Honeywell ZephyrTM Analog Air ow Sensors, HAF Series-High Accuracy,

±50 SCCM to ±750 SCCM, Product Nomenclature

Notes:

1. The long port style with the snap mount housing style is not a valid configuration.

2. The 200 SCCM flow range is available in the long and short port styles.

3. Apart from the general configuration required, other customer-specific requirements are also possible.

Please contact Honeywell.

For example, a HAFBLF0200CAAX5 part number defines a Honeywell ZephyrTM Analog Airflow Sensor, bidirectional forward flow optimized, long port, fastener

mount, 200 SCCM, analog output, 10% to 90% transfer function, 5.0 Vdc supply voltage.
