Photoelectric Switch Sensor Function and operation This is a photoelectric switch that detects the presence or absence of an object by whether the test beam is blocked or reflected. Detection is achieved through a synchronization loop gating circuit. It can detect any object that reflects light. Key benefits Noncontact sensing for fast moving items, reducing wear and maintenance. Reliable presence/absence detection based on beam interruption or reflection. Synchronization loop gating provides precise timing and stable operation. Delay function and external synchronization support easy integration with existing control systems. Antiinterference design with reliability. Selfdiagnostic capability to aid maintenance and monitoring. Features and attributes Function: detect presence or absence by beam interruption or reflection. Compatibility: supports external synchronization input for system integration. Performance: antiinterference design and reliability. Delay capability: adjustable sensing delay to fit process timing. Selfdiagnostic: builtin capability to assist in maintenance. Applications and use scenarios Conveyor line item detection to trigger downstream processes, counts, or stops. Packaging and filling lines to verify product presence before proceeding. Automatic sorting or positioning in material handling where beam interruption signals indicate position. Notes All objects that reflect light can be detected.
