1. Hygienic Safety Light Curtain Overview
The Schmersal zSD-H is a Type 4 safety light curtain engineered for critical hygiene environments like food processing, pharmaceuticals, and chemical manufacturing. Featuring a stainless steel housing (AISI 316L) with IP69K protection, this system creates infrared protection fields with 14mm resolution for precise hand/finger detection compliant with ISO 13855. Certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3, it operates at 24V DC across extreme temperatures (-30°C to +80°C) while resisting high-pressure washdowns (100 bar @ 80°C), steam sterilization, and aggressive chemicals (pH 1-14). Electropolished surfaces (Ra ≤0.8μm) prevent bacterial growth, while sloped geometries ensure complete fluid drainage. Integrated multi-color LED indicators and PROFIsafe communication support seamless integration into sanitary automation systems without compromising cleaning protocols.
2. Critical Technical Specifications
This safety system delivers SIL 3/PL e performance with 14mm optical resolution across a 0.3-3m adjustable range, utilizing 24-48 configurable beams. Electrical specifications include 24V DC ±10% operation, dual PNP OSSD outputs (0.5A), and PROFIsafe/EtherNet/IP connectivity. The IP69K-rated SS316L housing withstands 100+ bar CIP/SIP cycles, while sapphire optical windows and FDA-compliant seals maintain integrity in corrosive environments. Key metrics include ≤20ms response time, beam auto-alignment with ±3° tolerance, and automatic drainage features meeting EHEDG standards. Certifications encompass 3-A 08-19, IECEx Ex ic IIIC T80°C Dc, and EC1935/2004 for food contact compliance.
3. Sanitation-Critical Applications
Designed for hygiene-first environments, this light curtain safeguards:
- Food Processing: Bone saws/cutter decks in meat plants with daily high-pressure sanitation
- Pharmaceutical Isolators: Aseptic filling lines requiring GMP Grade A compliance
- Dairy Operations: Rotary fillers undergoing steam-in-place sterilization
- Chemical Mixing: Splash zone protection against acids/alkalis
- Biotech Reactors: Personnel safety near fermentation tanks
- Vaccine Production: Perimeter security for vial capping machines
- Beverage Canning: Palletizer access points with caustic cleaning cycles
- Ready-Meal Packaging: Slicer/dicer machinery in high-moisture environments
Its crevice-free design and electropolished surfaces prevent microbial harborage while 14mm resolution detects fingers and small tools per ISO 13855 standards.
4. Operational Advantages
- Sanitary Design: Zero dead spaces (EN 1672-2 compliant) with ≥3° drainage angles
- Corrosion Resistance: Passivated SS316L withstands chloride stress corrosion and peroxide vapors
- Advanced Diagnostics: RGB LED bars provide real-time status (green=operational, red=beam breach, blue=cleaning mode)
- Intelligent Protection: Floating blanking adapts to container heights; cascade muting enables material transfers
- Environmental Resilience: Automatic lens purge during washdowns; post-cleaning drying cycle (45s @ 60°C)
- Maintenance Optimization: Quick-disconnect mounts for tool-free removal; predictive contamination alerts
- Safety Redundancy: Dual-processor cross-monitoring with ECC memory protection
- Compliance Ready: Pre-validated templates for FDA 21 CFR 177.2600 and ISO 14119
5. Safety Operation & Integration
Protection Sequence:
- Beam Monitoring: 880nm infrared scans 50×/sec with optical/hardwire synchronization
- Safety Response: Beam interruption triggers OSSD shutdown (≤20ms); muting enabled via capacitive sensors
- Hygiene Protocol: Washdown detection activates lens purge; drying cycles prevent moisture retention
- Diagnostic Hierarchy:
- Solid Green: Normal operation (OSSD ON)
- Solid Red: Beam blocked (OSSD OFF)
- Flashing Blue: Muting active
- Yellow: >80% contamination (OSSD OFF)
- Magenta: Communication loss
- PLC Integration:
- Real-time status via PROFIsafe telegrams
- Automatic field resizing based on process phases
- Contamination level monitoring through analog outputs
