1. Product Overview
The Schmersal EDRR5ORT is an industrial-grade emergency stop device engineered for critical machinery requiring maximum safety integrity. Featuring an 80mm Ø mushroom head with ISO-compliant yellow collar (EN ISO 13850), this device ensures instant recognition and actuation. Its glass-fiber reinforced polyamide housing (IP66/IP69K) withstands extreme environments, including high-pressure washdowns (100 bar) and temperatures from -40°C to +85°C. The switch incorporates dual-channel force-guided contacts certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3. A key-lockable twist-release mechanism prevents unauthorized resetting, while integrated tri-color LEDs provide visual status feedback. Designed for vertical/horizontal mounting with M32 cable glands or M12 connectors, it meets stringent safety requirements in heavy industries like mining, energy, and metal processing.

5. Safety Operation & Architecture
Activation Sequence:
- Emergency Press: 7mm travel with 70–120N force
- Contact Action:
- NC contacts open within 30ms
- NO auxiliary contact closes (fault signaling)
- Machine Response:
- Category 0 stop (uncontrolled shutdown)
- Red LED illuminates
Safety Mechanisms:
- Dual-Channel Monitoring:
• Contact state comparison every 10ms
• Discrepancy triggers lockout - Mechanical Backup:
• Spring-driven break independent of electronics
• Guaranteed 1.2mm contact gap - Reset Protocol:
a) Insert and turn safety key
b) Audible "click" confirms mechanism release
c) Pull mushroom head to reset position
d) Green LED validates circuit restoration
