FSW802B

FSW802B is a FSW800B series, air-flow monitor. It provides a simple but reliable alternative to indicate positive or negative air flow of fans. When properly installed and connected in series with an optical (i.e. LED) or audible signalling device, a bi-directional switch will activate an electrical contact if the air flow of the fan falls below 8.2ft/s, thus either turning the signalling device on or off.

• Reliable mechanical switch contact
• Small size and economical, 1 year warranty
• NO (normally open): contact closed with air flow
• Versatile fields of application
• Contact resistance Incl. wire is 370m, >100,000 cycles service life

• NEMA 1 (IP20) protection, plastic, black housing
• Dimension is 34 x 17.5 x 7.5mm
• 10W (resistive load) max switching capacity
• Operating temperature range from -20 to 50°C
