IFM IFM204 Inductive Sensor – IFKC007-ASKG/V4A/US-104
The IFM204 is a robust, high-durability inductive proximity sensor designed for mobile and harsh industrial environments. Featuring a threaded M12 housing, increased sensing range of 7 mm, and a configurable PNP/NPN normally open output, it delivers precise non-contact object detection. The IFM204 offers enhanced EMC protection, withstands extreme temperatures (–40 to +85 °C), and includes IP69K sealing for full washdown and outdoor use. Built with gold-plated M12 contacts, shock-rated to 100 g, and certified to ECE R10 automotive standards, it is ideal for rugged automation and mobile machinery applications.
