The new Har-bus 64S from Harting is a passive mechanical switching connector for use in VME64x bus systems.

The 5-row, 160-way connector offers automatic daisy-chain functionality without incurring contact losses.

The switching elements close the daisy chain when no daughter card is inserted, eliminating the need for active components or jumpers on VME64x backplanes. Five pairs of switching contacts short-circuit the VME interrupt lines when the daughter card is removed, preserving the integrity of the entire system.

Fully compatible with Har-bus 64 daughter card connectors, the 64S also offers full backward compatibility with existing standard VME systems based on 3-row type C daughter card connectors on a 2.54 mm in according to DIN 41612.
