The TURCK FCS-G1/2A4-AP8X-H1141 is a compact flow sensor designed for monitoring flow rates of liquids in pipelines. It features a G1/2" process connection and provides a PNP normally open (NO) output. With an adjustable switching point, it reliably detects whether flow is present or absent, making it ideal for coolant circuits, water-based processes, or pump monitoring. Built with a rugged housing and IP67 protection, it is suitable for demanding industrial and automation environments. Key Features: • Flow sensor for liquid media • Process connection: G1/2" (BSPP) • Output type: PNP normally open (NO) • Adjustable switching point • LED status indication • Operating voltage: 15…30 VDC • IP67 protection for harsh environments • Ideal for water, oil, and coolant monitoring systems
