40.61.9.018.1001 Finder Miniature PCB relay 1pole 16A DC 18V

Why Choose the Finder 40.61.9.018.1001 Miniature PCB Power Relay?

The Finder 40.61.9.018.1001 is a compact miniature electromechanical power relay from the Finder 40 Series, featuring an 18 V DC standard coil and a 16 A single changeover contact. Designed for industrial automation, electronic control equipment and electrical switching applications, this relay provides an effective interface between low-voltage DC control circuits and separately supplied electrical loads.

Part of Finder's established 40.61 relay family, this model combines high-current switching capability with a compact PCB-compatible construction. Its single-pole double-throw (SPDT) contact arrangement provides both normally open and normally closed connections, allowing one control signal to operate a changeover switching function.

The 18 V DC standard coil has a nominal power consumption of approximately 0.65 W, a nominal resistance of 500 Ω and a rated current of 36 mA. Combined with the 40.61 family's 250 V AC rated switching voltage and 4000 VA AC1 resistive switching capacity, these characteristics make the relay suitable for a variety of industrial and OEM control applications.

Reliable 18 V DC Switching for Industrial Automation

The Finder 40.61.9.018.1001 provides a practical interface between 18 V DC control electronics and electrical load circuits. When its coil is energised, the relay transfers its changeover contact from the normally closed position to the normally open position. When the coil is de-energised, the contact returns to its normal state, enabling straightforward control of auxiliary equipment and electrical switching functions.

The relay's standard 0.65 W DC coil has a nominal resistance of 500 Ω and draws approximately 36 mA at its rated voltage. These characteristics help engineers select suitable relay driver circuits, control outputs and protective components for electronic equipment.

The Finder 40.61 platform provides a 16 A changeover contact in a compact miniature housing. Its PCB-compatible format makes it useful for electronic control assemblies, while compatible socket arrangements may be selected where the exact relay pin configuration and mounting requirements permit.

When switching motors, inductive equipment or loads with high inrush currents, the applicable utilisation category and contact ratings must be considered rather than relying solely on the resistive AC1 rating. The complete 40.61.9.018.1001 part number should also be checked against manufacturer documentation before substituting it for another Finder 40.61 variant.
