light and electrical noise Stable operation across varied regional environments Builtin selfdiagnostic capability to simplify maintenance Advantages Enables reliable detection over practical distances in automation setups Strong resistance to interference from ambient light and electromagnetic sources Robust performance in environments with electrical or magnetic disturbances Key benefits for customers Improves automation reliability by accurately detecting presence or absence of parts, products, or obstructions Reduces false detections through enhanced antiinterference features and synchronization options Easy to integrate with existing control systems via synchronization and selfdiagnostic functions Flexible timing control with adjustable delay to fit different process speeds Technical notes Function: presence/absence detection via beam blocking or reflection Compatibility: designed for use in automation systems requiring lightbeam based sensing and external synchronization Performance: reliability, antiinterference, adjustable timing, selfdiagnostic capability Use scenarios Conveyor line with item presence detection to control stop/start or counting Automatic doors or safety guards using presence sensing for interlocking Packaging or sorting stations where position verification of items is required to trigger downstream processes Applications Material handling and logistics Manufacturing and packaging lines Automated access control and safety systems
