The LR12XBN04DPCW1-E2 proximity sensor, developed by Shanghai Wujiu, is a non-contact detection device specifically engineered for industrial automation applications. Utilizing electromagnetic induction technology, this sensor delivers consistent object position detection capabilities in demanding industrial environments. Its cylindrical metal housing features specialized anti-corrosion treatment, making it suitable for diverse applications including mechanical manufacturing, material handling systems, and equipment assembly lines.
With an effective sensing range of 12mm, this device operates on a wide DC voltage input of 10-30V, ensuring compatibility with most industrial control systems. The NPN normally open configuration with three-wire connection supports load currents up to 200mA, meeting the driving requirements of common actuators. Integrated reverse polarity protection and short-circuit prevention circuits enhance operational reliability.
Equipped with temperature compensation circuitry, the sensor maintains consistent detection accuracy across an operational temperature range of -25℃ to +70℃. The fully sealed construction meets IP67 protection standards, effectively resisting oil contamination, dust ingress, and temporary water immersion. The brass nickel-plated housing incorporates an anti-interference shielding ring around the detection surface, ensuring accurate performance even when installed near metallic structures.
This model is particularly suitable for metal workpiece presence detection, moving component position control, and equipment safety interlocking in automated systems. Its rapid response capability supports detection frequencies up to 1000Hz, making it ideal for high-speed production lines. For optimal performance, installation should maintain axial alignment with detected objects while maintaining lateral clearance of at least three times the sensing distance to minimize adjacent interference.
（注意事项说明）
建议定期使用干燥软布清洁传感器表面，避免使用腐蚀性清洁剂。在强电磁干扰环境中使用时，推荐采用屏蔽电缆并确保良好接地。设备安装后应进行功能性测试，通过观察输出指示灯验证检测有效性。长期存放建议保持原包装于阴凉干燥环境，相对湿度不超过85%。
