FMLB Spring-Loaded Connectors

Mill-Max FMLB Spring-Loaded Connectors are first-mate/last-break connectors in surface-mount or through-hole mounting styles and single- or double-row configurations. Mill-Max FMLB connectors feature spring-loaded pins arranged to efficiently combine power and signal connectors. These connectors achieve this power and signal combination by providing different height and stroke spring pins in the same insulator. FMLB connectors can accommodate the requirements of hot-swap connectors. The FMLB design allows the connector to be grounded before it is connected to the power or after the power is disconnected.
