Global PhotoMOS Optically Isolated Relay Market Overview and Analysis of Panasonic, OMRON, Toshiba, NEC, IXYS, BRIGHT TOWARD, COSMO Electronics, Okita Works and more

PhotoMOS Optically Isolated Relays are electromechanical relays that use light instead of an electrical current to perform switching operations. They can be used in a range of applications where it is necessary to isolate a circuit from the power source, as they use light-driven signals. PhotoMOS Relays offer electrical isolation between the control signal and the load, thereby eliminating potential short circuits from the electric shock of electricity as well as reducing any EMI/EMC problems found in other relays. PhotoMOS relays are a type of solid-state relay (SSR) that employs optically coupled components to switch an output circuit utilizing an input signal. The optocoupler, or optoisolator, provides electrical isolation between the input and output circuits, allowing the input signal to control the output without electrical interaction between the two sides. The relays are available in a range of sizes and styles which can make them suitable for variety of applications.

PhotoMOS relays have wide-ranging applications across the globe, primarily in applications that need high electrical isolation, low-level and low-voltage switching, and high-frequency circuit control. They are often used in telecommunications equipment, HVAC and lighting control, elevators, motor controllers, and some types of consumer electronics. PhotoMOS relays are also extensively used in Automation, especially where electrical safety is critical and isolation between system components is paramount. Additionally, these relays are increasingly being used in medical and military applications due to their inherent robustness. PhotoMOS also offers an efficient and cost-effective solution for applications in electrical and solar energy industries.

The global PhotoMOS Optically Isolated Relay market was valued at US$ 387 million in 2022 and is anticipated to reach US$ 576.9 million by 2029, witnessing a CAGR of 5.8% during the forecast period 2023-2029. The influence of COVID-19 and the Russia-Ukraine War were considered while estimating market sizes.
