The Original New IFM IFM204 is a rugged inductive proximity sensor engineered for high shock and vibration resistance in mobile machines and harsh industrial environments. Featuring E1 type approval by the German Federal Motor Transport Authority (Kraftfahrt‑Bundesamt), it is specifically designed for off‑highway vehicles, construction equipment, and agricultural machinery. With a 7 mm non‑flush sensing range, selectable PNP/NPN output, wide –40°C to +85°C operating temperature range, and IP67 / IP69K protection, this sensor delivers reliable metal object detection under extreme conditions. Core Engineering Highlights:7 mm non‑flush sensing range (real Sr: 7 mm ± 10%) | PNP/NPN selectable output | 10‑36 V DC operating voltage | 300 Hz switching frequency | IP67 / IP69K protection rating | M12 x 1 threaded nickel‑plated brass housing | 70 mm housing length | Gold‑plated M12 connector contacts | –40°C to +85°C operating temperature | E1 type approval (German Federal Motor Transport Authority) | 1,253 years MTTF Key Features: Original New IFM IFM204 sensor Inductive proximity sensor for non‑contact detection of metal objects Non‑flush (unshielded) mounting for extended sensing range 7 mm nominal sensing range with 0‑5.67 mm operating distance PNP/NPN selectable output for flexible integration Normally open (NO) output function 300 Hz switching frequency for reliable detection Nickel‑plated brass housing for durability in harsh environments Gold‑plated M12 connector contacts for reliable signal transmission Increased sensing range for high uptime Reverse polarity, short‑circuit (pulsed), and overload protection Wide 10‑36 V DC operating voltage range for mobile applications Protection rating IP67 and IP69K for high‑pressure washdown and immersion Wide ambient temperature range: –40°C to +85°C E1 type approval by the German Federal Motor Transport Authority High EMC noise immunity for automotive and mobile equipment environments 20 g vibration resistance (10‑3000 Hz) and 100 g shock resistance Continuous shock resistance: 40 g for 6 ms, 4000 shocks per axis Correction factors: steel 1.0, stainless steel 0.7, brass 0.5, aluminium 0.4, copper 0.3 Applications: Position sensing in mobile machines (construction, agricultural, forestry equipment) End‑position detection on hydraulic cylinders and actuators Part presence verification in off‑highway vehicles Conveyor and material handling systems in harsh environments High‑vibration applications requiring E1 type approval Outdoor and extreme temperature applications (–40°C to +85°C) Technical Specifications: Attribute Specification Catalog Number IFM204 Order No. IFKC007-ASKG/M/US-104-DRS Product Type Inductive proximity sensor Housing Threaded type, M12 x 1 Housing Length 70 mm Housing Material Brass, nickel‑plated Sensing Face Material PBT Mounting Non‑flush mountable Sensing Range 7 mm Real Sensing Range Sr 7 mm ± 10 % Operating Distance 0‑5.67 mm Increased Sensing Range Yes Electrical Design PNP/NPN selectable Output Function Normally open (NO) Operating Voltage 10‑36 V DC Current Consumption < 10 mA (3‑wire operation) Max.
