The PRFDACM12-3DN from Autonics is a high-performance long-distance proximity sensor with a sensing range of 3mm, optimized for detecting iron targets sized 12Γ12Γ1mm. Engineered with an M12 sensing diameter and a PTFE-coated SUS303 stainless steel housing, this sensor ensures excellent resistance to corrosion, oil, and harsh environments. It uses a DC 3-wire 10β30VDC power supply and features an NPN control output with up to 100mA load capacity, ensuring compatibility with a wide range of industrial control systems. The current consumption is limited to 20mA, and the residual voltage remains below 2.5V for stable performance. The M12 plug connector simplifies installation and maintenance, especially in modular automation setups.
This sensor supports IP66, IP67, IP67G, and IP68 protection ratings, making it ideal for high-moisture and dusty environments. It is designed to operate in extreme ambient temperatures ranging from -25Β°C to 70Β°C, and its built-in protection circuits guard against reverse polarity, surge, and short-circuit conditions. Additional features such as an orange operation LED, green stability LED, and error indication improve troubleshooting and monitoring during runtime. With a response frequency of 80Hz, the PRFDACM12-3DN is suitable for low to medium-speed automation processes. Click here to view the official Autonics product page.
Maintenance engineers often deploy the Autonics PRFDACM12-3DN in CNC machinery, packaging systems, and small conveyor assemblies where short-range, metal-only detection is required. Its stainless steel construction makes it ideal for washdown zones or production lines exposed to oil and chemicals. The PTFE coating adds further reliability in abrasive environments, such as food processing or metal cutting units. For OEMs designing modular sensor banks, the M12 connector facilitates fast replacement without rewiring. Engineering students and automation trainees find this model useful for understanding long-distance inductive sensing with robust protective features. Its blend of build quality, electrical performance, and environmental protection makes the PRFDACM12-3DN one of the most trusted sensors in its category.
