The Keyence FS-N14N is a high-functionality fiber amplifier expansion unit designed to extend the capabilities of the FS-N Series. With its dual-output design and robust performance, the FS-N14N provides a versatile solution for applications requiring fast response, precise control, and stable operation under challenging industrial conditions.

As an expansion unit with dual NPN outputs, the FS-N14N allows for advanced control functionality in automation systems. Each output can drive up to 100 mA when used in stand-alone mode, while multi-unit configurations provide flexible output handling with shared capacity. This makes it highly effective for multi-signal monitoring, part differentiation, and pass/fail detection within a compact design.

The amplifier is engineered for high-speed performance, featuring response modes that can be tailored to application needs. At its fastest setting, the FS-N14N achieves an impressive 50 µs response time, ensuring reliable detection of high-speed moving targets. Other selectable modes (250 µs, 500 µs, 1 ms, 4 ms, and 16 ms) offer optimized performance for stable detection in varied conditions, giving operators precise control over system behavior.

Energy efficiency is another hallmark of the FS-N14N. It offers three power consumption modes: Normal (900 mW), Eco On (800 mW), and Eco Full (470 mW). These modes allow users to minimize energy usage, especially in systems with multiple amplifiers—up to 16 units can be interconnected, with dual-output types counted as two units. This scalability ensures efficiency in large automation setups.

Built for industrial endurance, the FS-N14N operates reliably in ambient light conditions up to 30,000 lux, resisting interference from sunlight or incandescent sources. Its rugged construction withstands shock forces up to 500 m/s², vibration from 10–55 Hz, and temperatures from -20 to +55 °C, ensuring long-term durability in harsh environments. The housing, made from polycarbonate, adds both strength and lightweight handling, with a total weight of about 70 g.

The FS-N14N also integrates interference-prevention technology, with unit capacity scaling from 0 at high-speed mode to 8 (or doubled when set to enhanced mode) at slower settings. This ensures reliable performance in applications where multiple sensors are used in close proximity, preventing crosstalk and signal disruption.

In summary, the Keyence FS-N14N Fiber Amplifier is a high-functionality, dual-output expansion unit that combines speed, efficiency, and durability. With its ultra-fast response options, scalable connectivity, and rugged environmental resistance, it is ideally suited for advanced automation systems where precision, flexibility, and reliability are essential.
