High-Precision Inductive Proximity Sensor for Industrial Automation
The KEYENCE EV-108UC is a compact, unshielded inductive proximity sensor designed for precise object detection in industrial environments. With a 4mm sensing range and 800Hz response frequency, it delivers rapid and reliable detection of ferrous metals, making it ideal for high-speed production lines. The sensor features a robust SUS304 stainless steel housing with IP67 protection, ensuring resistance to dust, water, and oil contamination . Its M8 threaded design allows easy integration into machinery, while the built-in LED indicator provides real-time status monitoring. Equipped with reverse polarity and surge voltage protection, the EV-108UC ensures long-term stability even in harsh conditions. Compatible with 12-24V DC power supplies, it offers a switching capacity of 5-80mA, making it suitable for a wide range of automation applications, from conveyor systems to robotic arms.
Enhanced Performance in Demanding Environments
Engineered for durability, the EV-108UC excels in extreme temperatures (-25°C to +80°C) and high-vibration settings, maintaining ±10% detection accuracy across its operational range . Its unshielded design allows flush mounting in metal surfaces without compromising sensitivity, optimizing space in crowded machinery. The sensor’s compact size (M8 x 30mm) and flexible cable guard enable seamless integration into tight spaces, while the fluoropolymer resin-coated threads resist welding spatter and corrosion. With CE certification and compliance with international standards, it meets rigorous safety requirements for automotive, electronics, and food processing industries. The EV-108UC’s high-speed detection capabilities reduce downtime by minimizing errors in fast-paced assembly lines, ensuring efficient production and quality control.
Reliable Solutions for Advanced Automation
The EV-108UC combines precision engineering with user-friendly features to simplify installation and maintenance. Its two-wire design eliminates the need for complex wiring, while the visible output indicator ensures quick troubleshooting. The sensor’s robust construction, including a shock-resistant borosilicate glass lens and acid-resistant neoprene gaskets, guarantees longevity in corrosive environments. KEYENCE’s factory-authorized distribution network ensures access to genuine spare parts and technical support, reducing operational disruptions. Whether used in automotive manufacturing for part positioning or in packaging for product counting, the EV-108UC delivers consistent performance, enhancing productivity and reducing costs. Its compatibility with PLC systems and modular design make it a versatile choice for smart factory initiatives, supporting Industry 4.0 integration.
