HALF SIZE CRYSTAL CAN RELAY
2 AMPERE SENSITIVE
Product Description
Series
KA
Innovation and versatility of design has allowed Hi-G to achieve this improved sensitivity of our basic military qualified product. The
product reflects an improved magnetic circuit powering our standard contact structure to levels of 2 amperes. The internal structures
reflect and conform to the latest military specifications and are supported by a continuing qualification program. Product performance,
reliability and sensitivity are reflected in this unique device and provide the design engineer with a tool for improved circuit design.
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 2 amperes switching
-
2 form C, DPDT contacts, special metal alloy with gold plating
-
Frame, armature designs and force / mass ratio provides exceptional immunity to shock and vibration.

Insulating Pad
Relays can be supplied with a insulating pad
epoxied to the relay header, to prevent the
possible shorting of printed circuit board land
lines and to facilitate circuit board cleaning. To
order relay with pad add. “P” to Part Number.
