NPA-500M-030A

Pressure Sensors Transducers Overview

The NPA-500M-030A is a MEMS-based absolute pressure sensor from the Amphenol NovaSensor NPA series. It features a 14-bit digital I2C output and operates within a supply voltage range of 2.7V to 5.5V. The device is rated for a working pressure of 30 PSI (206.84 kPa) with a maximum pressure limit of 60 PSI (413.69 kPa). It utilizes a 14-SOIC package with gull wing termination and top-mounted dual barb ports measuring 0.12 inches (3mm). Accuracy is specified at ±1.5%, and it includes integrated signal amplification and temperature compensation.

Pressure Sensors Transducers Procurement Notes

Verify that the specific suffix 'M' denotes the I2C digital output variant, as other suffixes in the NPA-500 series may indicate analog voltage outputs. Confirm port style compatibility with system tubing requirements. Ensure supply voltage levels align with the 2.7V to 5.5V operational range. Check moisture sensitivity level handling procedures during assembly.

Pressure Sensors Transducers Selection Notes

Select this component when a digital I2C interface is required for absolute pressure measurement up to 30 PSI. The NPA-500M-030A is suitable for applications needing high integration due to its on-chip amplification and compensation. Compare against NPA-500B variants if an analog voltage output is preferred instead of digital communication.

Pressure Sensors Transducers Part Context

This part belongs to the NPA-500 series of low-pressure MEMS sensors by Amphenol Advanced Sensors. The series offers various pressure ratings and output types, including both analog and digital options. The NPA-500M specifically represents the digital I2C version within this family, designed for compact board-level integration in healthcare and industrial sectors.

Pressure Sensors Transducers Replacement Considerations

NPA-500B-030A is a related part but provides an analog voltage output rather than I2C digital output. NPA-700M-030A offers similar digital functionality but differs in supply voltage specifications and potentially pinout or feature sets. Verify electrical compatibility before substitution.
