AC NO 4mm Inductive Proximity Sensor in Nickel-Plated Brass LJ12A3-4-J/EZ

Welcome to our shop! Discover our inductive proximity switch, a high-performance position sensor that operates without direct mechanical contact with moving parts. When a metallic object approaches its sensing surface at the rated distance, it is activated without pressure or sparking, thus controlling DC electrical devices or sending precise control instructions to computer systems (such as PLCs). This proximity switch, also known as a non-contact electronic switching sensor, combines the advantages of limit switches and microswitches with increased sensitivity. It is distinguished by its reliable operation, stability, ultra-fast response, long service life, and excellent resistance to interference. Designed for demanding environments, it is waterproof, shockproof, and corrosion-resistant. Compared to traditional mechanical limit switches, it offers significant advantages in terms of stroke control, positioning accuracy, operating frequency, lifespan, ease of installation and adjustment, and adaptability to harsh conditions. Main applications: widely used in machine tools, metallurgy, chemicals, textiles, and printing. In automatic control systems, it is used for stop, counting, position control, and automatic protection functions. **Detailed Technical Specifications:** **Model:** LJ12A3-4-J/EZ **Detection Distance:** 4mm ± 10% **Adjustment Distance:** 0 - 3.6mm **Delay Distance:** < 10% of the detection distance **Standard Object:** Magnetic metal (distance decreases for non-magnetic metals) **Reference Detection Object:** Iron 15x15x1 mm **Response Frequency:** DC: 0.5 kHz / AC: 25 Hz **Power Supply:** AC 110-220V (range 36-250V) 50/60Hz **Withstand Voltage:** AC 1000V 50/60Hz **Voltage Effect:** ±15% of Nominal voltage* **Consumption current:** NP: < 13mA, D: < 0.8mA, A: < 1.7mA* **Control output:** NP: < 300mA, D: < 200mA, A: < 400mA* **Circuit protection:** A: Overvoltage absorption protection.
