Invisible Touch

invisible touch (also known as inductive proximity sensors or proximity switches) are electrical command devices that can replace other mechanical types of switches such as limit switches, microswitches, and many others. They are able to detect metal and aluminum targets or designated positions without contact.

invisible touch can be used for a number of industrial applications including in warehousing and material handling as they are able to check the position of lifting arms. Other applications include usage in heavy machinery such as forklifts, trucks, as well as the monitoring parts of hydraulic machines.

Some of the invisible touch available can operate with no noise, bounce, and reaction, and are able to operate without any sensitivity to vibrations and shock. The invisible touch come with the core components: coils, an oscillator, an output amplifier, as well as a Schmitt trigger. There are different versions of this sensor available, including unshielded (which allows for wider sensing distances) and shielded (with an electromagnetic field that is concentrated at the front).
