1. Hygienic Safety Scanner Overview
The Schmersal SLB440-ER-1-ST-H is an advanced laser scanner engineered for demanding environments requiring high hygiene standards. Featuring 275° scanning coverage with Enhanced Resolution (ER) technology, it achieves ≤30mm object detection accuracy at 8m range. The "ST" suffix denotes Synchronization/Trigger capability for multi-scanner coordination, while "H" signifies hygienic IP69K-rated stainless steel housing (AISI 316L). Certified to ISO 13849-1 PL d (Category 3) and IEC 62061 SIL 2, it operates at 24V DC within -30°C to +80°C, resisting high-pressure washdowns (100 bar), steam cleaning, and pH 1-14 chemicals. Integrated 360° LED halo provides multi-color status visualization, making it ideal for food processing, pharmaceutical, and cleanroom applications where sanitation and collision avoidance are critical.
2. Key Technical Parameters
- Safety Ratings:
- PL d (ISO 13849-1 Cat. 3) / SIL 2 (PFHD: 8.9×10⁻⁹/h)
- Scanning Performance:
- Range: 8m (standard), 30m (with reflectors)
- Angular Resolution: 0.25°
- Scanning Frequency: 40Hz
- Environmental:
- IP69K (IEC 60529)
- Chemical Resistance: Resists acids/alkalis/sanitizers
- Electrical:
- Voltage: 24V DC ±15%
- Interfaces: 2× OSSD, PROFIsafe, EtherNet/IP
- Materials:
- Housing: Electropolished SS316L (Ra ≤0.4μm)
- Window: Sapphire glass (scratch-resistant)
- Special Features:

- Automatic lens contamination detection
3. Targeted Industrial Applications
This scanner excels in hygiene-critical automation:
- Food Processing: AGV navigation in CIP washdown zones with daily sanitation
- Pharmaceutical: Sterile area monitoring in isolators (GMP Grade A/B)
- Beverage Production: Mobile robot safety in bottling halls with caustic cleaning
- Medical Device Manufacturing: Collaborative robot cells in cleanrooms
- Automotive Paint Shops: AGV collision avoidance in solvent-rich environments
- Biotech Labs: Biohazard material handling robots
- Dairy Facilities: Yogurt filling line mobile platforms
- Packaging Sterilization: Autoclave transfer vehicle safeguarding
Its hygienic design eliminates crevices where bacteria could proliferate, while synchronization prevents interference in multi-AGV fleets.
