Product Category Overview


Solid State Relay (SSR) is an electronic switch that uses semiconductor devices to achieve contactless switching functions. Compared to traditional electromagnetic relays, SSRs have advantages such as no mechanical wear, fast response, long lifespan, and resistance to vibration. They are mainly used in circuits requiring frequent switching, such as industrial automation, home appliance control, and communication equipment. SSRs use optocouplers to isolate the input and output, ensuring high reliability and low noise in circuit control.
