![]() ![]() The theory of these sensors can be reflected to some reality examples. A couple of applications for retro-reflective sensors In this way, you can be more sure that the sensor only receives the light that it emitted itself. Than it is less likely that false reflections of the undesired lightsources are rebounded to the sensor. By using this attribute, only the light with the wavelength of the emitted light is reflected. This filter is making sure that light with a given wavelength is reflected and the rest of the wavelengths not. The reflector than also sends the light of these sources as a reflection to the sensor, which could lead to a wrong detection.Ī retro-reflective sensor with polarized reflector is provided with a so called polarisation filter. A retro-reflective sensor with a normal reflector can suffer interference in an application with multiple light sources. The difference is in the way the emitted light is rebounded. In the essence, a polarized reflector works exactly the same as a usual reflector. What can a polarized reflector offer on top of that? The answer is a more reliable solution. In the previous paragraph is discussed why you could choose for a retro-reflective sensor. ![]() What is a polarized retro-reflective sensor? The reflector is a stable and consistent surface compared to for example a wall or the products that pass with different shapes and colors. With this sensor, more assurance can be given for a good reflection of the emitted light. In applications where a bigger distance has to be covered, they tend to choose for a photoelectric sensor with a reflector. It happens that the emitted light is reflected in every direction and barely or no reflection will arrive in the sensor. With a photoelectric sensor without reflector, such as a diffuse proximity sensor, an object is used as a source of reflection. In this article we expose these two kinds of reflective photoelectric sensors, when these are used and which one is the best choice in what application. Is everything said now? No, because a distinction can be made between normal reflector sensors and polarized reflector sensors. Retro-reflective photoelectric sensors can perform a detection after an interruption of the light signal from a reflector. The range from Sensor partners makes a distinction between acoustic claxons and sirenes, optical signal,- and indication lights, a combination of optical-acoustic signals and signal towers. The solutions offer protection and guidance in multiple applications in the most challenging environmental conditions. Signal technology The signal technology includes a wide range of optical and acoustic signalling solutions.The sensors are used in elevators, gates, fences, parking garages, industrial doors, barriers and escalators. These sensors are characterized by industrial quality, reliability and the appropriate certifications. Automated access technology Sensor Partners' wide range of sensors includes an exclusive selection of detection and safety systems specifically designed for applications within access engineering. ![]() The sensor detects everything that passes between the sensor and the taught background. These sensors only detect objects within a defined zone. Photoelectric sensors with background suppression Photoelectric sensors with a background suppression function as a photoelectric sensor with diffuse proximity or reflex barriers, with an additional function. ![]()
