Yaskawa Power Reed Switch Bestact Provides High Reliability to Your Systems. Additionally Realize Easy Maintenance and Minimization of Your Systems. Bestact Yaskawa Power Reed Switch Due to its outstanding environmental immunity, durability, and maintainability, Yaskawa Power Reed Switch Bestact truly is the “best contact”. As a characteristic, it has the ability of controlling the opening and closing of DC inductive loads. Large- and medium-capacity types are available depending on the application and operating conditions. I/O Relays, Multipole Relays, Limit Switches, Magnetic Proximity...

Bestact improves reliability for various systems and equipment, and provides help for VA Features of Bestact Products Vibration and Impact (Shock) Resistance For large capacity types the vibration resistance is 196m/s² {20G} and the impact resistance is 392m/s² {40G}. The movable contact is small compared with conventional reed switches, and a leaf spring armature holds it (through the use of a specially designed backstop mechanism) against the glass tube wall making it especially strong against vibration and impact, even when not energized. Outstanding operational characteristics under the...
