  • Magnetic proximity sensor | 12-24VDC | 10mm | PNP | NO | M12 | flush-mounted | nickel-plated brass | IP67

    Code: ES-NJK-5002A

    Non-contact solution for detecting metal and magnetic objects in industry and automation. The sensor ensures fast response, long service life, and stable operation even in demanding conditions (dust, moisture, oil). The compact M12 housing allows easy integration into existing systems, while the PNP NO output enables simple connection to PLCs, relays, or controllers.
