The Keyence EV-108UC Main Unit is a compact, unshielded type proximity sensor engineered for reliable detection of metal targets in demanding industrial environments. Designed with precision and robustness in mind, this M8 model combines fast response, durability, and user-friendly operation to meet the needs of automated production systems.

At the core of its functionality, the EV-108UC offers a detecting distance of 4 mm ±10%, optimized for ferrous metals and adaptable to nonferrous materials with adjusted sensitivity. Its standard target size of 20 × 20 mm ensures consistent detection performance, making it well-suited for a wide variety of applications such as assembly, robotics, and packaging processes. With a response frequency of 800 Hz, the unit excels in fast-paced operations, accurately detecting moving targets without delay.

The sensor is designed as an unshielded, cylindrical M8 unit, which allows for installation flexibility, especially in confined or densely packed machine setups. Despite its compact size, it delivers powerful detection capabilities while maintaining excellent stability across varying environmental conditions. The N.C. (normally closed) operation mode provides dependable switching suitable for control systems that require secure fail-safe design.

Durability is a standout feature of the EV-108UC. Constructed with a stainless steel (SUS304) housing, it provides superior resistance to wear and corrosion, ensuring long service life even in harsh industrial settings. Its IP67 enclosure rating means it is fully protected against dust and can withstand exposure to water, including temporary immersion. The unit can reliably operate in a wide temperature range of -25 to +80 °C, making it adaptable to diverse climates and factory conditions. Furthermore, it is engineered to resist vibration (10 to 55 Hz, 1.5 mm double amplitude) and shock (500 m/s², 3 times in each axis), enabling stable operation in environments with heavy machinery and constant motion.

Electrical performance is equally robust. The EV-108UC supports a power voltage range of 12 to 24 VDC, with low current consumption and a switching capacity of 5–80 mA, ensuring compatibility with a variety of control systems. Integrated protection circuits safeguard the sensor from reverse polarity and surge voltage, enhancing safety and preventing electrical damage. The unit’s residual voltage of 3.6 V max. ensures efficient signal transmission, even when installed with the included 2 m cable.

Weighing only 42 g, the EV-108UC is lightweight yet sturdy, simplifying installation and handling. Each unit is supplied with essential accessories including two nuts, a toothed washer, and an instruction manual, ensuring easy mounting and immediate integration into existing systems.

In summary, the Keyence EV-108UC is a compact, fast, and durable proximity sensor designed for high-performance detection in modern automation environments. With its rugged stainless-steel body, fast response, wide environmental resistance, and built-in protection features, it provides a reliable and long-lasting solution for industries that demand precision and efficiency.
