GSRBA500D Quartz Flexible Accelerometer

GSRBA500D is a solid-state digital-output accelerometer built on quartz flexible technology. Unlike traditional analog sensors, it delivers direct digital readings with fast start-up and minimal power draw. ±70g range and 22×22×14mm compact housing. Bias stability ≤100μg, second-order nonlinearity ≤80μg/g2, noise floor ≤10μg — delivering precision previously found only in larger devices. 400Hz bandwidth and 200g shock tolerance with -45°C to +85°C operation. Quartz design inherently resists shock and vibration, offering long-term stability analog accelerometers cannot match. The sensor consumes just 5mA at 15V, making it ideal for aerospace, aviation, navigation, military weapons, and vehicle systems where reliability and accuracy are mission-critical.
