New Endevco 7262A — Amplified Output Piezoresistive Accelerometer

The Endevco® 7262A is a rugged, gas‑damped, DC‑response piezoresistive accelerometer with amplified output. It is engineered for long‑duration transient shocks and high‑level events common to EV powertrain abuse tests, sled/impact studies, and aerospace component/LRU qualification. A compact, epoxy‑sealed body with integral 4‑conductor cable simplifies installation while maintaining high signal fidelity.
Key benefits
- DC response with amplified output for capturing long‑duration transients.
- Wide dynamic options: ±100 g, ±500 g, ±1000 g ranges.
- Robust, environmentally sealed construction (IP67) with integral cable.
- Lightweight (~6 g) for minimal mass loading.
- ISO 17025 calibration supplied (sensitivity, ZMO, frequency response).
Applications
- Avionics LRUs and equipment structural shock on benches
- Landing gear and actuator transient shock characterisation
- Handling/transport shock qualification for flight hardware
- Ground rigs with long‑duration shock pulses where DC response is required

Integration notes
- Wire for differential or single‑ended readout; maintain good grounding and shielding practice.
- Use short, well‑routed harnesses; avoid parallel runs with high‑current switching paths.
- Mount on a flat, clean surface; torque 2‑56 fasteners as per datasheet guidance.
- Verify channel range, anti‑aliasing, and sampling for the expected shock pulse width.
