Product Overview
The Autonics CR18-8DN is a capacitive proximity sensor designed for non-contact detection in industrial automation. It reliably identifies objects with varying dielectric constants, including metals, liquids, and plastics, thanks to its adjustable sensitivity via a built-in potentiometer. The cylindrical housing (M18×1 threaded) ensures easy mounting, while IP66 protection and an operating temperature range of -25℃ to 70℃ guarantee durability in harsh environments.919
Key Features
Operating on capacitive sensing technology, the CR18-8DN triggers signals by detecting changes in dielectric properties between the target and sensor. It offers an 8mm sensing range (under standard conditions), 50Hz response frequency, and supports 10-30VDC power input with low current consumption (<15mA). The 3-wire NPN output includes an operation indicator for real-time status monitoring. Reinforced cable construction enhances flexibility and service life, while integrated overvoltage and reverse polarity protection ensures stable performance.611
Applications
Ideal for material presence checks, liquid level control, and position sensing, this sensor is widely used in packaging machines, food processing equipment, and electronic assembly lines. Its non-mechanical design reduces maintenance needs and improves operational efficiency compared to traditional switches.1016
