It detects metal objects within an 8mm range without physical contact, making it ideal for position sensing in automation systems, CNC machines, and robotics. Its non-contact detection ensures long life and reliable switching in industrial environments.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003eInductive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensing Distance\u003c\/td\u003e\n\u003ctd\u003e8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eNPN Normally Open (NO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e6-36V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Output Current\u003c\/td\u003e\n\u003ctd\u003e200mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitching Frequency\u003c\/td\u003e\n\u003ctd\u003e500 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing Material\u003c\/td\u003e\n\u003ctd\u003eNickel-plated brass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Size\u003c\/td\u003e\n\u003ctd\u003eM18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLimit switch for 3D printers or CNC machines\u003c\/li\u003e\n\u003cli\u003eObject detection on conveyor belts\u003c\/li\u003e\n\u003cli\u003eRobot endstop for precision movement\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-industrial-voice-safety-interlock\"\u003eIndustrial machine safety interlock\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis sensor works with any microcontroller or PLC accepting NPN signals, including Arduino, Raspberry Pi, and ESP32. Its 6-36V operating range suits industrial power supplies, and the NPN output can directly interface with 5V or 3.3V logic using a pull-up resistor. Commonly paired with motor drivers and relay modules for automated control.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect brown wire to positive supply (6-36V DC), blue to ground, and black to the signal input. For microcontroller use, add a 10kΩ pull-up resistor from the black wire to VCC to ensure a clean high signal; the output sinks to ground when a metal object is detected.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, wire the sensor to an external 12V supply (brown to 12V, blue to GND), and connect the black signal wire to an Arduino digital pin via a 10kΩ pull-up resistor to Arduino’s 5V pin. The output will be HIGH when no metal is detected and LOW when triggered.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat is the maximum switching speed?\u003c\/summary\u003e\u003cp\u003eThe sensor has a switching frequency of up to 500 Hz, enabling 500 detections per second. It is suitable for most automation tasks but not for high-speed counting applications beyond this rate.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan it detect plastic or wood?\u003c\/summary\u003e\u003cp\u003eNo, this inductive sensor only detects metal objects. For non-metallic materials, a capacitive proximity sensor is required.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
