Laser Safety Micro Switch Sensor
Ultra-Slim Through-beam Photoelectric Sensor (4.5mm Profile) with Robust Design & Adaptive Intelligence for Confined Spaces
This 4.5mm-thin sensor delivers stable, interference-resistant detection in narrow gaps while prioritizing durability. Its metal enclosure with resin-potted internals ensures shock resistance and IP67-rated environmental protection, making it ideal for harsh industrial environments.
Key Technical Advantages:
- Through-beam Detection for Transparent Objects
- Adopts modulated pulse-emission technology and a proprietary algorithm to suppress ambient light interference (e.g., sunlight, fluorescent flicker), eliminating the need for additional shielding.
- Reliably detects clear, translucent, or reflective targets (e.g., glass, films, PET bottles) via precise optical beam control.
- Auto-Sensitivity Optimization
- Integrates dynamic auto-gain control that adjusts detection thresholds in real-time based on received light intensity, minimizing false triggers caused by target color variations, surface gloss, or angular misalignment.
- Industrial-Grade Resilience
- Ruggedized construction: Sealed metal housing with resin encapsulation shields against dust, moisture, and mechanical vibration.
- Long-term stability: Maintains consistent performance across -25°C to +60°C with <1% sensitivity drift.
Technical Selection Guide:
- Optimal for:
- Conveyor systems with ≤5mm clearance (e.g., miniature packaging lines, lab automation).
- Applications requiring transparent material handling (e.g., pharmaceutical blister packs, display panel assembly).
- Key Specs to Prioritize:
- Response time: ≤50μs for high-speed object tracking.
- Detection range: 100mm–10m (model-dependent; specify gap width).
- Output type: NPN/PNP, push-pull, or analog (for distance measurement).
Why Choose This Sensor?
-
Space-efficient: 4.5mm profile fits where conventional sensors cannot.
-
Maintenance-free: No manual sensitivity adjustments or environmental shielding required.
-
Cost-effective: Reduces downtime from false stops and simplifies integration in complex machinery.
