The Keyence FS2-62 Fiber Amplifier (Cable Type, NPN) is a highly versatile and durable sensor designed for industrial applications that require precise, stable, and long-distance fiber-optic detection. Engineered with advanced features, this unit ensures reliable operation even in demanding factory environments.

At the core of the FS2-62 is its trimmer-based sensitivity adjustment, offering ultra-long detecting distance capabilities. The 8-turn trimmer allows fine-tuned sensitivity control, enabling the sensor to adapt to a wide range of detection targets and conditions. Paired with a red LED light source, the amplifier delivers consistent and accurate detection performance across varying applications.

One of the key highlights is its fast response time of 500 µs, which makes it ideal for high-speed processes where quick and accurate detection is crucial. The unit supports LIGHT-ON/DARK-ON switch-selectable modes, providing flexibility to match specific system requirements. To enhance usability, the FS2-62 includes clear visual indicators: a red LED for output status and a green LED for stable operation monitoring, ensuring operators can quickly assess system conditions.

The amplifier integrates a built-in timer function, allowing users to select ON-delay, OFF-delay, or Timer OFF modes. This ensures optimized signal control and reduces false detections in dynamic environments. Additionally, the buzzer mode can be configured to activate under different conditions—whether during control output ON, alarm output ON, or turned OFF entirely—providing both visual and audible feedback for enhanced monitoring.

In terms of electrical performance, the FS2-62 features NPN open-collector outputs, with a maximum control output of 100 mA at 40 V and a stability output of 50 mA at 40 V. Protection circuits, including reverse polarity, overcurrent, and surge absorbers, safeguard both the sensor and connected equipment from electrical hazards, increasing long-term reliability.

Designed for tough environments, the FS2-62 demonstrates excellent environmental resistance. It withstands ambient light levels of up to 20,000 lux under sunlight and 10,000 lux from incandescent lamps, maintaining stable detection even under challenging lighting conditions. Its operating temperature range of -10 to +55 °C and humidity tolerance of 35 to 85 % RH make it suitable for diverse applications. The unit is further reinforced with vibration resistance (10 to 55 Hz, 2 hours in all axes) and shock resistance (500 m/s², 3 times per axis), ensuring reliable performance in heavy-duty industrial setups.

Constructed with a durable polycarbonate housing and weighing approximately 61 grams, the FS2-62 combines lightweight design with robustness. This balance makes it easy to integrate into existing systems while withstanding the rigors of industrial environments.

Overall, the Keyence FS2-62 Fiber Amplifier stands out as a dependable, high-performance solution for applications requiring long-range detection, high-speed response, and durability under harsh conditions, making it a valuable component in automation and process control systems.
