Available. The Keyence FS2-65 is a high-speed response fiber amplifier designed for precise light detection in industrial automation applications. Utilizing a red LED light source, it offers an 8-turn trimmer for sensitivity adjustment, ensuring accurate and reliable performance. With a rapid response time of 50 µs, the FS2-65 is suitable for applications requiring swift detection and processing. The device operates in both LIGHT-ON and DARK-ON modes, selectable via a switch, providing flexibility to meet various operational requirements. Indicator lamps include a red LED for output and a green LED for stable operation, facilitating easy monitoring of the system's status. The timer function offers ON-delay and OFF-delay settings of 40 ms each, with an option to disable the timer, allowing customization based on specific application needs. The FS2-65 features NPN open-collector outputs, with a control output capable of handling up to 100 mA (40 V max.) and a residual voltage of 1 V max., and a stability output handling up to 50 mA (40 V max.) with a residual voltage of 1 V max. Protection circuits include reversed polarity protection, overcurrent protection, and surge absorption, ensuring durability and reliability in demanding environments. The device operates within a power supply voltage range of 12 to 24 VDC ±10%, with a current consumption of 35 mA or less. It is designed to withstand ambient light conditions up to 10,000 lux from incandescent lamps and 20,000 lux from sunlight, making it suitable for various industrial settings. The operating temperature range is -10 to +55 °C (14 to 131 °F), and it can handle relative humidity levels between 35% and 85% RH without condensation. The FS2-65 is constructed with a polycarbonate housing, providing durability and resistance to environmental factors. Its compact design weighs approximately 61 g, making it suitable for integration into space-constrained applications.
