What it is A photoelectric switch that uses transducers and a synchronized loop gating circuit to detect the presence or absence of an object by beam blocking or reflection. All objects that reflect light can be detected. How it works The test object blocks or reflects the emitted beam, and the synchronized loop gating circuit analyzes the signal to determine presence or absence. The system can detect any object capable of reflecting light. Key benefits Noncontact sensing reduces wear and contamination risk on moving parts. Detects any lightreflective object within the sensing path, offering flexible applicability. reliability through delay control and timing broadening, external synchronization capability, and antiinterference design. Supports stable operation and includes selfdiagnosis features for easier maintenance. Key attributes Function: presence/absence detection via beam blocking or reflection. Detection principle: photoelectric switching using a synchronized loop gating circuit. Synchronization: external synchronization capability to coordinate with other equipment. Reliability: antiinterference design with delay/broadening features and selfdiagnosis. Size and material: not specified in the provided information; please consult the datasheet for exact dimensions and construction details. Performance: designed for stability and dependable operation in environments requiring coordinated sensing. Applications and use scenarios Conveyor line item detection: detect the presence or absence of items on a belt to trigger downstream processes such as routing, sorting, or stopping equipment. Packaging and labeling stations: verify correct item position before processing to ensure accurate labeling or packaging steps. Automated systems with external synchronization: integrate with PLCs or other sensors to coordinate timing and enhance overall system stability, supported by selfdiagnosis for proactive fault detection.
