ESA Safety Light Curtain for Press Machines Genuine Product from ESPE
Safety is the Foundation of Productivity
🛡️ Prevent Catastrophic Accidents
The **ESA safety sensor** instantly detects intrusion into the danger zone, sending a safety stop signal in milliseconds to prevent pinching, crushing, or cutting accidents, providing absolute protection for the operator.
✅ Comply with Safety Standards
Meets and exceeds the strictest machine safety standards such as **IEC 61496 (Type 4)** and **ISO 13849-1 (PLe)**, helping the factory easily pass occupational safety audits.
📈 Increase Productivity & Efficiency
Replacing bulky mechanical barriers, the **ESA safety curtain** allows operators quicker access to the machine, reducing cycle times and optimizing workflow, thereby improving overall productivity.
⚙️ How It Works
🏭 Typical Applications
• Mechanical presses, servo presses, hydraulic presses.
• Press Brakes, Shearing Machines.
• Industrial robot work areas, automated assembly lines.
• Injection molding machines, die-casting machines, and other types of machinery with hazardous movements.
Outstanding Technical Features of ESPE ESA
⚡ Response Time Under 20ms
Extremely fast response time ensures the machine stops before an accident can occur, which is crucial for high-speed and short-cycle press machines.
🎯 Precise Resolution
**ESPE** offers multiple resolution options from 10/20mm (finger protection) to 30/40mm (hand protection), meeting all specific safety requirements.
🔩 Durable in Industrial Environments
A sturdy aluminum profile housing, IP65-rated for protection against dust and water jets, along with strong vibration resistance, ensures stable operation in harsh factory environments.
💡 Easy Integration & Diagnostics
The **ESA sensor** is equipped with dual OSSD safety outputs (PNP/NPN), compatible with all types of safety relays or PLCs. Status indicator LEDs make installation and troubleshooting quick and easy.
