LL964C and LL964H
OEM, military and ocean engineering only
A higher impedance version of the LL916 for acoustic barriers and harbour defence. It runs over very long cables with minimal loss.
Overview
The LL964C (in a cage) and LL964H (in a harness) are high performance piezoelectric underwater acoustic transducers. They are the high impedance version of the popular LL916, which lets them run on very long cables with little loss.
They work in tanks, rivers and the open sea, and can be special ordered with an underwater pluggable Subconn bulkhead connector.
