Reliable Electrical Switching for Industrial Automation

Electromechanical relays such as the Finder 40.61.9.021.1300 allow electrical circuits to be switched using a separate control voltage. When the relay coil is energised, its internal electromagnetic mechanism operates the contacts, enabling the connected electrical load to be controlled without requiring the control circuit to carry the load current directly.

The Finder 40.61 relay platform is particularly suitable for applications where compact dimensions, electrical isolation and dependable switching performance are important. Its 16 A contact rating makes it useful for controlling compatible electrical loads, while the reinforced insulation between the coil and contacts supports safe circuit separation when correctly installed.

The 21 V DC coil enables operation from a suitably rated DC control supply. The relay can be integrated into electronic control boards, industrial machinery and electrical control assemblies, making it a practical solution for equipment manufacturers, maintenance engineers and industrial automation specialists.
