LJC18A3 Series Cylindrical Capacitive Proximity Switch - Durable Industrial Solution
The LJC18A3 series is a cylindrical capacitive proximity switch designed for demanding industrial environments. Utilizing capacitive sensing technology, it provides reliable non-contact detection for both metallic and non-metallic objects, with adjustable sensing distances to accommodate diverse installation requirements.
Constructed with high-grade stainless steel housing and enhanced surface treatment, this series offers exceptional resistance to corrosion, mechanical wear, and chemical exposure. With an IP67 protection rating, it operates reliably in challenging conditions such as humidity, dust, or vibration-prone areas. The extended temperature range (-25℃ to +70℃) ensures stable performance in extreme environments, including refrigeration facilities and high-temperature workshops. Advanced anti-interference circuitry minimizes false triggering caused by electromagnetic noise from nearby equipment.
Featuring industry-standard threaded housing, the LJC18A3 allows flexible mounting on automated production lines, conveyor systems, or robotic arms. It supports both NPN and PNP output configurations with built-in short-circuit protection, enabling seamless integration with PLCs and industrial control systems. The contactless design eliminates mechanical wear, significantly extending service life while reducing downtime and maintenance expenses.
Key applications encompass liquid level detection in beverage filling systems, material presence monitoring in packaging machinery, component positioning for automotive assembly, and object recognition in logistics sorting systems. Its compact form factor and consistent signal output characteristics deliver an energy-efficient solution for industrial automation processes, enhancing operational efficiency across multiple sectors.
