All Silicon Designs accelerometers are highly rugged and reliable industrial-grade MEMS capacitive chips and modules that can continue to operate after shock exposures of up to 10,000 g and 2000 g, respectively, yet do not experience the resonant frequency constraints that are most typically common to piezoelectric and piezoresistive accelerometers. The use of proprietary manufacturing technologies allows for on-board voltage regulation and an internal voltage reference, making units relatively insensitive to temperature and voltage changes, while integral amplification eliminates the need for external power amplification. Carefully controlled manufacturing processes ensure that each sensor is made virtually identical, allowing users to swap out units with little or no modifications. SURFACE MOUNT ACCELEROMETERS - MODEL 1221 Size: "L" SUFFIX PACKAGE "J" Lead 0.35"sq. x 0.17" "L" Lead 0.35"sq. x 0.10" Mass: 0.62 to 0.68 grams SPECIFICATIONS UNITS 1221 Power Requirements V DC +5 Differential Output (Single Ended) V ±4 (0.5 to 4.5) Temperature Range °C -55 to +125 Model 1221 is a low-cost, integrated accelerometer for use in zero-to-medium frequency instrumentation applications that require extremely low noise and are available in both "L" and "J" style packages. Each miniature, hermetically sealed package combines a MEMS capacitive sensing element and a custom integrated circuit that includes a sense amplifier and differential output stage. It is relatively insensitive to temperature changes and gradients. Each device is marked with a serial number on its bottom surface for traceability. An optional calibration test sheet is also available which lists measured bias, scale factor, linearity, operating current and frequency response.
