Product Description

The Keyence EV-118USO is a specialized, unshielded M18 inductive proximity sensor designed for precise detection of ferrous metals in industrial automation applications. It features a 15 mm detection range with a ±10% tolerance and operates with a 2-wire configuration, making it suitable for environments where space and wiring simplicity are critical. The sensor offers a switching capacity of 5 to 200 mA and includes built-in protection circuits against reverse polarity, short circuits, and surge voltage. With an IP67 enclosure rating, it ensures reliable performance in harsh conditions, and its nickel-plated brass housing provides durability and resistance to corrosion.​
