7D Series
PCB Mount
PRODUCT DESCRIPTIONS
The 7D Series is a miniature reed relay, which comes in
1 Form A and 2 Form C configurations. This is the smallest
horizontal mounting relay in our product line. Form E is used
instead of Form C in order to achieve 300 million times of
operations. We mainly provide this series to probe card
industries and the instrumentation division in IC
manufacturers.
