Broadening lineup of PCB-mounted
components that are smaller andrequire less wiring and labor

The term industrial relay & components collectively refers tovarious electrical components incorporated into control panels/
units used to operate and control machinery and productionlines. They are used for a wide range of applications, including
automated warehouses, industrial machinery, and semiconductor
manufacturing equipment, and so on.
Responding to ever-growing needs for “smarter” facilities
and equipment, space-saving, and quality stabilization, IDEC
adds new technologies to control panel components to provide
operator-friendly production environments offering greater
efficiency and convenience. This is another way that we help
customers find solutions to various challenges.

Decentralization of control units is increasingly being used as asolution for two challenges concerning control panels/units—shrinking their size and reducing the development/assembly
workload. The control units can be cut out from the large control
panels and made into blocks to achieve greater usability andenhance the value chain from development and production tosales and maintenance. There is thus an accelerating trend tomake control units into printed circuit boards (PCBs) for greaterutility. Also, demand for PCB-mounted components is likely togrow with the emergence of new apparatus that set new norms,
and with the rising number of components that leverage IoTtechnology. IDEC has been developing, manufacturing, andselling PCB-mounted components such as industrial relays,terminal blocks, and circuit protectors. We will continue to focus
on launching new products in the market.

CompletedNew surface-mounted terminal block thatleverages our mechanical technology
We have launched a revolutionary terminal block that customers caneasily assemble without installation tools. This unique design allows
terminal blocks to easily stacked and assembled by rotating them. This
helps users to be reduce workload, as they can flexibly accommodate
sudden changes in specs and perform maintenance. Since shaft
screws are not used to connect the terminal blocks, the design reduces
the number of parts involved, an advantage that also helps to protect
the environment.

The Suzhou factory mainly manufactures RJ series
industrial relays, which are in high demand in theChinese market. We have streamlined production byadopting automated assembly machines in 2017 andby overhauling our parts supply system to optimize
inventory. We added more automated assembly
machines in FY2023, and plan to install a line of laborsaving machines in FY2024.
We will continue endeavoring to stabilize quality
and costs and to shorten delivery times so that we canmore reliably serve customer needs.

GovernanceUsing spring-loaded technology: Push-in products, which can be easily
wired by simply plugging in the terminals, can reduce wiring work andachieve stable quality compared to screw products. This provides
benefits that reform how work is done at manufacturing sites, including
prevention of errors by less experienced workers and reduction ofovertime work.
