TE Connectivity FS-90/1 Flow Switch 3 L/min - 15mm SPST-NO Copper Brass Housing
The TE Connectivity FS-90/1 is a compact, single-pole single-throw normally open (SPST-NO) flow switch designed for water and air flow detection in industrial control and monitoring systems. It activates at a flow rate of 3 liters per minute, featuring a durable brass housing and copper shuttle for reliable performance in HVAC, pump protection, and fluid handling applications.
Features
- SPST-NO (Single-Pole Single-Throw Normally Open) contact configuration for simple on/off flow detection.
- Precise activation at a 3 L/min flow rate, suitable for low-flow monitoring and pump protection circuits.
- Rugged brass housing and copper shuttle construction ensures durability and corrosion resistance.
- Wide operating temperature range from -25°C to 85°C for use in demanding industrial environments.
- Low pressure drop design minimizes system impact and operates from a small head of water.

The FS-90/1 flow switch from TE Connectivity operates on a mechanical principle where fluid flow moves an internal shuttle, which actuates a single-pole, single-throw, normally open (SPST-NO) electrical switch. This simple, reliable design provides a direct digital signal for flow presence, making it ideal for integration into PLCs, alarm systems, and equipment protection circuits.
Engineered for water and compatible with air, the switch features a brass housing and a copper shuttle for long-term reliability in various media. Its robust construction withstands pressures up to 10 bar at 20°C and vibrations up to 35g, ensuring stable operation in industrial settings such as cooling systems, filtration units, and fluid dispensing equipment.
