Product Description

The Keyence EV-112U is a non-shielded, M12 inductive proximity sensor designed for precise detection of ferrous metals in industrial automation applications. With a detecting distance of 8 mm ±10%, it offers reliable performance in environments with limited space. Operating on a 12 to 24 VDC power supply, the sensor features a two-wire self-contained amplifier, simplifying installation and reducing wiring complexity. Its robust construction, with an IP67 enclosure rating, ensures durability in harsh conditions, withstanding ambient temperatures from -25°C to +80°C and relative humidity levels from 35% to 95% (non-condensing). The EV-112U is equipped with protection circuits against reversed polarity, short-circuit, and surge voltage, making it suitable for various industrial control systems.​
