43.41.7.018.0000 Finder Miniature PCB relay 1pole 10A DC 18V

Why Choose the Finder 43.41.7.018.0000 Low-Profile PCB Power Relay?

The Finder 43.41.7.018.0000 is a compact and reliable low-profile electromagnetic PCB power relay designed for electrical switching in industrial automation, electronic control equipment and machinery applications. As part of the established Finder Series 43 relay range, this model combines dependable switching performance with a space-saving construction suitable for printed circuit boards and compatible relay sockets.

Featuring an 18 V DC sensitive coil and one changeover contact (SPDT / 1 CO), the Finder 43.41.7.018.0000 enables electrical loads to be controlled using a low-power DC signal. Its silver-nickel (AgNi) contacts provide reliable electrical switching, while its monostable electromagnetic mechanism ensures that the contacts return to their normal position when the coil is de-energised.

With a 10 A rated contact current, a 250 V AC rated contact voltage and a compact body measuring approximately 30.2 × 10.2 × 15.4 mm, this relay is suitable for electronic control boards, automation interfaces and industrial equipment. Its 3.2 mm contact pin pitch and low-profile PCB construction support straightforward integration into compact electrical assemblies.

Reliable Low-Power Switching for Industrial Electronic Control Systems

Electromagnetic relays such as the Finder 43.41.7.018.0000 provide electrically isolated switching between low-voltage control circuits and connected electrical loads. When the 18 V DC coil is energised, the internal electromagnetic mechanism changes the position of the relay's changeover contact, allowing the connected electrical circuit to be switched. When the coil supply is removed, the contact returns to its normal position.

The Finder Series 43 is designed for compact electronic assemblies requiring reliable switching, low coil power consumption and effective electrical isolation. Its 0.25 W sensitive DC coil, 10 A contact rating and low-profile PCB construction make the 43.41.7.018.0000 suitable for industrial control boards, automation interfaces and OEM electronic equipment. The combination of reinforced coil-to-contact insulation, compact dimensions and durable electromagnetic operation supports dependable integration into modern electrical control systems.
