Capacitive Proximity Sensor

The Capacitive Proximity Sensor is a non-contact sensor designed to detect both metallic and non-metallic objects such as plastics, glass, wood, water, and grains. It operates by sensing changes in capacitance when an object enters its detection zone. These sensors are widely used in automation systems, material level detection, touch-free switches, and smart machinery. Featuring a rugged, industrial-grade design and reliable switching, capacitive proximity sensors are easy to integrate with PLCs, Arduino, Raspberry Pi, and other control systems.

Key Features:
