This M12 cylindrical inductive sensor utilizes a high-frequency electromagnetic field to detect metallic targets with absolute accuracy without physical contact. This non-contact measurement principle eliminates mechanical wear, making it an ideal choice for high-speed counting, limit switching, and position monitoring in automated assembly lines and packaging machinery. With its 2mm sensing range and flush-mount design, the sensor integrates seamlessly into compact mechanical structures while maintaining high switching frequencies. Its robust brass nickel-plated housing and IP67 protection rating ensure consistent performance even in environments characterized by vibration, moisture, and industrial debris.\u003c\/p\u003e\n\u003ch2\u003eCore Technical Advantages\u003c\/h2\u003e\n\u003cp\u003eThis sensor features a PNP normally open (NO) switching output, designed for high-speed integration with PLC input modules. The M12 x 1 threaded cylindrical housing facilitates precise depth adjustment during installation, while the V1 (M12 x 1) 4-pin plug connection enables rapid replacement and reduces downtime during maintenance cycles. The internal circuitry includes short-circuit and reverse polarity protection, shielding the sensor from common electrical installation errors. Its flush-mounting capability allows the sensor to be embedded directly into metal mounting plates without interference, providing a streamlined mechanical profile that resists physical impact from moving machine parts.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eSensing Range (sn)\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2 mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eFlush Mount\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOutput Type\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003ePNP Normally Open (NO)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e10 ... 30 V DC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eSwitching Frequency\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0 ... 1500 Hz\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eHysteresis (H)\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eTyp. 5%\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOperating Current (IL)\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0 ... 200 mA\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eIngress Protection\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP67\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eConnection Type\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eV1 Connector (M12 x 1), 4-pin\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eHousing Material\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBrass, Nickel-Plated\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-25 °C to 70 °C (-13 °F to 158 °F)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e12mm (Diameter) x 40mm (Length)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eApproximate Weight\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e25 g\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eInstallation Guide\u003c\/h2\u003e\n\u003cp\u003eEngineers should install the NBB2-12GM40-E2-V1 using the provided twin nuts to secure the sensor at the desired detection depth. For optimal performance, ensure the sensing face remains clear of heavy metal buildup or iron filings which could cause false triggering. When utilizing the V1 plug connection, tighten the M12 cable connector to the specified torque to maintain the IP67 seal against liquid ingress. Although this is a flush-mount sensor, maintain a minimum clearance equivalent to the sensor's diameter from opposing metallic surfaces to prevent pre-damping of the electromagnetic field. In high-vibration applications, we recommend applying a medium-strength thread-locking compound to the mounting nuts to ensure long-term positional stability.\u003c\/p\u003e\n\u003ch2\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cp\u003eThe NBB2-12GM40-E2-V1 excels in high-duty cycle applications where reliability is the primary engineering constraint. Its 1500 Hz switching frequency allows for precise detection in rapid motion sequences, such as tooth-counting on a gear or high-speed piston monitoring. The nickel-plated brass housing provides a durable barrier against mild corrosive agents and mechanical stress. By eliminating the friction and failure points of mechanical limit switches, this inductive solution reduces the total cost of ownership and significantly extends the service life of the machine’s sensing subsystem. Its compatibility with industry-standard M12 connectivity ensures that it fits into existing infrastructure with zero modification required.\u003c\/p\u003e\n\u003ch2\u003eDelivery \u0026amp; Logistics\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDelivery Time:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3-5 days once payment is finalized.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Carriers:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eShipped via DHL, FEDEX, or UPS.
