L3Harris Event Counters subminiature

The Electrodynamics subminiature event counters were
designed to meet the most difficult requirements of many
military and aerospace applications. These rugged counters
meet or exceed an array of tough environmental specifications
including shock, vibration, temperature and are packaged in a
hermetically sealed miniature enclosure. A variety of mounting
configurations are available as shown on pages 78 and 79.
We also welcome inquires for special requirements.
The ruggedized event counters are assembled and filled with
a dielectric lubricant that dampens the effects of extreme
vibration and thermal shock.
