Description: 1. LJ12A3-4-Z/BX is an NPN 24V approach sensor, also known as an inductive proximity switch. It uses an electromagnetic field to detect the presence or absence of ferrous metal objects within its sensing range. 2. Features: This sensor offers a detection range from 5mm to 30mm and a switching frequency up to 1kHz. It is designed for harsh environments with IP67 protection against water and dust intrusion, making it suitable for outdoor use. 3. Applications: Common applications include detecting vehicles or objects approaching in access control systems, parking sensors, industrial automation, and material handling systems. 4. Electrical Characteristics: The sensor operates on a 24V DC supply voltage with a maximum current consumption of 15mA at 24V. It has a switching resistance of less than 1 ohm and can handle inductive loads up to 10J. 5. Installation: The LJ12A3-4-Z/BX is easy to install with wiring terminals provided for quick connection to power, signal, and ground. It requir
