C04A01

The C04A01 is a charge-mode (PE) uniaxial vibration control accelerometer built on a classic piezoelectric ceramic shear structure with a wide-bandwidth frequency response and a low sensitivity temperature response. With 30 pC/g charge sensitivity and a ±1,000 g range it is the more sensitive member of the family, with 30 pC/g and ±1,000 g for control and monitoring at everyday vibration levels. Typical uses include closed-loop shaker vibration control, product qualification and screening, structural and machinery vibration and general monitoring where a charge amplifier is already in the chain.

With no built-in electronics the sensor works from −40 °C to +160 °C and pairs with any charge amplifier or charge-input vibration controller, which sets the low-frequency limit of the system. High-quality ceramics ensure long-term stability, and the classic core structure is stable, reliable and quick to install and remove between tests. The laser-welded stainless-steel HEX 16.1 × 26.1 mm housing weighs 24.1 g, is sealed to IP68, screws down on an M5 (10-32 opt.) stud and carries a top M5 (10-32 opt.) connector.

Made for vibration control

A stable, repeatable 30 pC/g charge output with a flat ±10% response from 0.5 Hz to 8 kHz and resonance ≥ 25 kHz gives the controller a clean reference signal. 1% non-linearity and ≤ 5% transverse sensitivity, rated to 2,000 g rms vibration and 2,500 g pk shock.

Charge mode, no electronics

With nothing inside to saturate or overheat, the C04A01 runs to +160 °C and works with any charge amplifier or charge-input controller: 780 pF capacitance and ≥ 10¹¹ Ω insulation resistance for a low-noise, long-term stable signal.

Quick to fit, built to last

Laser-welded stainless-steel HEX 16.1 × 26.1 mm housing sealed to IP68 and weighing 24.1 g. M5 × 3.7 (10-32 opt.) mounting stud torqued to 3.0 N·m, with a top M5 (10-32 opt.) connector for a straight cable exit. Easy to install and remove between test setups.
