7D Series

SPECIFICATIONS

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.
