Introduction to LJ3A3-1-Z/EX Proximity Switch
The LJ3A3-1-Z/EX is an inductive proximity sensor designed for non-contact detection of metallic objects. Featuring a compact 3mm cylindrical housing with 1mm sensing range, it operates on 6-36VDC power supply and provides normally open two-wire DC output. Its metal casing offers IP67 protection against dust and water ingress, making it suitable for harsh industrial environments. The sensor utilizes high-frequency oscillation principle - when a metal target enters its electromagnetic field, eddy currents dampen the oscillation to generate switching signal. Typical applications include position control on CNC machines, object counting in assembly lines, and safety interlocking in automated equipment.917
Technical Features and Benefits
This proximity switch delivers high switching frequency exceeding 200Hz with consistent repeat accuracy. Its contactless design eliminates mechanical wear, ensuring over 100,000 operations within -25℃ to +70℃ temperature range. The threaded barrel allows both flush and non-flush mounting configurations. Compared with conventional models, it demonstrates superior immunity to electromagnetic interference with built-in status LED for easy commissioning. The optimized coil design maintains stable performance even with vibration or surface contamination, reducing maintenance requirements in demanding applications. These characteristics make it a reliable solution for industrial automation systems.1620
