What ダイヤトレンド株式会社 does

Diatrend Corporation (ダイヤトレンド株式会社) is a privately held Japanese industrial cable and networking equipment manufacturer founded in 1971 and headquartered in Kita-ku, Osaka. The company specializes in factory-automation connectivity products, manufacturing and distributing servo motor cables, interface cables, optical fiber cables, CC-Link cables, and EtherNet/IP/EtherCAT industrial Ethernet cables compatible with the major Japanese automation platforms — Mitsubishi Electric (MELSEC series), FANUC, Yaskawa Electric, Omron, Panasonic, Oriental Motor, and Sanyo Denki. It also sells industrial networking equipment including PoE switches and injectors, media converters, optical transceivers, wireless LAN adapters, and surveillance cameras, and offers a custom cable manufacturing service built around customer wiring diagrams.

The company operates a B2B direct-sales model combining a proprietary e-commerce storefront (ec.diatrend.com) for catalog items with inquiry-based quotation for custom cables, OEM products, and higher-value items such as mobile wire storage racks (DWR series). Product pricing is denominated in yen and largely unit-based (e.g., ¥4,048 per meter of EtherNet/IP cable, ¥518,650 for a 3-tier slim wire storage rack). Distribution is domestic to Japan with limited evidence of international channels; the company also distributes third-party networking brands (PLANET, TRENDnet, GeoVision) as a reseller. In 2023-2026, Diatrend has steadily expanded its networking line with PoE++ (IEEE802.3bt, 90W) products, RS-232C↔USB converter cables, interface-converter full-set bags, and most recently (mid-2026) a substrate coating service for 26 industrial hub models and a 67-SKU expansion of industrial optical transceivers targeting data-center demand. The company is CC-Link Partner Association certified and holds UL758-2464 and RoHS compliance on key cable SKUs.
