High Contact Reliability Resistant to Severe Environments Vibration and Impact (Shock) Resistance Yaskawa Power Reed Switch

When general metal seal contact relays and air break contact relays break DC inductive loads, they have a high tendency of contact wear due to arc discharges(*1). On the other hand, Bestact has a longer service life because the breaking time is short due to the use of glow discharge(*2) when breaking, which results in less wear for the contact. | What is Bestact? Yaskawa Power Reed Switch "Bestact", with an inert gas in a hermetically sealed glass container and its outstanding environmental immunity, durability, and maintainability, truly is the "Best Contact". Compared to products from...
