【English Version】
The LJ12A3-4-J/EZ proximity switch is a non-contact detection device specifically designed for industrial automation control. Operating on 220V AC power with two-wire configuration, it features M12 standard threaded housing, making it suitable for object position detection in various industrial applications.
Utilizing electromagnetic induction principle, this switch activates signals through the approach of metal targets without physical contact. The compact cylindrical design with M12×1mm thread allows quick installation. The housing combines corrosion-resistant metal with engineering plastic protection layer, ensuring stable operation within -25℃ to +70℃ temperature range. The open-type (NO) output simplifies control system wiring, instantly delivering conduction signals when objects enter the 4mm effective sensing range.
Ideal for equipment positioning in automated systems, conveyor belt monitoring, and robotic arm control, this product excels in machine tool processing, packaging machinery, and logistics sorting applications requiring fast response. The built-in overload protection and anti-interference shielding effectively reduce false triggering. Vibration-resistant terminals maintain connection reliability in dynamic environments. Installation should maintain parallel alignment between sensing surface and target objects, with adequate safety clearance to prevent mechanical impact.
