43.61.9.048.0300 Finder Miniature PCB relay 1pole 16A DC 48V

Why Choose the Finder 43.61.9.048.0300 Miniature PCB Power Relay?

The Finder 43.61.9.048.0300 is a compact 16 A miniature electromechanical power relay designed for reliable electrical switching in industrial automation, electronic control equipment and machinery. Part of the Finder 43 Series, this low-profile relay combines high-current switching capability with space-efficient PCB mounting for demanding electrical control applications.

Featuring a 48 V DC operating coil and a single normally open contact (1 NO / SPST-NO), the Finder 43.61.9.048.0300 allows a separate control circuit to switch compatible electrical loads. The contact closes when the coil is energised and returns to its open position when the coil supply is removed, providing straightforward, non-latching operation.

With a 16 A rated contact current and a 250 V AC rated contact voltage, this relay is suitable for industrial switching applications where the connected load remains within the manufacturer's specified limits. Its compact, low-profile construction and through-hole PCB terminals make it particularly useful in OEM control boards, automation equipment and industrial electronic assemblies.

Key Advantages

• Compact 16 A miniature power relay for industrial and electronic control applications.
• 48 V DC nominal coil voltage for compatible DC control systems.

Reliable 48 V DC Relay Switching for Industrial Control Systems

The Finder 43.61.9.048.0300 operates through an electromagnetic switching mechanism. Applying the appropriate 48 V DC supply to the relay coil generates a magnetic field that moves the internal contact mechanism, closing the normally open contact and completing the connected load circuit.

The single normally open contact arrangement makes this relay suitable for applications where an electrical load should remain disconnected until a control signal is present. This arrangement is useful for equipment enable circuits, auxiliary load switching and automation systems requiring a defined normally open switching state.

Its 16 A contact rating and compact PCB-mounted construction make the Finder 43.61 platform a practical choice for electronic equipment manufacturers and industrial control engineers. When selecting the relay, the actual switching duty must be checked against the manufacturer's ratings, particularly for motors, inductive loads, capacitive loads and circuits with high inrush current.
