NPA-700M-02WG

Pressure Sensors Transducers Overview

The Amphenol Advanced Sensors NPA-700M-02WG is a board-mount pressure sensor from the NovaSensor NPA-700 series. It features an I2C digital output with 14-bit resolution and measures gauge pressure up to 2 inches of water column (H2O). The device utilizes a manifold port interface and is housed in a SOIC-14 surface mount package. It operates within a supply voltage range of 2.7V to 5.5V and functions across a temperature range of -40°C to +125°C. Accuracy is specified at ±1.5% FSO, with a maximum overpressure capability of 60 PSI.

Pressure Sensors Transducers Procurement Notes

Verify that the specific part number suffix matches the required pressure range and port type, as the NPA-700 series offers various configurations. Confirm moisture sensitivity handling requirements during storage and assembly, as indicated by the component specifications. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging quantities to avoid partial reel restrictions. Cross-reference the datasheet for any recent product change notifications affecting pinout or electrical characteristics.

Pressure Sensors Transducers Selection Notes

Select this model when a low-pressure gauge measurement up to 2 inches H2O is required with digital I2C connectivity. The SOIC-14 package facilitates automated surface mount assembly, reducing manufacturing complexity compared to through-hole alternatives. Consider the ±1.5% accuracy specification against application tolerances. The wide operating temperature range supports deployment in both clinical and industrial environments where thermal stability is critical for consistent performance.

Pressure Sensors Transducers Part Context

This component belongs to the NovaSensor NPA-700 series, which provides economical solutions for board-mounted pressure sensing. The series includes variants with analog mV outputs, amplified signals, and different pressure ranges. The NPA-700M-02WG specifically targets low-pressure gauge applications using a manifold port, distinguishing it from barbed or threaded variants within the same family designed for higher pressures or different fluid interfaces.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes within the NPA-700 series include NPA-700M-001G for 1 PSIG gauge pressure and NPA-700M-030G for 30 PSIG gauge pressure. Verify that the replacement maintains the same SOIC-14 footprint and I2C communication protocol. Ensure the new variant's pressure range and port type match the mechanical constraints of the target application.
