Product Description

he Keyence FS-N12P is a compact and efficient digital fiber optic amplifier designed for integration into industrial automation systems. As an expansion unit, it connects seamlessly with other FS-N series amplifiers, allowing for scalable detection solutions. Equipped with a red 4-element LED light source, the FS-N12P offers rapid response times across multiple modes, including HIGH SPEED (50 µs), FINE (250 µs), TURBO (500 µs), SUPER (1 ms), ULTRA (4 ms), and MEGA (16 ms). It features a PNP open collector output capable of handling up to 100 mA, with a residual voltage of 1 V or less. The amplifier operates within a power supply range of 12 to 24 VDC and is housed in a durable polycarbonate case, ensuring reliable performance in various industrial environments.​
