Product Description

The Keyence FS-V22 is a compact digital fiber optic amplifier designed for precise detection in industrial automation applications. It features a red LED light source and offers selectable response times ranging from 50 µs (High Speed) to 4 ms (Ultra Turbo), accommodating various detection needs. The amplifier includes a shift function with a range of ±1,999 and supports multiple timer modes, including OFF, OFF-delay, ON-delay, and one-shot timers, with durations from 1 to 500 ms. Its NPN open collector output can handle up to 20 mA with a residual voltage of 1 V max. The FS-V22 operates on a 12 to 24 VDC power supply and offers low power consumption, making it suitable for energy-efficient applications. Housed in a durable polycarbonate case, it 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.​
