Product Introduction of HUGONG OMCH Proximity Sensor LJ8A3-2-Z/EX
The HUGONG OMCH series LJ8A3-2-Z/EX is a DC 2-wire normally open inductive proximity switch designed for industrial automation applications, compatible with 12V/24V/36V DC power systems. Featuring a compact cylindrical structure, its housing combines high-strength engineering plastic with metal threaded components, delivering excellent mechanical durability and environmental resistance. Equipped with precision oscillation coils at the sensing end, this non-contact detection device operates on electromagnetic induction principle, achieving a maximum detection distance of 2mm with response time under 1ms, making it suitable for real-time monitoring in high-speed production lines.
The product emphasizes practicality and reliability with built-in overvoltage and reverse polarity protection circuits to minimize operational risks. The oil-resistant coating on the sensing surface and IP67 protection rating ensure stable performance in environments containing dust, oil mist, or light water splashes. Wide-temperature components support operation from -25℃ to +70℃, adapting to challenging conditions in cold storage facilities and high-temperature workshops. The 2-wire connection system simplifies installation, while color-coded red/blue wires and standard M8 threaded mounting interface enable quick integration into mechanical equipment or control systems.
LJ8A3-2-Z/EX proves versatile in machine tool positioning, conveyor belt counting, and automated equipment status monitoring. Typical applications include metal component presence detection in automotive manufacturing, material shortage warning in packaging machinery, and pallet position recognition in logistics sorting systems. The integrated status indicator provides real-time detection feedback for on-site debugging and troubleshooting. Regular cleaning of the sensing surface is recommended to maintain detection accuracy, with installation advised away from strong magnetic interference sources.
