CAPACITIVE PROXIMITY SWITCHES

India’s ONLY manufacturer of ISI marked quality Capacitive Proximity Switches Limit Switches has another range of high Capacitive Proximity Switches. Capacitive Proximity Switches serves as a contactless sensors for positioning, monitoring and detecting all types of material. Capacitive Proximity Switch consists of an Oscillator, a Rectifier and an Amplifier. The capacitance between the sensing surface and mass increases when an object approaches active surface. When the capacitance value exceeds the preset level, oscillator generates AC signals. The Rectifier section converts this AC signal into DC and Amplifier amplifies this signal to drive a relay or a circuit.
