1. Product Overview
The Schmersal ZQ 700-02 is a high-security electromechanical safety switch engineered for critical guard door monitoring in industrial automation. Featuring a robust zinc die-cast housing (IP67 rated), this device utilizes a dual-channel coded cam actuator to prevent defeat attempts while monitoring hinged/sliding guards. Certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3, it employs force-guided positively driven contacts that guarantee safe-state switching during component failures. The "02" suffix denotes dual-channel monitoring capability with integrated diagnostics. Designed for harsh environments (-25°C to +70°C), its corrosion-resistant construction withstands oils, coolants, and mechanical impacts. Integrated LEDs provide visual status for guard position, diagnostics, and power status, while the unique key-coded actuator system ensures only authorized access.

- Fault Response:
- Contact welding forces NO contact open
- Red LED illuminates during faults
- Reset Protocol:
- Manual key-turn required after guard closure
- System validates contact separation
