Quartz Flexure Accelerometer (±50–±70 g) — JDSJ25TK01Product reference

Confirm configuration, interfaces and documentation with your inquiry.

The JDSJ25TK01 series quartz flexure accelerometer is a high-precision inertial navigation-grade sensor renowned for its exceptional long-term stability, repeatability, startup performance, environmental adaptability, and high reliability. It is suitable for both static and dynamic testing and also functions effectively as a standard vibration and tilt sensor. The accelerometer’s output current maintains a linear relationship with the applied force or acceleration, allowing users to select appropriate sampling resistors to achieve high-precision outputs. Additionally, an internal temperature sensor can be integrated upon request to compensate for bias and scale factor variations, thereby minimizing environmental temperature influences.
