Product Introduction of LJ12A3-2(4)-Z/AY Proximity Sensor (English Version)
The LJ12A3-2(4)-Z/AY is an industrial-grade inductive proximity switch employing non-contact detection technology. Designed for position sensing and object recognition in automation systems, mechanical equipment, and material handling applications, this device utilizes electromagnetic induction principles to achieve reliable detection of metallic targets with rapid response and strong environmental adaptability.
Featuring a hybrid construction of engineering plastic and metal housing with surface treatment, the sensor operates stably within a temperature range of -25℃ to +70℃. The cylindrical threaded housing (M12×1 standard thread) enables easy installation and maintenance, offering selectable detection distances of 2mm or 4mm. Equipped with high-sensitivity sensing components, it ensures consistent output signals for ferromagnetic metal detection. The product provides both NPN and PNP output configurations (denoted by Z/AY suffix) to accommodate mainstream controller interface requirements.
In practical applications, the LJ12A3-2(4)-Z/AY excels in machine tool positioning, production line material detection, and packaging equipment motion control. Its protective structure withstands common industrial environmental challenges including oil contamination and dust particles. The integrated LED status indicator facilitates on-site debugging and operational monitoring. Enhanced circuit design incorporates reverse polarity protection and overload protection for improved system safety.
Usage recommendations: Ensure parallel alignment between the sensing face and target object during installation, avoiding strong electromagnetic interference environments. Regular cleaning of the sensor surface helps maintain optimal performance. Professional technical support is advised for system integration.
