[Case Study] Port Equipment: Long-lasting Limit Switches with Excellent Environmental Resistance
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, improving 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 part uses Bestact with glass-sealed contacts, ensuring no oxidation or corrosion of the contacts, providing 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 trusted and used in various markets where reliability and safety are essential, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of standard relays and a failure rate of 1/20 under low loads, we 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 conditions, such as in vegetable factories where humidity is present.
