PNI CEL135 Photocell SetPNI CEL135 is a set of photocells designed for integration into automatic gate opening systems (sliding or swing gates). This type of equipment belongs to the category of photoelectric sensors, which detect the presence or passage of objects by interrupting a beam of infrared light. In the context of car access automation, these photocells protect users and vehicles, ensuring the safe operation of the automated system. |
What are photocells and how do they workPhotocells are photoelectric devices that emit and receive a beam of light — in the infrared spectrum — between two components: a transmitter and a receiver. When the light beam is interrupted (e.g. by a car or a person passing through the monitored area), the receiver detects this change and transmits an electrical signal to the gate automation controller. This operation allows the automatic system to stop or reverse gate movement, preventing accidents and equipment damage. Such a system is very useful for protecting automatic entrances and avoiding collisions with obstacles. |

Main characteristics of PNI CEL135 photocellsPNI CEL135 photocells use infrared technology and are composed of two units: a transmitter unit and a receiver unit. The transmitter operates independently powered by batteries, and the receiver connects to the gate automation control unit, usually at a supply voltage of 12–24 V AC/DC. The system has a detection distance of up to about 9 m, making it suitable for medium and large sized gates. The photocell housing offers an IP45 degree of protection against external factors, which allows for use in outdoor environments with various weather conditions. |
Installation and configuration in the automation systemThe installation of PNI CEL135 photocells involves mounting the two units face to face, on the poles or side structures of the gate, at a height that allows efficient detection of vehicles and pedestrians. The transmitter and receiver must be properly aligned for the infrared beam to be received without interruption. The receiver connects to the gate automation control unit, using the terminals dedicated to the safety, and the power supply is carried out at the voltage accepted by the system. Setup is simple, only requiring verification of correct operation by testing the gate reaction to beam interruption. Correct installation ensures stable detection, reduces false alarms and contributes to the safe and reliable operation of the entire automated system. |
