Baumer IFRD 18N17T3/S14 Proximity Sensor

The IFRD 18N17T3/S14: 10150450 by Baumer is designed for robust performance in demanding automation environments. It features a nominal sensing distance of 6 mm with quasi-flush mounting, making it perfect for installations where precise proximity detection is required without metal interference. Powered by a 10–30 VDC voltage supply, this NPN make function (NO) sensor supports fast detection cycles with a switching frequency of 100 Hz. It draws only 14 mA of current at no load, ensuring efficient energy use in 24/7 operational setups. The output current rating is 100 mA, with a minimal voltage drop under 2 VDC, which maintains strong signal integrity. Its cylindrical threaded design, with a housing diameter of 18 mm and length of 60 mm, ensures a secure fit and compatibility with standard machine cutouts. The sensor is enclosed in stainless steel 1.4404 (V4A), including the sensing face, offering outstanding corrosion resistance and mechanical durability.

Engineered for longevity, the IFRD 18N17T3/S14 offers static pressure resistance up to 20 bar and a wide operating temperature range of -25°C to +100°C. The sensor’s IP69K protection rating ensures complete protection against water ingress during high-pressure washdowns, making it ideal for food-grade applications or dusty, wet production lines. With its standard M12 connector, installation is fast and secure, minimizing wiring effort and reducing downtime during replacements. Maintenance engineers rely on this sensor for its consistent hysteresis (2–20% of Sr), low noise sensitivity, and long-term operational stability.

The Baumer IFRD 18N17T3/S14 is widely used in conveyor automation, robotic positioning, packaging systems, and metal processing units. In automotive assembly, it verifies component presence during line operations. In food and beverage plants, the stainless steel build withstands cleaning chemicals and ensures hygiene compliance. Machine builders integrate this model into OEM designs for its compact footprint, while technicians appreciate its reliability under extreme mechanical or thermal stress. For engineering students and junior maintenance professionals, this sensor is a reliable benchmark for studying real-world proximity sensing in automation, bridging the gap between textbook theory and industry application.
