Datasensing S70 fiber optic amplifier provides high performance detection offering small object detection and fast response time in high speed or low contrast applications. Two models are available with different selectable response speeds: S70-E1 with 200 µs (High Speed), 500 µs (Standard), 2 ms (Long Range), and 5 ms (Extra Long Range). S70-E2 with 10 µs (Super High Speed), 15 µs (High Speed), 50 µs (Fast), 250 µs (Standard), 500 µs (Medium Range), and 1 ms (Long Range).The double digital display shows both signal level and threshold, and bright LEDs indicators ease the programming and status monitoring during operation. S70 features a single discrete output, either NPN or PNP, and a model with IO-Link interface is also available. The amplifiers work with any 2.2 mm fiber optics, available in Datasensing OF range as standard, high efficiency, ultra-flexible, and high temperature version.
