688A05 IEPE Single Axis Accelerometer

688A05 IEPE Single Axis Accelerometer (High-G Impact Type)

The 688A05 series is an industrial-grade IEPE single axis accelerometer meticulously engineered to execute precise high-amplitude vibration and dynamic shock measurements within space-constrained testing environments. Featuring integrated internal IEPE signal conditioning circuitry, this low-impedance transducer converts raw internal charge into a highly stable voltage output, allowing for distortion-free data transmission over long cable distances without signal degradation. Specially optimized for extreme transient regimes, the 688A05 pairs a formidable ±2500 g dynamic range with an ultra-stiff internal configuration yielding a resonant frequency ≥ 70 kHz, delivering definitive measurement accuracy for aerospace modal testing, automotive impact diagnostics, and military rocketry research.

Key Features

• Integrated Low-Impedance IEPE Electronics: Utilizes on-board excitation circuitry that conditions the signal internally to provide a clean voltage output, effectively suppressing triboelectric cable noise and environmental electromagnetic interference.

• Severe High-G Shock & Dynamic Survivability: Engineered to withstand sudden, transient mechanical shocks up to 8000 g pk and continuous cyclical high-frequency vibration fields up to 4000 g pk under intense testing profiles.

• Broad 10 kHz Linear Operating Zone: Achieves an exceptional mounted natural resonant frequency ≥ 70 kHz, ensuring excellent frequency tracking response and minimal phase shifting from 5 to 10,000 Hz (±10%)).

• Rugged 1/4-28 Four-Core Electrical Interface: Equipped with a heavy-duty, threaded 1/4-28 four-core multi-pin connector housed within a hermetically sealed titanium or stainless steel shell to guarantee reliable contact and zero fluid ingress.
