40.61.9.048.1300 Finder Miniature PCB relay 1pole 16A DC 48V

Why Choose the Finder 40.61.9.048.1300 Miniature Power Relay?

The Finder 40.61.9.048.1300 is a compact 16 A miniature electromechanical power relay from the Finder 40 Series, featuring a 48 V DC standard coil, a single normally open (1 NO) contact and silver nickel (AgNi) contact material. Designed for industrial automation, electronic control equipment and electrical load switching, this relay provides a reliable interface between low-voltage DC control circuits and separately supplied electrical loads.

The 40.61.9.048.1300 uses a single-pole normally open (SPST-NO) contact configuration, making it suitable for applications where an electrical circuit must close when the relay coil is energised. Its RT II flux-proof construction supports suitable PCB assembly processes, while the compact housing allows integration into industrial control equipment and OEM electronic assemblies.

Featuring a 0.65 W nominal DC coil, 3.5 kΩ nominal coil resistance and approximately 14 mA nominal coil current, the relay supports efficient control from compatible 48 V DC circuits. Its 16 A contact rating, 250 V AC rated switching voltage and compact PCB-compatible design make it a versatile solution for electrical switching applications.

Reliable 48 V DC Normally Open Switching for Industrial Automation

The Finder 40.61.9.048.1300 provides an effective interface between 48 V DC control electronics and electrical load circuits. Its normally open contact remains open while the coil is de-energised and closes when the appropriate control voltage is applied. When coil power is removed, the contact returns to its open position, providing straightforward control of connected equipment.

The relay's standard 0.65 W DC coil has a nominal resistance of 3.5 kΩ and draws approximately 14 mA at its rated voltage. These characteristics help engineers select suitable controller outputs, electronic relay drivers and coil suppression components for industrial control applications.

The silver nickel (AgNi) contact material provides a cadmium-free contact option for electrical switching applications. The relay's RT II flux-proof construction is designed to protect the internal mechanism during suitable soldering processes. It should not be confused with RT III wash-tight construction, which provides additional protection for compatible cleaning processes.

The 16 A normally open contact is suitable for electrical loads within the relay's applicable ratings. Motors, inductive equipment and loads with high inrush currents require particular attention to switching categories, contact endurance and protective devices. The complete 40.61.9.048.1300 part number should be checked before substituting it for another Finder 40.61 relay, particularly where contact configuration or environmental protection differs.
