High-Precision Shielded Proximity Sensor for Industrial Automation
The KEYENCE EZ-8M(5M) is a self-contained three-wire proximity sensor engineered for precise detection of ferrous metals in demanding industrial environments. With a 1.5mm detection range and ±10% accuracy, it ensures reliable object detection even in high-speed applications. Its shielded M8 design minimizes interference, making it ideal for compact machinery and tight spaces. The sensor features an 800Hz response frequency, enabling rapid feedback for real-time automation processes. Built with a stainless steel (SUS303) housing and IP67 rating, it withstands harsh conditions, including dust, moisture, and oil exposure. An integrated LED indicator simplifies status monitoring, while the flexible cable joint reduces strain during installation. This model is optimized for automotive assembly lines, robotics, and material handling systems, where precision and durability are critical.
Advanced Technical Specifications and Robust Performance
Designed for industrial reliability, the EZ-8M(5M) operates on 12–24V DC power with a low current consumption of 13mA, ensuring energy efficiency. Its NPN open collector output supports up to 100mA load, with a residual voltage of ≤1V for stable signal transmission. The sensor maintains ±10% detection consistency across a wide temperature range of -25°C to +80°C, making it suitable for extreme environments. It also withstands vibration (10–55Hz, 1.5mm amplitude) and shock (500m/s²), ensuring long-term performance in high-vibration settings. Accessories include mounting nuts and a toothed washer for secure installation, while the 2m oil-resistant cable simplifies integration. CE and UL certifications validate its compliance with international safety standards, ensuring seamless deployment in global manufacturing facilities.
Versatile Applications in Manufacturing and Quality Control
The EZ-8M(5M) excels in automotive production, detecting metal components on conveyor belts, verifying part presence in press machines, and monitoring robotic arm positions. In electronics assembly, it counts small metal parts with micron-level precision and ensures accurate pick-and-place operations. For packaging industries, the sensor tracks carton alignment and detects metal contaminants in sealed products. Its self-contained amplifier eliminates the need for external controllers, reducing system complexity and costs. Additionally, the sensor’s hysteresis control (≤10% of detection range) prevents false triggers, enhancing process stability. By combining high-speed response with rugged construction, the EZ-8M(5M) delivers optimal performance in industrial automation, machine tooling, and quality inspection systems.
