1. Advanced Pressure-Sensitive Safety Mat Overview
The Schmersal SMS 5-250-500 is a 5-zone pressure-sensitive safety mat engineered for precise personnel detection in high-risk industrial areas. Featuring a 250×500mm active sensing area divided into five independent detection zones, this system triggers safety shutdowns with ≤25N actuation force (equivalent to 2.5kg load). Constructed with oil-resistant PUR top surface and IP67-rated polyurethane housing, it withstands temperatures from -25°C to +70°C while resisting hydraulic fluids, coolants, and mechanical impacts. Certified to ISO 13849-1 PL c (Category 2) and IEC 62061 SIL 1, its dual-channel OSSD outputs interface with safety controllers to halt machinery within ≤100ms. The low-profile 20mm height minimizes tripping hazards while enabling installation in confined spaces around robotic cells, press brakes, and automated assembly stations.
2. Critical Technical Specifications

3. Targeted Industrial Applications
This safety mat system excels in scenarios requiring precise operator presence detection:
- Robotic Workcells: Perimeter guarding for collaborative robots where physical barriers are impractical
- Press Brakes: Operator foot position monitoring during bending cycles per ANSI B11.3
- Packaging Machinery: Access prevention near rotating shafts on filler/capper modules
- Automotive Stamping Lines: Safety zones around transfer press entry points
- CNC Machining Centers: Tool change area protection during maintenance
- Injection Molding Machines: Mold area access control with zone-specific sensitivity
- Palletizing Systems: Detecting personnel near automated layer formers
- Conveyor Junctions: Preventing access to nip points during operation
The 5-zone configuration distinguishes between full-body presence (multi-zone activation) and accidental drops (single-zone triggers), reducing nuisance stops by 60% compared to single-zone mats.
4. Operational Advantages
- Precision Detection:
- Five independent zones minimize false triggers from dropped tools
- 20-30N actuation force ensures reliable operator detection

- Safety Integration:
- Dual OSSD outputs enable Category 2/3 safety circuits
- Automatic reset upon weight removal (0.5s recovery time)
- Environmental Robustness:
- UV-stabilized material prevents degradation in sunlight
- Resists common industrial chemicals (pH 3-10)
- Installation Flexibility:
- Interlocking edges for seamless multi-mat configurations
- Daisy-chaining support for ≤10 mats via M12 extensions
- Diagnostic Capabilities:
- Integrated test button validates circuit integrity
- Visual LED status indicator (green=operational, red=fault)
5. Safety Functionality & Integration
Three-Stage Safety Logic:
- Pressure Detection:
- Conductive layers make contact when ≥25N force applied
- Zone-specific resistance change detected
- Signal Validation:
- Dual-channel monitoring detects short circuits/breaks
- Cross-comparison ensures signal integrity
- Safety Response:
- OSSD outputs de-energize within 100ms
- Machine safety controller initiates stop category 0
