Subminiature
Event Counters

 |
|
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. In addition, they have been approved to MIL-I-8974.
A variety of standard configurations are available.
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.
