40.61.9.012.1303 Finder Miniature PCB relay 1pole 16A DC 12V

Why Choose the Finder 40.61.9.012.1303 Miniature Power Relay?

The Finder 40.61.9.012.1303 is a Series 40 miniature electromechanical power relay intended for electrical switching and industrial control applications. Based on the Finder 40.61 relay platform, it combines a 12 V DC standard coil with a single changeover contact (SPDT / 1 CO), allowing a low-voltage control circuit to operate a separate electrical load.

The Finder 40.61 platform provides a 16 A rated contact current, 250 V AC rated contact voltage and 4000 VA AC1 switching capacity under the applicable manufacturer's specifications. This makes it suitable for a wide range of compatible resistive-load switching, industrial automation and electronic control applications.

The relay belongs to Finder's compact PCB/plug-in relay family, with a nominal body size of 29 × 12.4 × 25 mm. Its miniature construction supports space-efficient electronic equipment and control assemblies. The exact .1303 variant-specific contact, terminal and enclosure characteristics should be checked against the manufacturer's ordering documentation before specifying the relay as a direct replacement.

Reliable 12 V DC Control with High-Current Changeover Switching

The Finder 40.61.9.012.1303 uses an electromagnetic coil to operate its changeover contact. When the appropriate 12 V DC supply is applied, the coil energises and moves the common contact from the normally closed terminal to the normally open terminal. When the coil supply is removed, the relay returns to its normal, de-energised position.

The standard DC coil has a nominal resistance of 220 Ω and draws approximately 55 mA at its rated voltage. Unlike sensitive-coil Series 40 variants, the standard DC coil has a nominal consumption of approximately 0.65 W. The control circuit must therefore be capable of supplying the required coil current.

The relay's 16 A changeover contact enables switching of compatible electrical loads independently of the coil circuit. However, the contact rating must be assessed against the load's voltage, utilisation category, starting current and switching frequency. Motors, transformers, LED drivers and capacitive loads may impose substantially higher inrush currents than their normal operating current.

When designing a PCB or selecting a relay socket, engineers should verify the exact 40.61.9.012.1303 pin arrangement and suffix-specific construction. Suitable PCB track dimensions, wiring, protective devices and coil suppression should be selected according to the installation requirements. For replacement applications, matching the complete manufacturer part number is preferable to matching the coil voltage and contact rating alone.
