NPA-700B-02WD

Pressure Sensors Transducers Overview

The NPA-700B-02WD is a board-mount differential pressure sensor from the Amphenol NovaSensor NPA-700 series. It features a measurement range of -2 to 2 inches of water (inH2O) with an accuracy of ±2.5% full scale. The device provides digital output via an I2C interface and utilizes a 16-bit resolution. It operates within a supply voltage range of 2.7V to 5.5V and supports a temperature range of -40°C to +125°C. The component is housed in a SOIC-14 package with dual barbed ports for fluid connection.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix '02WD' against official Amphenol datasheets to confirm the exact pressure range and port configuration, as variations exist within the NPA-700 family. Ensure compatibility with the target I2C bus voltage levels and check for RoHS compliance status prior to final procurement approval.

Pressure Sensors Transducers Selection Notes

Select this model when a low-pressure differential measurement in the inH2O range is required with digital output. Consider the SOIC-14 package size constraints and the need for dual barbed connections. Evaluate if the ±2.5% accuracy meets application requirements compared to higher precision alternatives in the same series.
