Capacitive Proximity Sensor

Capacitive Proximity Sensor is a non-contact sensing solution to metallic as well as non-metallic objects. With adjustable sensitivity, almost any medium can be detected with desired reliability. The primary functional element of capacitive proximity switch is high frequency oscillator with floating electrode in the transistor base circuit. In non-activated state, noise field exists in region of base electrode, which represents active area of proximity switch. When medium appears in active area, oscillations begin.
