45.71.7.012.1311 Finder Miniature PCB relay 1pole 16A DC 12V

Why Choose the Finder 45.71.7.012.1311 PCB Power Relay?

The Finder 45.71.7.012.1311 is a robust and reliable 16 A electromechanical power relay designed for electrical switching in industrial automation, heating equipment, electronic control systems and OEM machinery. As part of the Finder 45 Series miniature PCB relay range, it combines a sensitive 12 V DC operating coil with a single normally open contact and silver-nickel contact material, providing dependable switching performance in demanding electrical applications.

This relay features a single-pole single-throw normally open (SPST-NO / 1 NO) contact configuration, allowing a low-voltage control circuit to switch a separate electrical load. Its silver-nickel (AgNi) contacts provide reliable switching for suitable industrial and commercial loads, while the sensitive DC coil helps minimise operating power consumption. The RT III wash-tight construction provides additional protection during compatible PCB cleaning and manufacturing processes.

With a 12 V DC nominal coil voltage, 16 A rated contact current and 250 V AC rated contact voltage, the Finder 45.71.7.012.1311 is suitable for heating controls, industrial automation interfaces, electrical equipment and electronic switching assemblies. Its combined PCB mounting and Faston 250 terminal connections provide flexible integration into equipment requiring secure electrical connections and reliable load switching.

Reliable Electrical Switching for Industrial Control Systems

Electromechanical power relays such as the Finder 45.71.7.012.1311 allow low-voltage electronic control circuits to operate separate electrical loads through an electrically isolated switching mechanism. When the specified 12 V DC supply is applied to the relay coil, the internal electromagnetic mechanism closes the normally open contact, allowing current to flow through the controlled circuit. When the coil is de-energised, the contact returns to its normally open position.

The Finder 45 Series is engineered for industrial and commercial equipment requiring dependable switching, high electrical insulation and reliable operation across a wide temperature range. The 360 mW sensitive DC coil helps minimise control circuit power requirements, while the 16 A silver-nickel contact system supports switching of appropriately rated electrical loads. Its reinforced insulation, wash-tight construction and combined PCB/Faston terminal arrangement make it suitable for heating equipment, automation systems and OEM electrical assemblies.
