Nowadays, when comfort and safety become priorities in everyday life, gate automation is becoming more and more popular. One of the key elements of these systems are gate photocells, which ensure safe and failure-free operation of automatic gates. In this article, we will take a closer look at photocells and various accessories for them, available in the Ster-Tronic store.

Photocells for gates: What are they?

Photocells are optoelectronic devices that are used to detect obstacles on the path of the moving part of the gate. They usually consist of a transmitter and a receiver that create an invisible beam of light. When this beam is interrupted by any object (for example, a car or a person), the photocell sends a signal to the gate control unit, which stops its movement or reverses it. Thanks to this, photocells significantly increase user safety and minimize the risk of damage to the gate or vehicle.

Types of photocells

There are several types of photocells available on the market, which differ in design and operation:

  1. One-way photocells: The simplest type of photocells, consisting of a transmitter and receiver mounted opposite each other. The transmitter emits a beam of light that the receiver receives, thus creating a light barrier.
  2. Two-way photocells: In this type, both the transmitter and receiver are located on both sides of the crossing, and a light beam extends between them. The advantage of this solution is greater resistance to external interference.
  3. Reflective photocells: In this case, the transmitter and receiver are located in one housing, and the light beam is reflected from a special reflector mounted opposite. This solution is easy to install and adjust.

Photocell accessories

Photocells for gates often require appropriate accessories to operate efficiently and effectively. In the Ster-Tronic store you will find a wide selection of accessories that increase the functionality and reliability of gate automation systems:

  1. Protective housings: They protect photocells against mechanical damage and the influence of atmospheric factors such as rain, snow or dust.
  2. Headlights: Necessary for reflective photocells, they ensure proper reflection of the light beam, which is crucial for the operation of the system.
  3. Cables and connectors: High-quality cables and connectors ensure a stable electrical connection between the photocells and the gate control panel.
  4. Mounting brackets: They enable precise and stable mounting of photocells in the right place, which is crucial for their proper operation.
  5. Communication modules: They allow the integration of photocells with various building automation systems and enable remote monitoring and control of the gate.


Photocells for gates and appropriate accessories are an indispensable element of modern gate automation systems. They ensure safety, comfort and reliability of use, which is especially important in places with high traffic, such as housing estates or industrial facilities. In the Ster-Tronic store you will find a wide range of photocells and accessories that will meet even the most demanding needs. Whether you need simple one-way photocells or more advanced reflective solutions, you're sure to find something for yourself. We invite you to familiarize yourself with our offer!
