AC292-M12A Series Premium Compact Accelerometer

The CTC AC292-M12A Series is a premium compact accelerometer designed for high-precision vibration monitoring in demanding industrial environments. With a sensitivity of 100 mV/g (±5%) and a wide frequency response from 0.3 Hz to 15 kHz (±3 dB), this sensor delivers accurate and reliable vibration data with superior RF immunity. Its compact design and 4-pin M12 connector make it ideal for installations where space is limited but performance cannot be compromised.

Constructed with a shear-mode PZT ceramic sensing element housed in a hermetically welded 316L stainless steel case, the AC292-M12A offers excellent durability and environmental resistance. It withstands shocks up to 5,000 g peak and operates reliably across a broad temperature range from -58°F to 250°F (-50°C to 121°C). The sensor is submersible to 60 meters and comes with a 1/4-28 blind tapped mounting hole for secure installation. Backed by CTC’s unconditional lifetime warranty, the AC292-M12A is a versatile and robust choice for condition monitoring and diagnostic applications.
