Reflection light scanners
Diffuse sensors are optical sensors for detecting objects. They consist of a transmitter and a receiver located on the same side of the sensor. The transmitter generates a light signal that is directed at the object to be detected. The light signal is reflected by the object and detected by the receiver.
The receiver generates an electrical signal when the reflected signal reaches a certain intensity. The electrical signal is processed by an electronic circuit to detect the presence of the object. Diffuse sensors are usually designed for use at close range and can be used in a variety of applications.
Diffuse sensors are often used in industry to detect the position of workpieces on conveyor belts or the presence of machine parts in automated production lines. They are also used in automotive and logistics applications to detect the presence of objects on a conveyor belt or on the road.
Advanced diffuse sensors can also be combined with other sensors, such as ultrasonic or angle sensors, to provide even more accurate measurements. They can also be digitally displayed and connected to other systems, such as an automatic control system, to optimise the production process and increase efficiency.
Diffuse sensors are an effective and cost efficient method of detecting the presence of objects and can be used in many applications.

Background suppression
Poorly reflecting surfaces of the measuring object or disturbing background reflections can lead to incorrect measurements. The use of diffuse reflection light scanners with background suppression is recommended here. Not only the reflected light quantity is detected, but also the angle of the reflected light is evaluated. The angle information (triangulation) can then be used to determine whether the reflected light originates from the measured object. For example, interfering light reflections from reflective materials in the vicinity of the measurement object can be optically suppressed. The targets are detected relatively independently of the target surface.
Front blanking
In contrast to background blanking, diffuse sensors with foreground blanking are also offered. These are mainly used when the target itself has relatively poor reflective properties, but the background of the target reflects well. If the reflected light of the background is interrupted by the measuring object, this interruption is evaluated by the light sensor.
Light-switching diffuse reflection sensor
If transmitted light falls on the receiver because the target does not interrupt the light beam, the switching function is triggered. Conversely, if the transmitted light does not fall on the receiver because a measuring object interrupts the light beam of the transmitter, switching does not take place. No measuring object in the light beam: the output is not switched There is measuring object in the light beam: the output is switched
Dark switching diffuse reflection light scanners
If no transmitted light falls on the receiver because the measuring object interrupts the light beam, the switching function is triggered. Conversely, if the transmitted light falls on the receiver because no measuring object interrupts the light beam of the transmitter, the output is not switched. No measuring object in the light beam: the output is switched. Measuring object in the light beam: the output is not switched.
Combined photoelectric proximity switches with the functionality of the photoelectric proximity switch and the distance measurement function are also offered. These sensor types can also be found in diribo under the light scanners.
Detection range
The detection range is the space in which the switching distance of an optoelectronic sensor to the standard plate can be set

What is a diffuse reflection sensor and how does it work?
A diffuse sensor is an electronic component that is used to detect objects or recognize positions. It consists of a light source, a receiver and a reflector.
The light source emits a beam of light that hits the reflector and is reflected by it. The receiver detects the reflected light and converts it into an electrical signal. If an object is located between the light scanner and the reflector, the reflected light is blocked and the receiver detects a change in the light.
The diffuse reflection sensor works on the principle of the reflectivity of surfaces. Different surfaces have different degrees of reflection. If the object has a high reflection, more light is reflected and the receiver detects a strong signal. If the object has a low reflection, less light is reflected and the receiver detects a weaker signal.
The diffuse reflection sensor is often used in industrial applications to detect objects, monitor positions or serve as a switch in automation systems.

What is the difference between a diffuse reflection light scanner and a transmitted light scanner?
A diffuse reflection light scanner and a transmitted light scanner are two different types of light scanners that differ in the way they work.
A diffuse reflection sensor uses a single sensor to send and receive light. The light is reflected by an object and directed back to the sensor. When the reflected light reaches the sensor, the diffuse reflection sensor detects the presence or absence of the object. The sensor detects the change in light intensity when the object is present and emits a corresponding signal. Diffuse sensors are often used for applications where the object must be detected without touching it, such as in automation technology.
A diffuse sensor consists of two separate sensors, a transmitter and a receiver. The transmitter sends light through an object, and the receiver detects the light that passes through on the other side of the object. When the light reaches the receiver, the diffuse sensor detects the presence or absence of the object. If the object is present, the light is blocked by the object and the transmitted light sensor emits a corresponding signal. Diffuse sensors are often used for applications where the object must be detected by shining a light through it, such as in quality control or when counting products.
To summarize, a diffuse reflection sensor detects the reflected light of an object, while a transmitted light sensor detects the light that passes through an object.

What factors can influence the accuracy and reliability of a diffuse reflection sensor?
The accuracy and reliability of a diffuse reflection sensor can be influenced by various factors, including
1. Surface properties: The nature of the surface to which the light scanner is aligned can influence the reflection of the light. Unevenness, unevenness or dirt on the surface can lead to inaccurate or unreliable measurements.
2. Ambient light: The brightness of the surroundings can influence the measurements of the light sensor. Strong light sources in the vicinity of the sensor can cause the reflected light to be superimposed and lead to incorrect results.
3. Installation conditions: Correct installation and alignment of the diffuse sensor is important to ensure accurate measurements. An incorrectly aligned sensor can lead to inaccurate or unreliable results.
4. Malfunctions: Electronic faults or interference can impair the performance of the light scanner. Electromagnetic interference from other devices or electrical components can lead to faults or failures.

What different types of diffuse reflection sensors are there and what attributes do they have?
There are various types of diffuse reflection light scanners, including:
1. One-way diffuse sensor: With this type of diffuse sensor, the light is emitted by a light source and reflected back by a reflector or the object to be detected. The receiver detects the reflected light and emits a signal when the light is interrupted. This type of diffuse sensor is well suited for applications where the object to be detected is not transparent.
2. Opposite reflection light scanners: With this type of diffuse sensor, the light is emitted by a light source and reflected back by a reflector. The receiver detects the reflected light that is reflected by an object between the push-button and the reflector. If the reflected light is interrupted, the receiver emits a signal. This type of diffuse sensor is well suited for applications where the object to be detected can be transparent.
3. Background suppression light scanners: With this type of diffuse sensor, the light is emitted by a light source and reflected by the object to be detected. The receiver detects the reflected light, but ignores the light reflected from a background. This type of diffuse sensor is well suited for applications where the object to be detected is located in front of a background.
4. Transmitted light diffuse sensor: With this type of diffuse sensor, light is emitted from a light source through the object to be detected. The receiver detects the light passing through the object and emits a signal when the light is interrupted. This type of diffuse sensor is well suited for applications where the object to be detected is transparent.
The attributes of diffuse reflection sensors vary depending on the model and manufacturer, but in general they are characterized by high sensitivity, fast response times, easy installation and reliability.

What other functions or features can diffuse reflection light scanners have, e.g. background suppression or an adjustable range?
Some of the other functions or features that diffuse reflection sensors can have are:
1. Background suppression: Diffuse sensors can be configured so that they block out the background or ambient light and only detect the reflected light from the object. This improves the reliability of detection, as interference from other light sources is minimized.
2. Adjustable range: Diffuse reflection light scanners can usually be set to have a specific range. This makes it possible to adapt the sensor to the specific requirements of an application. The range may vary depending on the model and manufacturer.
3. Switching function: Diffuse sensors can act as a switch that emits a signal when an object is detected. This signal can then be used to control other devices or processes.
4. Background suppression: Some diffuse reflection sensors have a background suppression function to prevent false alarms. This function recognizes the difference between the reflected light of the object and the background and ensures that only the reflected light is detected.
5. Multi-channel operation: Some diffuse reflection sensors can have several channels to detect several objects at the same time. This can be useful in applications in which several objects have to be detected in quick succession.
6. Analog output: Some diffuse reflection sensors offer an analog output that provides continuous measurement data. This enables more precise detection and finer control of processes.
It is important to note that not all diffuse reflection light scanners have these functions. The available functions depend on the specific model selection and the manufacturer.
