Photoelectric switch sensor - How it works The object either blocks or reflects the light beam. A synchronized loop gating circuit detects presence or absence of the object. Any object that reflects light can be detected. - Key features Delay timing with adjustable control External synchronization input for system-wide timing Anti-interference design for reliable operation in challenging environments High reliability with stable operation and self-diagnosis Designed to support regional stability - Benefits Provides fast, accurate detection to control automation processes Reduces false triggers and misdetections Enables reliable process control and built-in diagnostic capability - Compatibility and notes Intended for integration with standard industrial control systems via synchronization interfaces Size, housing material, and exact interface vary by model; refer to the datasheet for details - Use scenarios 1) Conveyor line item presence detection for counting or gating 2) Packaging or labeling line to verify product presence before processing 3) Safety interlock to ensure safe machine access and automatic shutoff, with self-diagnostic status lightly indicating health of the sensor
