Endevco has announced the debut of model 12M1B, a high performance, high impedance piezoelectric accelerometer, packaged as a surface mount chip component.
The sensor is expressly designed for seamless integration into standard hybrid or SMT electronics packages, along with custom designed signal conditioning units, allowing the engineer to create miniaturized shock and vibration measurement systems in one completely integrated package.
Weighing just 120 mg and reliably operating in temperatures up to +150°C, model 12M1B features Endevco's Piezite-type P-8 bimorph sensing element, operating in bender mode. This material offers low base strain sensitivity, low pyroelectric output, and extremely high charge output versus size. Contact with the P-8 sensing element is made via two thick film gold metallic mounting pads, located on the bottom surface of the aluminum case. As model 12M1B is a high impedance piezoelectric device, extreme care must be exercised in shielding it from stray electromagnetic noise.
With its strong performance characteristics and extremely compact envelope size, model 12M1B is ideal for use in low-cost, high volume and OEM applications, as well as the manufacturing and testing of electronic devices, security systems, medical devices (such as pacemakers and cardiac defibrillators), wireless "smart structures", smart motor tools and accelerometer loggers within the oil, gas and petrochemical industry, as well as within numerous other highly sensitive environments.
