Photoeyes

Photocells are essential safety devices installed at the gates to prevent them from closing on people or vehicles in their path. Safety photocell infrared beams emit laser beams that keep the gates open when an object is detected in their path, making them a critical component for automatic gates that can literally save lives. There are two types of photo-eyes commonly used in gate systems. The first and most common type is the reflector-based photocell, which is installed on one side of the gate while its reflector is installed on the other side, reducing the need for wiring on both sides. The second type is the less common dual-beam photoeye, which requires communication wires to be installed between both sides of the gate. While reflector-based photoeyes can be affected by poor weather conditions and give out false readings, dual-beam photoeyes are generally more stable and less prone to false readings. Regardless of the type used, photocells are a critical safety feature for gate systems and should always be properly installed and maintained to ensure the safety of people and vehicles.
