High contact reliability and long lifespan! Rod plunger type auxiliary contact switch.
Rod plunger type auxiliary contacts PSPD and PPMU series
No need for contact polishing due to glass-sealed contacts, and no contact failures from condensation! High contact reliability and long lifespan that you can understand once you use it! Auxiliary contact switch!
Our rod plunger type auxiliary contact switch, PSPD and PPMU series, features glass-sealed contacts, eliminating the need for contact polishing and reducing maintenance labor. It also has a proven track record of high contact reliability in the railway and power markets. The contact section of this product incorporates our original power lead switch, "Bestact," which prevents oxidation and corrosion of the contacts, demonstrating high reliability under various operating environments compared to other products. Bestact achieves a long lifespan with excellent environmental resistance and vibration resistance due to our unique structure, which differs from conventional lead switches. 【Product Features】*Comparison with equivalent products from other companies ○ "High contact reliability": Low failure rate and long lifespan due to unique contact mechanism ○ "Excellent environmental resistance": Minimal long-term degradation from external environments, strong against high temperatures and humidity ○ "High vibration and shock resistance": Strong against vibration and shock due to unique contact mechanism ○ "Low maintenance frequency": Long lifespan reduces maintenance burden If you are looking for a magnetic proximity switch or are dissatisfied with existing magnetic proximity switches, please feel free to consult us. We are delivered by the top runner in industrial robots, Yaskawa Electric Group.

Detailed information
-
This product is equipped with a Yaskawa Power Lead Switch, Bestact. Our products have been recognized for their value by customers over many years in markets that demand high reliability and safety. We have prepared materials to explain "Bestact," the core technology that makes our products long-lasting and highly reliable, so please take a look at the catalog "[Material] What is a Lead Switch?"
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.
