Inductive Proximity Sensor

Chennai-based MRK Engineers offers inductive proximity sensors. These 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 is comprised 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, a damping action results which reduces the amplitude of the oscillator. This amplitude shift is converted to a digital signal by he level detection (ie, a Schmitt trigger), which drives a buffer stage. When the object is removed, the oscillator and the digital is turned to its format state. These are available in DC as well as AC, with various sizes from M8 M80, with various configuration and sensing distance inductive micro box sensor, slot sensor and any other types of sensor can be supplied as per the specific requirement.
