Reliable Electrical Switching for Industrial Automation
Electromechanical relays such as the Finder 40.61.9.125.1000 allow an electrical control circuit to operate a separate load circuit through electromagnetic switching. When the 125 V DC coil is energised, the internal armature changes the position of the relay contacts, transferring the common connection between the normally closed and normally open terminals.
The Finder Series 40 is developed for applications requiring compact dimensions, dependable switching and flexible installation. The 40.61 relay configuration provides a single 16 A changeover contact, making it suitable for auxiliary control functions, industrial automation equipment and appropriately rated electrical loads. Its compact format enables integration into electronic control assemblies without requiring the installation space associated with larger switching devices.
The relay can be installed directly on a suitable printed circuit board or incorporated into compatible Finder relay socket arrangements. Its galvanically isolated coil and contact circuits make it useful for separating control signals from switched electrical loads. Correct contact loading, protective devices and coil supply conditions should be considered during system design to ensure dependable operation and service life.
