Limit switch achieves high contact reliability even with low-level signals for long lifespan.
Limit Switch PPUU Series
From low-level signal circuits to power circuits, from rare to high-frequency use, you will understand the high contact reliability when you use it! Limit Switch PPUU Series.
Our company's limit switch PPUU series has a wide control load range from low-level signal circuits to power circuits, providing high contact reliability even with infrequent to frequent use. Due to this high reliability, it is widely used as a limit switch for master controllers in railway vehicles. This product features our original power lead switch "Bestact," which has been proven to have high reliability in various operating environments compared to products from other companies. 【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 and strong against high temperatures and humidity ○ "High vibration and shock resistance": Strong against vibration and shock due to unique contact mechanism ○ "Compatible with small to large capacities": Operates with high contact reliability from small to large capacities ○ "Low maintenance frequency": Long lifespan reduces maintenance burden Customers looking for limit switches are welcome to consult with us.

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.
