The NF-M468 with optical sensors RoHS is a digital optical switch that uses infrared light emitted from an LED optical detector to sense the presence of objects. It is RoHS compliant, meaning that it has been tested to meet environmental and safety standards. The NF-M468 comes with a built-in amplifier, which allows it to detect a wide range of objects, from thick cardboard to assemblies of plastic and other materials. Its adjustable detection range and sensitivity make it suitable for a variety of industrial applications. It is also resistant to shocks, water, dust, and extreme temperatures. The NF-M468 is manufactured by Lipoo, a leading producer in the world of digital optical switches and sensing devices.
