IFM IF0311 Inductive Proximity Sensor
Technical Specifications & Features
The IFM IF0311 (shortcode: IFK2004-BAROA/SL/LS-100AK) is a specialized inductive proximity sensor featuring an increased sensing range in a compact form factor. Built into a robust cylindrical threaded M12 x 1 metal barrel housing made of white bronze-coated brass with a total length of 62 mm, it utilizes a flush mountable installation design. It provides a rated sensing range of 4 mm, a real sensing range ($Sr$) of 4 mm $\pm$ 10%, and an operating distance of 0 to 3.25 mm. Material correction factors include mild steel = 1, stainless steel approx. 0.7, brass approx. 0.4, aluminium approx. 0.3, and copper approx. 0.2.
Key Operational Benefits & Electrical Data
-
Electrical Ratings: Operates on a versatile 2-wire AC/DC architecture with a wide operating voltage range of 20 to 140 V AC / 10 to 140 V DC, a minimum load current of 5 mA, a maximum leakage current of 0.8 mA, and a permanent switching output current rating of 200 mA.
-
Switching Performance: Features a normally open (NO) output function with a maximum voltage drop of 5 V, a switching frequency of 200 Hz (DC) or 25 Hz (AC), a hysteresis of 3 to 15% of $Sr$, and a switch-point drift of -10 to 10% of $Sr$.
-
Environmental & Mechanical Protection: Rated to IP67 for dependable dust and moisture protection in standard and demanding industrial spaces. It operates efficiently within an ambient temperature range of -25 °C to 70 °C and includes a 3-pin micro connector interface.
