Honeywell 24PCAFA6G Ultra-Low Pressure Sensor 1 PSI Gage Vacuum 4-SIP Module

The Honeywell 24PCAFA6G is a premium ultra-low board-mount pressure sensor engineered for micro-level gage and vacuum measurement up to 1 PSI. While some systems integrate the alternative 24PCFFA6G configuration for higher limits, this highly sensitive 4-pin SIP module delivers a raw unamplified millivolt output with a fast 1 ms response time, making it exceptional for precision medical respirators and HVAC leak detection.

Experience exceptional accuracy in micro-fluidic environments with the genuine Honeywell 24PCAFA6G ultra-low pressure sensor. Belonging to the renowned 24PC family, this component features a specialized piezoresistive silicon chip that captures minuscule pressure deviations with a scale of plus or minus 1.0 PSI.
Unlike the high-pressure 24PCFFA6G variant which targets massive industrial flows, the 24PCAFA6G focuses entirely on low-span accuracy. It incorporates a straight barbless port architecture and operates on an uncompensated Wheatstone bridge configuration. This gives circuit engineers total control to design proprietary calibration, thermal compensation, and operational amplifier stages tailored to their device hardware.
Key Technical Specifications:
  • Manufacturer: Honeywell
  • Factory Part Number: 24PCAFA6G

  • Maximum Overpressure Safety Limit: 20.0 PSI max
  • Typical Sensitivity: 45 mV/psi (Highly responsive)
  • Excitation Voltage: 10 VDC typical to 12 VDC maximum
  • Full Scale Span Output: 45 mVdc typical (Analog millivolt)
  • Interfacing Termination: 4-SIP module style (Single-in-line through-hole)
  • Response Framework Time: 1 ms maximum
  • Port Interface: 0.2 inch straight plastic tube interface port

Application Matrix:
Due to its unique low-pressure sensitivity, it is heavily used in medical breathing ventilators, cleanroom HVAC differential monitoring, diagnostic laboratory analyzers, and gas chromatography instruments. If your board-level layout previously accommodated the 24PCFFA6G footprint, this 1 PSI model will fit the exact same 4-pin printed circuit board configuration while maximizing resolution for low-scale operations.
Choose the 24PCAFA6G to achieve professional-grade reliability in small-footprint instrumentation devices.
