Microwave Design Solutions for Smart Connectivity

Inside a microwave exists a power and signal distribution system expertly engineered for safe operation within a limited space. This requires compact, durable connectors capable of efficiently handling high voltage. Engineers designing microwaves depend on Molex's space-saving, high-power connectors—featuring heat-resistant materials, secure locking systems and keyed designs—to ensure reliable and safe operation.

Microwave Connectivity Solutions for Efficient Appliance Design


Safely distributing high-voltage power in tight spaces requires efficient, dependable connectivity solutions that prevent overheating and electrical failures. While heat-resistant connectors are crucial to endure high temperatures, the confines of microwaves demand compact connectors that simplify assembly without sacrificing functionality.

Design engineers can utilize high-current connectors with secure retention and keying features to ensure safe and stable power delivery to high-voltage components. Glow Wire capable, heat-tolerant materials provide durability under prolonged thermal stress. Furthermore, compact connectors with secure mating mechanisms facilitate integration in densely packed layouts, ensuring electrical isolation and efficient assembly.

Molex provides high-voltage, high-current connectors with strong terminal retention and multiple keying options, designed to meet the rigorous power delivery requirements of microwave subsystems. Engineered for thermal resilience, these connectors meet IEC 60335-1 safety standards and utilize Glow Wire capable materials to safeguard against failures in high-heat areas. Additionally, Molex’s space-saving designs are equipped with secure locking mechanisms that streamline integration in dense configurations while ensuring reliable mating and performance.

Control Board Connectors for Microwaves


In the intricate design of microwave control boards, engineers must incorporate high-power connectors within tight spaces while managing thermal stress and mechanical vibration. Molex connectors are engineered for reliability in harsh microwave environments, offering low mating force, secure locking mechanisms and robust terminal designs. These capabilities streamline assembly and reduce operator fatigue while ensuring consistent long-term performance in high-heat, vibration-prone conditions.
