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.
