M18 Plastic Capacitive Proximity Switch
✨Features
Product Introduction
This Capacitive Proximity Sensor is engineered for versatile, non-contact detection of virtually any material, regardless of conductivity. Unlike inductive sensors that only detect metal, this capacitive model can reliably detect liquids, plastics, glass, wood, and bulk powders. It offers precise sensing ranges of 5mm (Flush) and 8mm (Non-flush), making it an essential component for liquid level control, material presence verification, and counting non-metallic objects on conveyor systems.
Housed in a robust PBT plastic shell with an IP67 protection rating, the sensor is resistant to moisture, dust, and chemical exposure. It operates on a standard 10-30VDC supply with a switching frequency of 200Hz. With versatile NPN/PNP output options and comprehensive circuit protection (short-circuit, reverse polarity, surge), this sensor provides a reliable and flexible solution for complex automation challenges where target materials vary.
