You may be wondering: If I’ve got a photoeye sensor on my gate, do I really need a safety edge too? The short answer: In most cases — yes. These two entrapment protection devices offer security, but in different ways.
Photoeyes use an invisible infrared beam between a transmitter and receiver. If something interrupts the beam while the gate is closing, it reverses direction. They’re great at detecting objects in a fixed zone, but they can’t detect pressure or contact. Safety edges, on the other hand, are pressure-sensitive strips mounted on the gate edge. If the gate comes into contact with a vehicle or person, the edge compresses and sends a signal to stop or reverse the gate.
Now the key question: Why do you need both of these entrapment protection devices? These products protect in different ways. Photoeyes detect presence; safety edges detect impact. UL325 regulations often require two independent entrapment protection devices per direction of travel. Using both ensures full compliance and maximizes user safety — critical when liability is on the line.
Pro Tip: EMX offers UL325-compliant photoeyes and safety edges that are reliable, easy to align, and compatible with most gate operators. Let’s take a closer look at them here.
Examining EMX’s Entrapment Protection Devices
For greater functionality and performance, we offer the Wireless Edge Link. The WEL-200 operates up to 200 feet line of sight between the transmitter and receiver, and its wireless capabilities simplify the installation process. Built for convenience and reliability, this product boasts a long battery life, operating up to two years on two AA lithium batteries.
The WEL-200 features several elements that aim to improve the user experience. Our real-time signal quality display allows you to determine connection quality, and a durable housing is capable of withstanding difficult outdoor conditions. The receiver can also connect with up to four transmitters, provides separate relay and pulse outputs for open and close edge functionality, and offers a versatile entrapment protection solution.
Another quality option is our IRB-RET2. This RetroReflective Photoeye is compact and easy to install. With its 60-foot operating range and rugged enclosure, this is an ideal choice for indoor and outdoor use on automatic gates and doors. This device is versatile and easily integrates with other products, which is perfect for use with safety edges. Best of all, it offers peace of mind with its Selectable Stealth Mode, which turns off sensor LEDs after 30 seconds of no obstructions, adding extra security and deterring vandalism.
Finally, our IRB-MON2 offers a more expansive operating range of 115 feet. With UL325 monitoring and a thru-beam configuration, this entrapment protection device has four monitoring interfaces, making for a better overall user experience. If you’re looking for seamless installation and wiring, this product is a reliable, high-performing solution.
