The Keyence EZ-8M is a shielded-type proximity sensor designed for compact yet highly reliable detection of ferrous metals in industrial environments. With its M8 cylindrical body, this sensor is particularly well-suited for installation in tight or restricted spaces, while its shielded design minimizes the influence of surrounding objects, ensuring stable and consistent detection.

The EZ-8M provides a detecting distance of 1.5 mm ±10%, optimized for precision measurement of metal targets. Its standard target size of 10 × 10 mm (iron, t=1 mm) ensures accuracy, making it an excellent choice for applications requiring short-range detection such as part positioning, machine monitoring, and component verification. Coupled with its high response frequency of 800 Hz, the sensor reliably captures fast-moving objects, maintaining accuracy in high-speed automation processes.

Flexibility is a notable strength of the EZ-8M. It supports both normally open (N.O.) and normally closed (N.C.) operation modes, allowing users to adapt the sensor’s output to match diverse system requirements. Its NPN open collector output (100 mA max. at 40 V) ensures reliable control signal transmission, while a residual voltage of just 1 V guarantees efficient and low-loss operation. This makes the sensor easy to integrate into existing PLCs, controllers, or relay-based systems.

Engineered for durability, the EZ-8M is constructed from SUS303 stainless steel, providing robust resistance to wear and corrosion. The IP67 enclosure rating ensures complete protection against dust and resistance to water exposure, allowing the sensor to function reliably even in environments with heavy moisture or contaminants. Its operational range extends from -25 to +80 °C, enabling it to withstand extreme temperatures typically found in industrial environments. Additionally, the unit offers vibration resistance (10 to 55 Hz, double amplitude 1.5 mm) and shock resistance (500 m/s², 3 times in each axis), making it suitable for use in production lines and machinery exposed to constant movement and impact.

The sensor is lightweight at approximately 50 g, yet its construction ensures durability and stability. Each unit is supplied with two screw nuts and one toothed washer, simplifying installation and ensuring secure mounting. The 2 m cable length provides installation flexibility, while the low current consumption of 13 mA or less contributes to energy efficiency.

In summary, the Keyence EZ-8M is a compact, precise, and durable proximity sensor designed for modern automation systems. Its short detection range, high-speed response, shielded construction, and robust environmental resistance make it an ideal solution for industries requiring precise detection in space-constrained and challenging environments. Whether used in assembly lines, robotics, or equipment monitoring, the EZ-8M provides consistent reliability and long-lasting performance.
