Magnetic proximity switches widely adopted in high-temperature environments of steel and port facilities.
Magnetic proximity switch PSMS series for high temperature
Our high-temperature non-contact magnetic proximity switches, which are durable and reliable in high-temperature and high-humidity environments like steel mills where water and oil are present, are performing excellently!
The hot finishing rolling mill at the steelworks is a representative piece of equipment for steel plate rolling, commonly referred to as a hot strip mill. In an environment characterized by heat dissipation from the hot strip and the scattering of large amounts of cooling water and lubricating oil, our high-temperature separate-type magnetic proximity switch has been adopted. This product features our original power lead switch "Bestact" built into the contact section, which prevents oxidation and corrosion of the contacts, demonstrating high reliability under various operating conditions compared to other products. Due to its robust mechanism that can withstand harsh environments, it is a long-lasting magnetic proximity switch. The environmentally resistant magnetic proximity switch enables our customers to reduce maintenance, workload, and costs.

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.
