Product Description

The Keyence EZ-12M is a shielded, M12-threaded inductive proximity sensor designed for precise detection of ferrous metals in industrial automation applications. With a compact cylindrical form factor, it offers a 2.5 mm detection range and a response frequency of 600 Hz, ensuring swift and accurate sensing. The sensor features an NPN open collector output capable of handling up to 100 mA, making it suitable for interfacing with most control systems. Housed in a nickel-plated brass casing, it provides durability and resistance to environmental factors. Its IP67 rating ensures protection against dust and water ingress, while its wide operating temperature range of -25°C to +80°C makes it versatile for use in harsh conditions.​
