With configurable thresholds, the FMA Series can be easily installed for use in a variety of applications, including commercial and automotive HVAC and industrial air filters, engine air filtration systems and rooftop units exposed to pressure or vacuum environments. With hydrophobic reference port and sealed connection system, it can also be used in a variety of harsh environmental conditions. The FMA Series is available in multiple positive or vacuum pressure ranges, mating with an integrated AMPSEAL 16 (3-way) electrical connector (Drawing No. C-776402-1-GEN) and a 1/8-27 NPT female pressure connection port. ## Applications ## Features - Engine Air Filter Restriction - Cabin Pressure - HVAC Pressure - Exhaust Pressure - Industrial Filters - Supply Voltage: 5VDC - Linear Output: 0.5V to 4.5V (Ratiometric) - Diagnostic Features (Bridge Connection Checks, Bridge Short Detection, Power Loss Detection) - Temperature-Compensated - Sealed AMP Electrical Connector - Multiple Pressure Ranges Available (Vacuum and Pressure) - Fast Response Time - REACH & RoHS Compliant **Amphenol Advanced Sensors** ## Technical Specifications ## **Electrical** |Supply Voltage (VDD)(1)|5 VDC +/-5%| |---|---| |Supply Current|5 mA Max| |Output Voltage (VO)
