NPA-500B-05WG

Pressure Sensors Transducers Overview

The NPA-500B-05WG is a board-mount pressure sensor from the NPA-500 series, manufactured 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 with a full-scale range of 0.18 PSI (1.25 kPa) and a maximum overpressure limit of 60 PSI (413.69 kPa). Accuracy is specified at ±1.5%. It utilizes a 14-SOIC package with top ports and operates within a temperature range of -40°C to 125°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific pressure rating and port configuration against application requirements before ordering. Confirm that the 14-SOIC surface mount package aligns with PCB layout constraints. Ensure supply voltage matches the 4.75V to 5.25V specification. Check moisture sensitivity level handling procedures during assembly to maintain component integrity.

Pressure Sensors Transducers Selection Notes

Select this model for low-pressure gauge applications requiring amplified analog output. Consider the 0.18 PSI range suitability for sensitive flow or pressure differentials. Evaluate the 14-SOIC footprint for space-constrained designs. Compare accuracy and temperature range against other NPA-500 variants if higher pressure ranges are needed.

Pressure Sensors Transducers Part Context

Part of the NPA-500 series of MEMS pressure sensors offering various pressure ranges and output types. The NPA-500B variant specifically denotes gauge pressure measurement capability. This series is designed for board mounting, integrating signal conditioning directly on the chip to simplify interface circuitry for end-users.

Pressure Sensors Transducers Replacement Considerations

NPA-500B-005G offers a similar gauge pressure profile but with a 5 PSI range instead of 0.18 PSI. Both share the same 14-SOIC package and analog output characteristics. Verify pressure range compatibility when substituting to ensure measurement accuracy within the target application limits.
