Applications

The Omron E3K photocell is widely used in commercial and industrial gate automation, overhead door systems, and access control installations. Its retro-reflective design simplifies wiring by requiring power and signal connections on only one side of the opening. The reflector is mounted on the opposite side, bouncing the infrared beam back to the photocell to detect the presence of vehicles, pedestrians, or obstructions. This makes it an excellent choice for:

• Sliding and swing gate systems
• Commercial overhead doors
• Parking garage entrances
• Loading dock doors
• Any exterior opening requiring reliable obstruction detection
