Overview
SensorTech’s preamplifiers have been designed for applications where size and weight are critical but performance cannot be compromised. The SA12 is ideal for use with piezoelectric sensors such as hydrophones and vibration detectors but can also be used in other applications. Surface-mount technology provides small size, yet reliable, low-noise configuration. The SA12 offers high input impedance and low power consumption.
The SA12 has a two-wire single-ended input and output. The SA12 is a phantom-powered preamplifier with a 23dB gain. Versions are also available in 7dB, 15dB and 20dB gains. (Minimum orders apply, please call technical support for more details.)
