LEMO is expanding its field-proven M series with a vacuum tight model, named HY, available in all sizes and low voltage configurations. This fixed socket model has been specifically designed for all applications requiring vacuum tight integrations in harsh environments.

Thanks to an innovative potting material the HY model is enabling vacuum tight sealing with ultra-low leak rates over a broad temperature range.

It also integrates optimized PCB tails enabling easier PCB routings, even on high density configurations. The mass connection has also been improved and now offers the possibility to use either standard ground pins or special anti-vibrations threaded holes for “screw through” PCB fixation.

This addition to the M series lineup is providing customers with the highest density ratchet coupling connectors on the market where vacuum tight integrations are required. The ultra-low leak rate coupled to its wide temperature range allow for unmatched performances in optical enclosures or high-altitude applications.
