The Keyence EV-118USO is a specially ordered proximity sensor designed for demanding industrial applications that require precise and reliable metal detection. Classified under the EV-118U series, this model features a non-shielded M18 cylindrical design, offering both robustness and enhanced detection capabilities for a wide range of automation environments. With a 15 mm detecting distance, the EV-118USO provides extended reach beyond typical M18 proximity sensors, allowing greater installation flexibility without sacrificing accuracy.

Constructed from nickel-plated brass, the sensor body delivers superior mechanical strength and corrosion resistance. This makes it ideal for harsh factory floors where exposure to vibration, dust, oil, or temperature fluctuations is common. Its IP67 enclosure rating ensures protection against dust ingress and temporary water immersion, which further extends the sensor’s lifespan and reliability in environments such as automotive assembly lines, packaging facilities, or robotic equipment.

The EV-118USO stands out with its 15 mm detection distance, enabling operators to install the sensor at safer or more convenient positions while still maintaining dependable detection accuracy. This performance is coupled with a tolerance of ±10%, which ensures stable operation across varying conditions. The sensor is optimized for detecting ferrous metals, though it can also function with certain non-ferrous materials depending on application-specific characteristics.

Performance is further reinforced by its high response frequency of 350 Hz, allowing the device to track and respond to fast-moving targets with exceptional precision. This capability makes the EV-118USO suitable for applications involving conveyor systems, rotational machinery, or high-speed production lines where quick and accurate feedback is critical.

To ensure safety and dependability, the EV-118USO is equipped with built-in protection circuits against reverse polarity, short-circuiting, and surge voltages. These features protect not only the sensor itself but also the downstream control systems, ensuring long-term operational stability and minimizing downtime due to electrical failures. The sensor operates on a 12 to 24 VDC supply with low current consumption and supports a control output range of 5 to 200 mA, making it compatible with a broad range of industrial controllers and PLC systems.

Environmental adaptability is another strength of the EV-118USO. The sensor functions reliably within a wide ambient temperature range of -25 to +80 °C, with stable detecting characteristics maintained even across significant thermal variations. Additionally, its relative humidity tolerance of 35 to 95% RH ensures continued performance in challenging conditions where condensation or humidity shifts may otherwise impair sensor reliability.

In summary, the Keyence EV-118USO proximity sensor combines durable construction, long detection range, high-speed response, and advanced protection features to deliver outstanding performance in industrial automation. This specially ordered model provides the precision and ruggedness necessary for continuous operation in environments that demand both safety and reliability.
