LJC12A3-A-Z/BXBY/AX/AY Capacitive Proximity Switch Introduction (English Version)
The LJC12A3-A-Z/BXBY/AX/AY series capacitive proximity switches are non-contact detection devices based on capacitive sensing technology, designed for industrial automation, machinery equipment, and material handling systems. Available in both Normally Open (NO) and Normally Closed (NC) contact configurations, these switches provide flexible solutions for detecting metallic and non-metallic objects.
Utilizing dielectric constant variation detection principle, the switches offer adjustable sensing distances to accommodate objects of various sizes and materials. The engineering plastic housing ensures impact resistance and corrosion protection, maintaining stable operation within -25℃ to +70℃ temperature range. With a compact 12mm diameter design, the product supports multiple sensing orientations including axial (AX), radial (AY), and multi-directional (BXBY) configurations for versatile installation in confined spaces.
The Normally Open (NO) model maintains an open circuit state until detecting a target object, ideal for material presence verification and production line counting. The Normally Closed (NC) version operates inversely, suitable for safety monitoring and material shortage alert systems. Featuring 10-30V DC wide voltage input compatibility, the switches incorporate short-circuit protection and reverse polarity protection for enhanced reliability in demanding environments.
Applications include material detection in packaging machinery, workpiece positioning in automated production lines, and medium identification in liquid level control systems. The optimized anti-interference design minimizes electromagnetic disturbances, while IP67 protection rating ensures durability in dusty or oily industrial settings. An integrated LED status indicator facilitates on-site commissioning and maintenance operations.
Key advantages include stable performance across material variations, simplified installation through multiple mounting options, and adaptive detection capability for diverse industrial scenarios. This product series demonstrates balanced sensitivity and environmental adaptability, providing cost-effective solutions for object detection requirements in modern industrial control systems.
