Why Choose the Finder 45.71.7.012.1410 PCB Power Relay?

The Finder 45.71.7.012.1410 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 closed contact and silver-nickel contact material, providing dependable switching performance in demanding electrical applications.

This relay features a single-pole single-throw normally closed (SPST-NC / 1 NC) contact configuration, allowing the controlled circuit to remain connected while the relay coil is de-energised. When the coil is energised, the contact opens to interrupt the connected load. Its silver-nickel (AgNi) contact material supports reliable switching of suitable industrial and commercial electrical loads, while the sensitive DC coil helps minimise control circuit power consumption.

With a 12 V DC nominal coil voltage, 16 A rated contact current and 250 V AC rated contact voltage, the Finder 45.71.7.012.1410 is suitable for industrial controllers, heating systems, HVAC equipment and electronic switching assemblies. Its PCB mounting arrangement with Faston 250 contact connections provides practical integration into electrical equipment, while its high-temperature construction supports operation in demanding environments.

Reliable Electrical Switching for Industrial Control Systems

Electromechanical power relays such as the Finder 45.71.7.012.1410 allow low-voltage electronic control circuits to operate separate electrical loads through an electrically isolated switching mechanism. Unlike normally open relays, this model uses a normally closed contact, meaning the switching circuit is connected when the relay coil is not energised. Applying the specified 12 V DC supply to the coil opens the contact and interrupts the connected circuit.

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, high-temperature capability and PCB/Faston terminal arrangement make it suitable for heating equipment, automation systems and OEM electrical assemblies.

Typical Applications

  • Industrial automation and electronic control systems.
  • Burners, boilers and furnace control equipment.
  • Heating, ventilation and air conditioning (HVAC) systems.
  • Industrial electrical switching assemblies.
  • Automatic door and gate control systems.
  • Electronic control boards for household appliances.
  • Extractor fans and ventilation equipment.
  • Refrigeration and temperature control systems.
  • Industrial ovens and heating appliances.
  • Equipment requiring normally closed control contacts.
  • Commercial electrical equipment and OEM machinery.
  • PCB-based control assemblies with Faston electrical connections.
