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 most...

Power Reed Switch Medium-Capacity (Element） Type R25 Large-Capacity （Element） Type R15 Highly reliable standard contacts built into Bestact products. ・The contact being enclosed in glass tube with inert gas, it is not affected by the external environment and its characteristics does not change over time. ・The contact reliability is excellent due to the twin contact and wiping effect. ・Due to the carefully selected contact material and the characteristics of the enclosed gas, the switching capacity is significant and the life is long. ・AC/DC dual use, direct control from low level load to power...

Note: Ratings and specifications are defined according to IEC 62246-1. * 1. Rated insulation voltage is the voltage value which is the standard of insulation design and defined by the withstand voltage test. * 2. Rated continuous current is the current value which can continuously flow through the contacts in a closed circuit state without exceeding the specified contact performance and operating characteristics. * 3. Rated operational current is the current value which is combined with a rated operational voltage and used in regulated conditions (making/breaking current, switching frequency...

ELECTRICAL LIFE Electrical life tabulated below is B₁₀ value in a single test （at the condition shown in IEC 62246-1-1）at Yaskawa. It is not a value in a multiple environment such as temperature and vibration. It is necessary to test actual products before initial operation. The circuit that drives coils adopts a direct making method which applies rated coil voltage（instant ON and instant OFF）. In the circuit where the voltage applied to coils gradually increases or decreases, electrical life might decrease. Also, in the circuit where exceeded the rated operating voltage and current of contacts,...
