Limit switches are widely used in harsh environments such as port facilities due to their long lifespan.
Limit switch PIKU
A limit switch with high contact reliability even in harsh environments and excellent environmental resistance! It extends the lifespan of your products and equipment and improves operational reliability!
Port facilities are exposed to environments accompanied by dust, corrosive gases, and rainwater (sludge) due to the large handling of raw materials (various ores, coal, etc.) and the location conditions of coastal areas. In such circumstances, the limit switch PIKU-110R25A-01, which incorporates Yaskawa's power lead switch "Bestact," is used on girders as a countermeasure against slip accidents on rails during acceleration and deceleration of the unloader's club trolley. It is also used for conveyor applications. The contact section uses Bestact, which has glass-sealed contacts, ensuring no oxidation or corrosion of the contacts, resulting in exceptional reliability. Bestact achieves a long-lasting product with excellent environmental resistance and vibration resistance due to our unique structure, which differs from conventional reed switches.

Company information
For over 40 years, our relays and sensors have been used in various markets where reliability and safety are required, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of general relays and a failure rate that is 1/20 under minimal loads, our products contribute to improving equipment reliability while also reducing running costs by decreasing the frequency of replacements. Leveraging the excellent environmental resistance of our products, they perform well even in harsh environments, such as in vegetable factories where humidity is present.
