Frame light barriers
61 - 61
Frame sensors are optical sensors used to detect the presence of objects in a defined area. They consist of a frame with a series of transmitter and receiver units aligned at the top and bottom of the frame.
When an object enters the area of the frame, it blocks the light beam passing between the transmitter and receiver units. The blocked signal is detected and processed by an electronic circuit to detect the presence of the object.
Frame sensors are used in a wide range of applications including manufacturing, logistics and retail. They can be used to detect the presence of objects on a conveyor belt, to control automated machinery or as part of safety systems.
Modern frame sensors often use digital displays and can be linked to other systems, such as an automatic control system, to optimise the production process and increase efficiency.
Frame sensors are a simple and effective method of detecting the presence of objects in a given area and can be used in many applications.

What are frame light barriers and how do they work?
Frame light barriers are sensors that are frequently used in industrial and automation technology. They consist of a transmitter and a receiver unit, which are mounted opposite each other.
The function of a frame light barrier is based on the principle of the light barrier. The transmitter generates a light beam that is detected by the receiver unit. If this light beam is interrupted, for example by an object or a person, a signal is triggered.
There are various types of frame light barriers, such as retro-reflective sensors, through-beam sensors and diffuse reflection sensors. With retro-reflective sensors, the light beam is reflected by the object and detected by the receiver unit. Through-beam sensors consist of a transmitter and receiver that are placed directly opposite each other. If the light beam is interrupted, a signal is triggered. Diffuse reflection sensors work in a similar way to retro-reflective sensors, but here the light beam is reflected directly by the receiver unit.
Frame light barriers are often used to detect objects in conveyor belts, packaging machines, automated assembly lines and similar applications. They enable reliable detection of objects and are used to control industrial processes.

What different types of frame light barriers are there?
There are different types of frame light barriers that can be used depending on the application and technical requirements. Here are some of the most common types:
1. Reflection light barriers: With this type of light barrier, a light beam is sent from a transmitter to reflect off an object and back to the receiver. If the light beam is interrupted, the receiver recognizes this and emits a signal.
2. Continuous light barriers: Here, the light beam is sent from a transmitter to a receiver, which are located on opposite sides of the area to be monitored. If an object crosses the light beam and thus interrupts the connection between the transmitter and receiver, a signal is triggered.
3. Fork light barriers: This type of light barrier consists of a transmitter and a receiver that face each other and form a light beam that looks like a fork. If the light beam is interrupted, a signal is triggered.
4. Infrared light barriers: These light barriers use infrared light to detect objects. They can be available in various designs such as retro-reflective photoelectric sensors, continuous photoelectric sensors or forked photoelectric sensors.
5. Laser light barriers: This type of light barrier uses laser light instead of conventional light. They offer high precision and accuracy in object detection, but are used in certain applications due to the higher costs and stricter safety requirements.
These are just a few examples of different types of frame light barriers. Depending on the specific application and the desired functions, other variants may also be available.

This can be used to restrict access or to check whether an authorized person is entering the area.
2. Intrusion detection: Frame light barriers can also be used to detect break-ins. If a person attempts to enter a secured area and interrupts the light beam of the light barrier, an alarm is triggered. This enables a rapid response and can help to prevent or limit break-ins.
3. Machine safety: In industrial environments, frame light barriers can be used to ensure the safety of machines. If a person or object interrupts the light beam of the light barrier, the machine is stopped immediately to prevent injuries.
4. Vehicle recognition: Frame light barriers can also be used to detect vehicles. If a vehicle interrupts the light beam of the light barrier, this can be used to control traffic or monitor vehicle movements.
