Product Description

The Keyence FS-V12 is a compact and versatile digital fiber optic amplifier designed for precise detection in industrial automation applications. It features a red LED light source and offers selectable response times of 250 µs (FINE), 500 µs (TURBO), and 1 ms (SUPER TURBO), accommodating various detection needs. The amplifier includes a shift function with a range of ±1,999 and supports multiple timer modes, including ON-delay (40 ms), OFF-delay (10 ms), and a timer OFF mode, all switch-selectable. Its NPN open-collector output can handle up to 100 mA with a residual voltage of 1 V max. The FS-V12 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.
