Reliable Power Switching for Industrial Control Systems
Electromagnetic power relays such as the Finder 66.82.8.110.1003 allow industrial control systems to switch electrical loads through mechanically operated contacts. When the 110 V AC coil is energised, the relay transfers its two changeover contacts from their normally closed positions to their normally open positions. When the coil supply is removed, the contacts return to their original state.
The DPDT contact arrangement provides two independent changeover circuits, allowing the relay to perform switching, circuit selection and electrical control functions. Its different normally open and normally closed contact ratings should be considered when selecting the relay for a particular application.
The Finder Series 66 is engineered for high-current switching applications requiring reinforced insulation, robust contact construction and reliable mechanical operation. The silver nickel contact option offers a cadmium-free alternative, while the high switching capacity supports use in industrial machinery, electrical control equipment and power management systems.
Unlike PCB-mounted Series 66.22 relays, the Finder 66.82 configuration incorporates Faston 250 quick-connect terminals and top-flange mounting. This arrangement is particularly suitable for industrial equipment where direct wiring, secure mechanical installation and convenient replacement are important.
