YASKAWA HERMETICALLY SEALED CONTACT
Open the catalog to page 1Maximum Contacting Reliability, Minimized Size and Get them from Bestact Bestact is a hermetically sealed power switching contact unit having an excellent reputation in great number of actual applications as an interface element for control systems. Customer-proven features of Bestact include maximum reliability as well as unsurpassed environmental immunity and durability under adverse conditions such as high temperature, high humidity, existance of gas or vapor, vibration and surge. Large- and medium-capacity types are available depending upon customer's applications. 5 series of...

Open the catalog to page 3BESTACT PRODUCTS IMPROVES RELIABILITY O FEATURES OF THE BESTACT SERIES OF PRODUCTS Bestact = Conventional Reed Switches + Mechanical Power Relays Bestact can perform the jobs of both conventional reed switches and power relays. Because a single Bestact replaces both, circuitry is simplified and entire circuit reliability rises significantly. A substantial cost savings can be achieved in that no contact protection (snubbers/diodes) is needed, minimal connections and reduced wiring circuitry is realized in actual circuit design. Vibration and Impact (Shock) Resistance In its weakest axis...
