A variety of industries rely on different equipment pieces, machines, and tools to ensure their daily processes are conducted optimally and seamlessly. One of the things they take advantage of is the sensors, particularly photoelectric sensors. Photoelectric sensors are devices that utilise light to detect the presence, absence, or specific characteristics of an object. They are widely used in various industrial applications to carry out tasks like object detection, counting, sorting, and measuring.

One maker of photoelectric sensors that is popular today is Leuze.

An Overview of Leuze Photoelectric Sensors

As mentioned earlier, photoelectric sensors are devices that generally use light, typically infrared or visible, to detect the presence, absence, or specific properties of an object. They can also identify and measure distances of objects. Leuze photoelectric sensors work on the principle of sending a light beam from the sensor to a target and measuring the reflection, absorption, or interruption of the light.

Sensors from Leuze are often comprised of three main components. The first component is the light source, which can be visible or infrared. The second one is the receiver, which detects the light’s reflection, absorption, or interruption. The last component is the control electronics. They are meant to process the signal received by the receiver and provide output based on the target’s characteristics.

Leuze Photoelectric Sensors: Major Models

Various models of Leuze photoelectric sensors can be maximised by industrial operations. These models include the following.

• Through-beam Sensors: Through-beam sensors consist of a separate emitter and receiver. They work by detecting when an object interrupts the light beam between them.

• Retro-reflective Sensors: Retro-reflective sensors, alternatively, emit light that is then reflected by a reflector and detected by the receiver when the object is present.

• Diffuse Mode Sensors: Diffuse mode sensors, ultimately, rely on the reflection of light from the target object itself. They are suitable for detecting object presence and colour sensing.
