Overview

Asahi Onkyo Co., Ltd. is a Japanese company based in Shichijō that describes itself as a manufacturer of industrial wireless radio equipment used to remotely operate machinery, cranes and hazardous-material handling equipment in factories and construction/civil-engineering sites. The company states it builds wireless devices that can operate cranes and machines from any manufacturer, offers custom-made products, and is the only company with a lineup of explosion-proof wireless devices. Its product lineup includes cableless remote-control models such as the Smart Cableless RC-50000, Slim Cableless, Microcomputer Cableless, Tough Cableless and Mid Cableless series, as well as data cableless units, receivers, batteries and chargers.

History

According to the company's About Us page, its predecessor developed a voice changer that was a forerunner of karaoke, and the company inherited that business, which is why the word 'Onkyo' (acoustics) remains in its name. When karaoke machines became widespread and the voice changer was no longer needed, the company discussed what to make next; at a time when amateur radio was popular, one person built a device that could start a car engine remotely, with the catchphrase 'Engine start OK from your room!' Although that product did not sell well, the technology allowed the company to enter the industrial wireless remote-control industry. Its first hit was described as the world's first handheld wireless remote-control device, with the catchphrase 'Cableless rather than cable,' and production and sales reportedly tripled at once; the handheld type it developed is now said to be the industry standard.
