Overview

The NPP-301A-200AT is a surface-mount absolute pressure sensor based on silicon micromachined technology. It utilizes a four-element Wheatstone bridge configuration to provide a linear millivolt output proportional to input pressure up to 30 PSI. The SO-8 package allows for easy integration onto printed circuit boards where space and reliability are critical.

Why Choose This Part

The sensor offers high accuracy with a linearity of +/-0.2 percent and operates over a wide temperature range of -40C to 125C. Its solid-state design ensures long-term reliability compared to mechanical switches, while the standard SO-8 package simplifies automated assembly.

Applications

Automotive Tire Pressure Monitoring
Used in TPMS modules to monitor tire inflation levels for improved vehicle safety and fuel efficiency.
Industrial Pneumatic Controls
Ideal for monitoring line pressure in factory automation and pneumatic logic systems.
Portable Manometers
Suitable for handheld pressure gauges and digital instruments due to its small footprint and low power consumption.
Consumer Appliances
Integrates into smart appliances for liquid level detection or internal air pressure monitoring.
