NPA-500B-030G

Pressure Sensors Transducers Overview

The NPA-500B-030G is a board-mount pressure sensor from the NPA-500 series by Amphenol Advanced Sensors. It features an analog voltage output ranging from 0.5V to 4.5V with a supply voltage of 4.75V to 5.25V. The device measures gauge pressure up to 30PSI (206.84kPa) and withstands overpressure up to 60PSI (413.69kPa). Accuracy is specified at ±1.5%. It utilizes a 14-SOIC package with top ports, operating between -40°C and 125°C.

Pressure Sensors Transducers Feature Summary

• Integrated signal amplification for direct interface compatibility
• Factory temperature compensation ensures stable performance across wide thermal ranges
• Surface-mount design with top-mounted dual barbed ports for compact integration

Pressure Sensors Transducers Applications

• Medical gas delivery systems
• Respiratory equipment monitoring
• HVAC differential pressure sensing
• Industrial process control instrumentation

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status as per manufacturer documentation. Confirm that the 14-SOIC package matches PCB footprint requirements. Ensure supply voltage rails strictly adhere to the 4.75V to 5.25V specification to prevent output saturation or damage. Validate port dimensions against tubing specifications prior to assembly.

Pressure Sensors Transducers Selection Notes

Select this model when an amplified analog voltage signal is required rather than raw millivolt outputs. The 0.5V to 4.5V range facilitates direct connection to standard ADC inputs without additional gain stages. Consider the NPA-300 series if lower supply voltages are necessary, or the NPA-700 series for digital I2C communication needs instead of analog interfaces.

Pressure Sensors Transducers Part Context

This component belongs to the NPA-500 series of MEMS pressure sensors designed for low-pressure applications. It shares the same physical footprint and mounting style with other variants in the family but differs in output type and pressure rating. The series is optimized for medical and industrial environments requiring high reliability and small form factors.

Pressure Sensors Transducers Replacement Considerations

Direct pin-compatible replacements within the same series include models with different pressure ratings such as NPA-500B-015G or NPA-500B-060G. Cross-series substitution requires careful evaluation of output linearity and supply voltage compatibility.
