英文介绍 (English Description)
The LJ12A3-4-J/EZ is an inductive proximity sensor with M12 cylindrical housing, designed for industrial automation applications. This AC two-wire normally open (NO) sensor detects metal targets within 4mm range without physical contact. Its nickel-plated brass construction ensures durability in harsh environments, while the compact 12mm diameter facilitates installation in confined spaces. 1322
Operating at 90-250V AC, this sensor features fast response time (2.5ms) and built-in protection circuits. The non-contact detection principle eliminates mechanical wear, achieving over 2 million operation cycles. Standard 1.2m cable (extendable) and -25°C to +70°C operating temperature range make it suitable for diverse industrial scenarios including CNC machines, conveyor systems and material handling equipment. 1119
The sensor s IP67-rated enclosure provides reliable performance in dusty or humid conditions. Its threaded mounting design allows flexible integration with standard M12 fittings. When metal objects enter the detection zone, the normally open circuit closes to output signals, enabling precise position monitoring and object counting in automated processes. 815
Ideal for metal detection tasks, this sensor simplifies control system wiring with direct AC line connection. Typical applications include machine tool positioning, automated assembly lines, packaging machinery and safety interlock systems. The product s robust construction and stable performance meet the demands of continuous industrial operation. 16
