It offers both normally open (NO) and normally closed (NC) PNP outputs, making it adaptable for various control and automation tasks. The 8mm sensing range and rugged metal housing ensure reliable performance in industrial environments.\u003c\/p\u003e\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\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\u003eThread Size\u003c\/td\u003e\n\u003ctd\u003eM18 x 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensing Distance\u003c\/td\u003e\n\u003ctd\u003e8mm (shielded)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003ePNP, NO + NC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e10-30 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Load Current\u003c\/td\u003e\n\u003ctd\u003e200 mA\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\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eContactless limit switch for CNC machines\u003c\/li\u003e\n\u003cli\u003eMetal part counter on conveyor belts\u003c\/li\u003e\n\u003cli\u003eLiquid level sensing using metal floats\u003c\/li\u003e\n\u003cli\u003eRPM measurement for rotating shafts with metal targets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks directly with 24V PLC inputs and industrial relay modules. For 5V microcontrollers like Arduino, use a level shifter or a 24V to 5V optocoupler interface. The PNP output sinks current to the positive rail, so pairing with PNP-compatible input modules is essential.\u003c\/p\u003e\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eStandard wire colors: brown for +V, blue for GND, black for NO, white for NC. Ensure the load does not exceed 200mA. A flyback diode is recommended when driving inductive loads like relays. Avoid bending the cable sharply near the sensor body.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\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\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, but you need an external 24V power supply and a level converter since the sensor output is PNP 24V. A common approach is using an optocoupler module to shift the output to 5V logic.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the difference between NO and NC outputs?\u003c\/summary\u003e\u003cp\u003eNO (normally open) output switches on when metal is detected, while NC (normally closed) switches off. This sensor provides both signals simultaneously for flexible control logic.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan it detect aluminum the same as steel?\u003c\/summary\u003e\u003cp\u003eNo, the sensing distance is reduced for non-ferrous metals. For aluminum, expect about 4-5mm. The 8mm rating is for standard mild steel targets.\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.
