B02YG1

The B02YG1 is a case-isolated three-axis IEPE accelerometer built on a piezoelectric ceramic shear structure with a wide-bandwidth frequency response and a built-in miniature integrated circuit. With 10 mV/g sensitivity and a ±500 g range it is the high-range model in the family, built for high-level triaxial vibration and moderate shock. Typical uses include HALT/HASS screening, automotive NVH on powertrain and chassis components, durability testing and general triaxial monitoring.

High-quality ceramics ensure long-term stability and the built-in low-impedance circuit keeps noise low. The laser-welded titanium-alloy 12.5 × 12.5 × 15.8 mm housing weighs 9.5 g and has an integrated insulation design with double shielding that isolates the signal ground from the test structure (≥ 10⁸ Ω) and gives strong EMI immunity. A single 1/4-28 4-pin connector carries all three channels on one four-core cable, and the sensor mounts on an M5 stud with a 10-32 thread version available.

Case isolated, EMI immune

Integrated insulation design with double shielding gives ≥ 10⁸ Ω isolation between signal ground and the mounting surface, so multi-channel tests on conductive structures stay free of ground loops and electrical noise, with no insulating pad or base to fit.

Three axes, one stud

Simultaneous X, Y and Z measurement from a single compact block with ≤ 5% transverse sensitivity. Stud mounting with an M5 thread (10-32 optional) and a 1/4-28 4-pin connector for one four-core cable.

Built-in IEPE electronics

Miniature low-impedance circuit with 2–20 mA constant-current excitation and 8–12 V bias. Spectral noise of 40 µg/√Hz at 100 Hz and 0.001 g rms broadband resolution, rated to 2,000 g rms vibration and 5,000 g pk shock, with bandwidth to 8 kHz and resonance ≥ 50 kHz.
