Reliable Low-Profile Switching for Electronic Control Systems
Electromechanical relays such as the Finder 43.41.7.003.0000 use an electromagnetic coil to control a separate electrical switching circuit. When the 3 V DC coil is energised, the internal armature transfers the common contact from the normally closed terminal to the normally open terminal. When the coil supply is removed, the relay returns to its normal contact position.
The Finder Series 43 is designed for electronic equipment requiring low-profile construction, sensitive DC coil operation and dependable electrical switching. The 43.41 configuration provides a 10 A changeover contact with reinforced insulation between the coil and contacts, making it suitable for appropriately designed control circuits that require separation between low-voltage electronics and switched electrical loads.
The relay's 250 mW coil consumption supports integration into low-power electronic control systems, while its PCB-compatible construction allows straightforward installation in compact circuit assemblies. The 3.2 mm contact pin pitch and compatibility with suitable Finder PCB sockets provide additional installation flexibility. Engineers should ensure that the coil-driving circuit can supply the required operating current and that connected loads remain within the relay's applicable switching ratings.
