ESA Safety Light Curtain for Press Machines Genuine Product from ESPE

✅ Type 4 / PLe Safety Compliant ⚡ <20ms Response Time 🔩 IP65 Dust & Oil Proof

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

1️⃣
Create a virtual shield: The Emitter of the **ESA sensor** projects a grid of parallel infrared beams to the Receiver, creating an invisible protection zone.
2️⃣
Detect intrusion: When an object (like an operator's hand) enters and interrupts any of the light beams, the Receiver fails to get the signal.
3️⃣
Send a stop signal: The internal control circuit immediately sends a safety signal to the safety PLC or safety relay, triggering an emergency stop command for the press machine.

🏭 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.
