Product Overview
The MS583730BA01-50 from TE Connectivity is an ultra-compact digital pressure and altimeter sensor optimized for deep-water diving and harsh-environment applications. Its hermetic ceramic-metal package with enhanced chlorine-resistant silicone gel ensures long-term reliability. Featuring a high-linearity piezoresistive element, low-power 24-bit Delta-Sigma ADC, and factory-calibrated coefficients, it outputs fully compensated pressure and temperature data via I2C. Rated for 0–30 bar (≈300 m depth) with 50 bar overpressure protection and 0.2 mbar (≈2 mm) resolution, it is ideal for dive computers, marine monitoring, and rugged wearables.instruments.
Core Advantages
0–30 bar Operating Range / 50 bar Overpressure
Designed for deep-water applications with 0 to 30 bar working pressure (≈300 m depth) and 50 bar overpressure rating, ensuring reliability in professional diving and marine environments.
Ultra-High Depth Resolution 0.2 mbar (≈2 mm)
Provides precise depth resolution of 0.2 mbar (approximately 2 mm water depth), enabling accurate tracking of small depth changes in dive computers and underwater instruments.
Enhanced Antimicrobial / Chlorine-Resistant Gel
The “-50” version uses an improved silicone gel formulation with better resistance to chlorinated pool water and seawater, extending service life in harsh aquatic environments.
Low-Power I2C Digital Interface
Standard I2C interface for simple integration, delivering fully calibrated digital pressure and temperature data. Ultra-low power consumption (0.6 µA active, <0.1 µA standby) suits battery-powered underwater devices.

Frequently Asked Questions
Q1: Is your current stock inventory of the MS583730BA01-50 completely original and new?
A: Yes, we guarantee that all MS583730BA01-50 pressure modules in our stock are 100% brand-new, authentic factory parts from TE Connectivity, handled strictly under standard ESD moisture-sensitive tray conditions.
Q2: What is the significance of the “-50” suffix extension on this specific part number code?
A: The “-50” suffix denotes a specialized variant with an enhanced silicone gel blend, providing improved durability and resistance to chlorinated water and seawater for long-term aquatic applications.
Q3: Are there any special handling rules regarding PCB cleaning and assembly for this sensor?
A: Yes. While the sensor is fully compatible with standard SMT reflow profiles, the gel port must never be exposed to ultrasonic cleaning, high-pressure air sprays, or chemical solvents, as these can damage the protective gel layer.
Q4: How can our engineering desk request specific calibration driver samples or mechanical sealing guidelines?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
