Product Introduction (English)

The LJ18A3-5-J/EX proximity switch is an inductive non-contact position sensor designed for industrial automation. It operates based on electromagnetic induction to detect metal objects without physical contact, ensuring fast response and long service life. The device features a robust metal housing with anti-vibration design and IP67 protection, suitable for harsh environments such as humidity, dust, or oil exposure. Its built-in LED indicator provides real-time operational status monitoring. 14

Key Features

With a detection range of 5mm, this sensor offers high sensitivity and stability for rapid-moving targets. It supports a two-wire DC normally open (NO) configuration, compatible with PLCs and control systems. The housing is made of brass or nickel-copper alloy, available in flush (embedded) or non-flush mounting styles. The flush version allows installation level with metal surfaces, while the non-flush type requires detection space. Additional protections include surge suppression and reverse polarity safeguards. 715

Technical Specifications

Operating voltage ranges from 10-30V DC with 200mA output current. The cylindrical body measures 18mm in diameter (M18×1 thread) and 50mm in length. It functions reliably within -25°C to 150°C, ideal for extreme conditions. The sensor’s short signal delay and high repeatability make it suitable for precision applications like machine tool positioning or conveyor belt monitoring in industries like steel manufacturing or automotive assembly. 422

Applications

This sensor is widely used in metal detection, automated production lines, and safety systems across sectors such as mining, chemical processing, and energy. Typical use cases include replacing mechanical limit switches in CNC machines or integrating into material handling systems for object counting. Its shock-resistant design performs well in heavy machinery and construction equipment, ensuring durability under continuous vibration. 227
