Photoelectric switch (sensor) Key benefits Reliable presence/absence detection: Uses a synchronized loop gating circuit to detect when a test object blocks or reflects the light beam, providing clear object/no-object signals. Broad compatibility: Can detect any object that reflects light, making it suitable for a wide variety of materials and shapes. Stable operation in demanding environments: Built-in anti-interference design, external synchronization, delay and pulse-broadening options, and self-diagnosis increase system stability and reduce false triggers. Easier integration and uptime: External synchronization minimizes cross-talk between sensors; self-diagnosis helps identify faults quickly to reduce downtime. Main functions and features Detection principle: Senses presence or absence by beam interruption or reflection using a synchronization loop gating circuit. Reflective detection: Works with all objects that can reflect light; no special surface treatment required for basic detection. Interference resistance: Designed to resist external electrical and optical interference for consistent performance. Timing control: Supports delay and pulse-broadening functions to match output timing to downstream equipment needs. Synchronization: External synchronization capability allows multiple sensors to operate closely without mutual interference. Self-diagnosis: Onboard diagnostics provide status feedback to help troubleshoot and maintain reliable operation. Performance and compatibility Performance focus: High reliability for continuous industrial use, stable detection region, and robust signal quality under typical operating conditions. Integration: Designed to work with automation systems that accept standard photoelectric sensor outputs; supports coordinated operation via external synchronization. Environmental considerations: Anti-interference measures improve performance in electrically noisy or optically crowded installations. Typical applications Conveyor and assembly lines: Detect parts, count items, or confirm component presence for automated assembly and quality checks. Packaging and sorting: Verify package presence, trigger indexing, or ensure correct placement before sealing or labeling. Part-positioning and safety interlocks: Confirm object position for machine operations or use as a presence sensor in interlock and gating systems. Technical notes (as provided) Detection method: Uses blocked or reflected beam with a synchronization loop gating circuit to detect presence/absence. Detectable objects: All objects that reflect light can be detected. Reliability features: Delay, broadening, external synchronization, anti-interference design, high reliability, stable working region, and self-diagnosis.
