45.71.7.024.1410 Finder Miniature PCB relay 1pole 16A DC 24VNC

Why Choose the Finder 45.71.7.024.1410 Miniature Power Relay?

The Finder 45.71.7.024.1410 is a compact, high-performance 16 A electromechanical power relay designed for dependable switching in industrial automation, electronic control equipment and OEM electrical assemblies. Part of the established Finder 45 Series, this miniature relay combines a sensitive DC operating coil, normally open power contacts and practical PCB/Faston connections for reliable integration into electrical control systems.

Featuring a 24 V DC sensitive operating coil and a single normally open (1 NO / SPST-NO) contact configuration, the Finder 45.71.7.024.1410 enables low-voltage control circuits to switch appropriately rated electrical loads. Its silver tin oxide (AgSnO₂) contact material provides good resistance to contact welding and makes it suitable for applications involving elevated inrush currents, subject to the relay's published load ratings.

With a 16 A rated contact current, 250 V AC nominal contact voltage and 4,000 VA rated AC-1 switching capacity, this relay is well suited to electronic equipment, heating controls, building automation and industrial machinery. Its compact construction, reinforced insulation and PCB mounting with Faston 250 connections support dependable switching where board space, electrical isolation and load-side connection flexibility are important.

Reliable Switching for Industrial and Electronic Control Systems

The Finder 45.71.7.024.1410 operates by energising its 24 V DC electromagnetic coil to close a normally open contact. When the coil is de-energised, the contact returns to its open position. This provides a straightforward way for an electronic controller to switch a separate electrical load while maintaining galvanic isolation between the control and load circuits.

The 16 A contact rating and AgSnO₂ contact material make this relay a practical choice for suitably rated power-switching applications. Silver tin oxide contacts are particularly valuable where resistance to contact welding is important, although actual suitability depends on load inrush current, utilisation category and switching frequency.

The combination of PCB mounting and Faston 250 connections supports equipment designs requiring compact electronic control circuitry alongside robust load-side connections. Reinforced insulation and flux-proof construction further support integration into professional industrial and commercial equipment.
