What Contact Materials are Used in Macromatic Relay Products?

Posted: 11/22/23 | General Information

Author - Mike Johnson, Advanced Design Engineer

The selection of contact material in electromechanical relay contacts is crucial for two primary reasons. Firstly, each contact material exhibits distinct strengths and weaknesses, emphasizing the significance of choosing the most suitable material for a given application. Secondly, compliance with initiatives such as ROHS and REACH, aimed at reducing the use of specific substances, may impact the choice of contact materials.

The contact material utilized in each Macromatic product series is detailed in the accompanying table to facilitate informed decision-making in line with these considerations.
