Finder 43.61.9.006.0300 – 43 Series PCB relays

Why Choose the Finder 43.61.9.006.0300 Low-Profile PCB Power Relay?

The Finder 43.61.9.006.0300 is a specified 6 V DC, 16 A low-profile PCB power relay belonging to the Finder 43 Series. Designed for compact electrical switching applications, the 43.61 relay family combines a high-current normally open contact with a slim housing and reinforced electrical insulation between the control and load circuits.

The 43.61-0300 configuration features a single-pole normally open (SPST-NO / 1 NO) contact and a 5 mm contact pin pitch. This arrangement is intended for straightforward on/off control, allowing an appropriately rated DC coil circuit to operate a separate electrical load. The relay is particularly suited to printed circuit board assemblies where reliable contact switching and compact component dimensions are important.

Important specification note: Finder's published 43.61 standard DC coil range lists 12 V, 24 V and 48 V DC, but does not list a standard 6 V DC coil. Although the supplied part number contains the coil code 9.006, the exact 43.61.9.006.0300 configuration could not be confirmed against the published standard coil table. Its nominal coil voltage, resistance, operating range and availability should therefore be verified with Finder before ordering or designing the control circuit.

High-Current Normally Open Switching for Industrial Control

The Finder 43.61-0300 relay configuration is designed for applications requiring a compact, high-current normally open contact. When its DC electromagnetic coil is energised, the relay closes the contact to complete the load circuit. Removing coil power allows the contact to return to its normally open position, making this design suitable for auxiliary control, load activation and electronic switching functions.

Its 16 A contact rating and reinforced coil-to-contact insulation make the 43.61 family useful in industrial PCB assemblies. However, the 9.006 coil designation in the requested SKU is not included among the standard coil versions shown in Finder's published documentation. Engineers should obtain confirmation of the exact coil characteristics and product availability before finalising the PCB design, drive circuitry or purchasing specification.
