The IFM IFS240 is a flush-mountable M12 inductive sensor with a 4 mm increased sensing range. It uses a PNP normally open output and operates from 10 to 30 V DC. Gold-plated contacts and a robust brass housing support reliable industrial operation. The sensor provides a 700 Hz switching frequency and integrated short-circuit and overload protection. Its high environmental protection makes it suitable for demanding factory automation applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The IFS240 provides a nominal sensing range of 4 mm with an actual sensing range of 4 ±10%. Its operating distance is 0...3.24 mm. The increased sensing range allows reliable detection while maintaining a compact M12 form factor. The flush mounting arrangement simplifies installation in metal machine structures. This makes it suitable for general industrial position and presence detection.
The sensor operates at 10...30 V DC with less than 10 mA current consumption. Its PNP normally open output can switch up to 100 mA. A maximum voltage drop of 2.5 V is specified at the switching output. The 700 Hz switching frequency supports high-speed industrial detection. Short-circuit and overload protection improve electrical reliability.
The IFS240 uses an M12 × 1 threaded brass housing with a total length of 60 mm. The housing is white-bronze coated and the sensing face uses PBT. IP65, IP66, IP67, IP68, and IP69K ratings provide strong environmental protection. Gold-plated M12 contacts improve connection reliability. These characteristics make the sensor suitable for industrial, mobile, cooling, and lubricating applications.
