40.61.9.014.4303 Finder Miniature PCB relay 1pole 16A DC 14V

Why Choose the Finder 40.61.9.014.4303 Miniature Power Relay?

The Finder 40.61.9.014.4303 is a compact 16 A electromechanical miniature power relay from the Finder Series 40, designed for reliable electrical switching in industrial automation, electronic control equipment and printed circuit board assemblies. Combining a compact housing with a high-current contact system, this relay is suitable for equipment manufacturers and automation engineers requiring dependable switching within space-constrained electronic designs.

Featuring a 14 V DC nominal coil voltage, a single changeover contact (1 CO / SPDT) and a 16 A nominal switching current, the Finder 40.61.9.014.4303 provides an effective interface between low-voltage DC control circuits and compatible electrical loads. Its electromechanical construction provides galvanic separation between the control coil and switching contacts.

This variant features gold-plated silver-alloy contacts, making contact material selection an important distinguishing characteristic. Its PCB mounting arrangement, compact dimensions and monostable operation support integration into industrial control electronics, machinery interfaces and OEM equipment requiring reliable switching performance.

Key Advantages

• 14 V DC nominal coil: Designed for compatible low-voltage DC control circuits.
• 16 A nominal switching current: Suitable for appropriately rated electrical loads.
• Single changeover contact: Provides normally open and normally closed switching functionality.

Reliable 14 V DC Coil Operation

The Finder 40.61.9.014.4303 operates through an electromagnetic coil that changes the position of its single changeover contact. When the 14 V DC coil is energised, the common contact transfers from the normally closed terminal to the normally open terminal. Removing the coil supply allows the contact to return to its original position, providing straightforward control of compatible electrical circuits.

The standard DC coil has a nominal resistance of 300 Ω and draws approximately 47 mA at its rated voltage, corresponding to approximately 0.65 W of coil consumption. The manufacturer's Series 40 coil data specifies an operating range of approximately 10.2–21 V DC for the 14 V standard DC coil, supporting operation within the specified supply conditions.

Gold-Plated Contacts and 16 A Switching Performance

The Finder 40.61.9.014.4303 incorporates gold-plated silver-alloy contacts, distinguishing it from standard contact variants within the Series 40 family. The gold-plated contact finish provides a specialised surface characteristic that may be beneficial in applications where contact interface behaviour is important. Contact selection should always consider the intended switching voltage, current and load characteristics.

With a 16 A nominal contact current and a rated contact voltage of 250 V AC, the relay is suitable for compatible auxiliary electrical switching applications. The maximum switching voltage is 400 V AC, although the permissible load depends on the contact configuration, operating conditions, inrush current and load category. The applicable manufacturer ratings should be checked when designing equipment.
