WHAT ARE THE DIFFERENT TYPES OF PHOTOCELLS

What is a photocell?

Point definition

The PHOTOCELLS, also known as photoelectric cells, are devices that use beams of light to detect the presence of obstacles in the gate’s path as it opens or closes. They are frequently used in automation and control systems to trigger an action based on light levels.

How PHOTOCELLS Work

The way they work is quite simple: a pair of PHOTOCELLS typically installed on either side of the gate’s opening. When the light beam between the two cells is interrupted by an object, it triggers a signal that stops or reverses the gate’s movement, thereby preventing potential collisions with people, vehicles, or other obstacles. Thanks to this technology, PHOTOCELLS greatly PHOTOCELLS to user safety and the protection of property. They are therefore essential in any modern gate automation system.

4 Types of PHOTOCELLS Know About

There are various types of PHOTOCELLS. Each photocell has its own advantages and disadvantages in terms of accuracy, range, and operating environment.

Here's an overview of the main types:

- Reflex photocell: uses a built-in light source to emit a reflected beam from a target object to the sensor on the same unit. Ideal for detecting opaque objects such as metal or plastic.

- Barrier photocell: consisting of a transmitter-receiver pair separated by a fixed distance. When an object cuts the light beam between the two, detection is activated. Useful for measuring distances and dimensions with precision.

- The slit photocell: uses a narrow slit as the light source and an opposite receiver as the sensor. When an object partially blocks the light, detection is triggered. Often used to detect thin objects such as paper or plastic.

 - Proximity sensor: Uses a magnetic or electric field to detect metal objects. Suitable for harsh environments where other types of PHOTOCELLS not work.

In short, the choice of photocell type will depend on the object to be detected, as well as environmental and operational conditions. By understanding the different options available and their respective advantages, you'll be able to select the one best suited to your specific application.

PHOTOCELLS product lines to meet your needs

As a manufacturer of electronic systems for automatic gates, Prastel offers a wide range of PHOTOCELLS designed for various applications:

 - Surface-mounted: These PHOTOCELLS installed directly on the wall. They provide effective detection while remaining visible and easily accessible for maintenance. (e.g., FOTO30-A / FOTO30-B)

  - Flush-mounted in the wall: For a more discreet look, these PHOTOCELLS be installed flush with the wall. They blend seamlessly into the surrounding architecture while ensuring accurate detection. (e.g., FOTO35)

  - Recessed into the door jambs: Ideal for discreet integration, these PHOTOCELLS installed in the door jambs, ensuring detection while maintaining a clean, streamlined appearance. (e.g., CR10MS / CR15NM)

Prastel also offers two types of cell configurations:

 - Fixed-mount unit: The two PHOTOCELLS positioned opposite each other, providing standard detection for various residential and commercial applications. (e.g., FOTO30-A/FOTO30-B)

 - Steerable cell: this configuration allows the beam to be steered flexibly, simplifying installation and adapting to the specific needs of each project. (ex :FOTO-R/FOTO-RB)

But that's not all. Prastel has also designed a number of specific options to suit different environments:

- Classic plastic cell: suitable for residential and collective environments, this version offers reliable detection in a sturdy, attractive housing (e.g. FOTO-R/FOTO-RB).

- Vandal-proof cell: designed for industrial environments, this version features a resistant metal cover, offering additional protection against intentional damage. (e.g. FT30-AV)

As you can see, we offer a complete line of PHOTOCELLS for a variety of applications. Our goal? To ensure that users have reliable and safe detection for all their needs. To learn more, please feel free to contact us!
