Product Description

The Keyence FS-V33 is a high-performance digital fiber optic amplifier designed for precise detection in industrial automation applications. Equipped with a red 4-element LED light source emitting at 640 nm, it offers selectable response times ranging from 33 µs (High Speed) to 16 ms (Mega Turbo), accommodating various detection needs. The amplifier features dual NPN open-collector outputs with a maximum control output of 100 mA, and supports up to 16 expansion units, allowing for scalable system configurations. Its compact design, measuring 30.3 mm (H) x 9.8 mm (W) x 71.8 mm (D), ensures easy integration into tight spaces. The FS-V33 is housed in a durable polycarbonate case and is engineered to withstand environmental challenges, offering protection against reversed polarity, overcurrent, and surge conditions. Its robust design ensures reliable performance in demanding industrial settings.​
