Reliable Power Switching for Industrial Automation and Electrical Control
Electromechanical power relays such as the Finder 66.22.9.110.4000 enable an electrical control circuit to switch separate power circuits through an electromagnetic operating mechanism. When the 110 V DC coil is energised, the relay changes the position of its internal contacts, allowing connected electrical loads to be switched according to the control signal. The DPDT configuration provides normally open and normally closed switching paths for flexible control arrangements.
The Finder Series 66 is designed for industrial applications requiring reliable electrical switching and effective separation between control and load circuits. Its reinforced insulation, robust contact construction and PCB mounting arrangement make it suitable for integration into electrical control equipment, industrial machinery and OEM electronic assemblies. Correct PCB conductor sizing, protective devices and load assessment are essential when operating at higher switching currents.
Typical Applications
- Industrial automation and electrical control systems.
- PCB-mounted power switching assemblies.
