SAF Series Air Velocity Switch

The solid state SAF Series airflow switch assures dependable thermal control and protec-

tion for air cooled systems. The SAF Series advantages include:

Can drive logic circuits, audible/optical alarms and magnetic relays

Available in sealed and dust-proof versions

Can be socket mounted, PCB or hard wired

Available in 50 to 1500 linear feet per minute ranges

Not affected by ambient temperatures

5 VDC design with low power dissipation

Signal conditioning not required

The advanced SAF Series Airflow Switch provides early detection and protection from overheating in high-end

computer systems and peripherals, large power supplies, HVAC equipment, medical diagnostic systems and other

electronic systems requiring forced air cooling.

The patented* design is based on a heated thermistor which monitors the airstream and detects a loss or

reduction of airflow due to fan failures, clogged filters or obstructions in the air inlet/outlet. The thermistor

temperature and, therefore, its resistance, is affected by changes in air velocity. The SAF thermistor is part of a

sensing bridge which compares its own resistance against a reference circuit and determines the air velocity at

which the device will trigger an output.

The innovative, low profile airflow sensor is easily mountable directly on the most densely populated circuit

boards with as little as .625 inch spacing between boards, in sockets or bracket mount in plenums. All SAF

models are complete, self-contained sensor/alarm devices requiring no additional circuitry.

*US Patent No. 4,686,450
