Wengart M8 Inductive Proximity Sensor Switch, LJ8A3-2-Z/AX, DC 10-30V, NPN NC (Normally Closed), 2mm Detection Distance, 3-Wire Inductive Proximity Switch for 3D Printer, CNC & Industrial Automation

Wengart M8 Inductive Proximity Sensor Switch, LJ8A3-2-Z/AX, DC 10-30V, NPN NC (Normally Closed), 2mm Detection Distance, 3-Wire Inductive Proximity Switch for 3D Printer, CNC & Industrial Automation

• PRECISION METAL DETECTION: Engineered with high-frequency oscillation technology to detect metallic objects within a 2mm range. The M8 threaded body allows for fine-tuned positioning, making it essential for limit switching, positioning control, and automatic counting
• NPN NC LOGIC (NORMALLY CLOSED): Designed for fail-safe operations. In NC mode, the circuit remains closed until a metal object is detected. This is a critical requirement for many industrial safety limiters and specialized 3D printer Z-height sensing
• WIDE VOLTAGE & STABLE OUTPUT: Supports a broad DC 10-30V input range, ensuring compatibility with PLC industrial controllers and most 3D printer mainboards. Delivers a reliable 300mA output with integrated short-circuit and reverse polarity protection
• VERSATILE UPGRADE FOR HOBBYISTS: Beyond factory use, this sensor is a popular choice for 3D printer "Auto-Leveling" upgrades and CNC end-stop limiters. Its compact M8 size fits perfectly into tight mechanical builds where space is at a premium
• DURABLE INDUSTRIAL BUILD: Features an IP67-rated nickel-plated brass shell that resists oil, water, and vibration. The high-flex 3-wire cable ensures long-term reliability even on moving gantry systems. Pro-Tip: Detection distance may vary based on the type of metal (Max 2mm for Iron)
