Why Choose the Finder 43.61.9.012.0300 Low-Profile PCB Power Relay?
The Finder 43.61.9.012.0300 is a compact 16 A electromechanical PCB power relay designed for reliable electrical switching in industrial automation, electronic control equipment and OEM applications. Part of the Finder 43 Series low-profile relay family, it combines high-current switching capability with a space-efficient construction suitable for printed circuit board assemblies.
Featuring a 12 V DC operating coil and a single normally open (SPST-NO/1 NO) contact configuration, the Finder 43.61.9.012.0300 allows a low-voltage control circuit to switch a separate electrical load. Its silver nickel (AgNi) contact material provides dependable electrical switching performance, while its electromagnetic mechanism maintains galvanic separation between the control coil and contact circuit.
With a 16 A rated contact current, a 250 V AC nominal contact voltage and a 4,000 VA rated AC-1 switching capacity, this relay is suitable for a range of industrial and commercial switching applications. Its 0.4 W DC coil, 5 mm contact terminal pitch and compact low-profile housing support integration into electronic control boards where reliable switching and efficient use of space are essential.

Reliable High-Current Switching for Electronic Control Systems
The Finder 43.61.9.012.0300 uses an electromagnetic operating mechanism to control a normally open contact. When the 12 V DC coil is energised, the contact closes to supply the connected load. When the coil is de-energised, the contact returns to its open position. This provides a straightforward method of switching an electrical load from a separate control circuit.
The 16 A contact rating and AgNi contact material make this relay a practical choice for suitably rated switching duties in electronic equipment and industrial control systems. Its reinforced insulation, RT II flux-proof construction and low-profile PCB terminals support dependable integration into compact electrical assemblies. Load selection should account for inrush current, switching frequency and the relevant AC or DC utilisation category.
Typical Applications
- Industrial automation and machinery control boards.
- Printed circuit board switching assemblies.
- 12 V DC electronic control systems.
