Overview
TR-CM400 circular imaging sonar transducer is designed for high-resolution 360° underwater scanning, obstacle avoidance and close-range target detection. Equipped with 144 independent channels and 400kHz high frequency, it delivers finer azimuth resolution compared with lower-frequency circular sonar.
Compact circular outline, small size and light weight, easy to integrate on mini ROV, AUV, USV and underwater monitoring equipment. Rated depth up to 300m, widely used for underwater inspection, pipeline survey, harbour security and aquaculture net cage checking. Custom watertight connectors, cable harness and mounting adapters are available.
