Inductive Proximity Sensors
R S Electronics offers a range of Inductive Proximity Sensors that provide an excellent means for detecting the presence of a wide range of metallic targets. This detection is accomplished without contacting the target and is mechanically wear free. In principle, an inductive proximity switch comprises of a high frequency oscillator circuit followed by a level detector and a post amplification signal circuit and drives a buffered solid-state output. In effect, when a metallic object is brought within the effective range of the emitted field of the oscillator, the resultant amplitude shift is converted to a digital signal by the level detection (i.e., a Schmitt trigger), which drives a buffer stage, when it is turned to its format state. These sensors are available in DC as well as AC, with various sizes from M8-M80, with various configurations and sensing distances. Inductive micro box sensor, slot sensor and any other type of sensor can be supplied as per the specific requirement.
