Harting Ethernet switch offers high availability
Harting's industrial Ethernet switches range is believed to be the first to offer ring redundancy to achieve high system availability, while simplifying network configuration and ease of operation.
As more daughter cards are becoming entirely populated with surface-mount components, this means that all components for the daughter card, including connectors, can now be placed automatically and reflow soldered in one step.
The new connectors have been designed to exploit the latest developments in simultaneous double-sided reflow soldering (SDSRS) and pin-in-hole intrusive reflow (PIHIR) technology.
HARTING has integrated open ventilation slots into the wafers and connector housings to provide free air flow, guaranteeing good heat distribution and providing homogeneous heat dissipation to aid uniform cooling of the soldered joints.
The 'open' design of the robust and rigid moulding ensures a rapid and even heat distribution even at the high temperatures required for lead-free soldering, while also allowing the utilisation of the familiar temperature profiles.
Another advantage of the open moulding is the short time needed for the heating of all contact rows.
Therefore, when reflow soldering takes place alongside much smaller components, the connector is no longer a time-critical item.
The surface-mount compatible connectors use the same hole configuration as traditional press-fit versions, allowing easy conversion to the new technology.
With this new concept, hard metric 2 mm connectors can for the first time be fully integrated into the economic reflow soldering process.
