OMRON Corporation (TSE: 6645, ADR: OMRNY) will introduce on July 1, 2016, two hundred models of “Environment-resistant Series Oil-resistant Components (hereinafter called the Oil-resistant Components)” including sensors and switches with enhanced durability to cutting oils*1 used on automobile production lines.
The two hundred new models of the Oil-resistant Components cover the major devices for factory automation (hereinafter called FA devices) including sensors and switches used in automobile machining processes. All models are designed to resist oil ingress for four years. Strengthening the product lineup of components with superior environmental resistance greatly reduces the risk of sudden stops in production equipment. OMRON’s new Oil-resistant Components will contribute to long-term stable operation of automobile production lines.
In machining processes, failure of FA devices installed in production equipment causes sudden stops in the equipment. These sudden stops are directly linked to decrease in production capacity and shortfalls in production. Several factors can contribute to failures; for example, vibration, shock, ambient temperature, and the effects of dust particles. Most importantly, ingress of cutting oil accounts for 30%*2 of failures. The use of water-soluble cutting oils high in alkaline components has increased, which accelerates deterioration of rubber and resin parts. In a short period of time, part deterioration causes failures in FA devices and becomes a critical factor in reduced operation rates. In addition, at automobile manufacturers conducting global business, it may take time for the local employees to provide maintenance services, so demand for FA devices which are less likely to break down due to cutting oil has grown significantly.
In response, Omron collaborated with a leading cutting oil manufacturer to develop the Oil-resistant Components. By thoroughly analyzing the ingress path of water-soluble cutting oils in FA devices, strengthening sealing materials and improving existing sealing methods, OMRON established itself as a leader in oil-resistant products. Based upon OMRON’s evaluation standards, our products have a four-year resistance to cutting oils.
OMRON will continuously strengthen its “Environment-resistant Series”, tackle a variety of issues at manufacturing sites with its unique technologies, and bring innovation to manufacturing for long-term stable operation.
