40.61.9.048.1001 Finder Miniature PCB relay 1pole 16A DC 48V

Why Choose the Finder 40.61.9.048.1001 Miniature PCB Power Relay?

The Finder 40.61.9.048.1001 is a compact miniature electromechanical power relay from the Finder 40 Series, featuring a 48 V DC standard coil and a 16 A single changeover contact. Designed for industrial automation, electronic control equipment and electrical load switching, this relay provides an effective interface between DC control circuits and separately supplied electrical loads.

Part of Finder's established 40.61 relay family, the relay features a single-pole double-throw (SPDT) contact arrangement, providing both normally open and normally closed switching functions. Its compact PCB-compatible construction makes it suitable for electronic assemblies, industrial control systems and original equipment manufacturer (OEM) applications.

The 48 V DC standard coil has a nominal power consumption of approximately 0.65 W and a nominal resistance of 3.5 kΩ. The Finder 40.61 contact platform provides a 250 V AC rated switching voltage and 4000 VA AC1 resistive switching capacity, supporting a wide range of appropriately rated electrical switching duties.

Reliable 48 V DC Switching for Industrial Automation

The Finder 40.61.9.048.1001 provides a practical interface between 48 V DC control electronics and electrical load circuits. When the relay coil is energised, its changeover contact transfers from the normally closed position to the normally open position. When the coil is de-energised, the contact returns to its normal state, providing predictable electrical switching for industrial equipment.

The relay's standard 0.65 W DC coil has a nominal resistance of approximately 3.5 kΩ and draws approximately 14 mA at its rated voltage. These characteristics are useful when selecting electronic relay drivers, controller outputs and suitable coil suppression components. A correctly designed driver circuit should accommodate the relay's coil voltage and switching requirements.

The Finder 40.61 platform combines a 16 A changeover contact with a compact miniature housing. Its PCB-compatible construction supports integration into electronic control assemblies, while compatible Finder 95 Series sockets provide alternative mounting arrangements where the exact relay pin configuration permits.

For reliable switching, engineers should evaluate the connected load against the applicable contact ratings and utilisation category. Motors, inductive equipment and loads with high inrush currents may require additional protection or a switching device specifically rated for the intended duty. When replacing another Finder 40.61 relay, the complete part number should be checked to confirm coil, contact, mounting and construction compatibility.
