A series of ultra miniature hermetically sealed relays with .100 inch grid spaced terminations. These relays are similar to MA series TO-5
relays construction and are provided for the operation in military and/or commercial equipment and/or installations with increased
mechanical and environmental requirements.
The following construction features ensure the highest reliability in extreme environments:
-
All welded relay construction
-
Cleaning and sealing techniques ensures maximum internal cleanliness
-
Low level to 1 ampere switching
-
2 form C, DPDT contacts, special metal alloy with gold plating
-
Frame design and force / mass ratio provides exceptional shock and vibration immunity
Low intercontact capacitance and contact circuit losses, provides also a reliable switching functions in demanding RF applications, combined with small
size and low coil power dissipation (see figure 1).
