40.61.9.012.1001 Finder Miniature PCB relay 1pole 16A DC 12V

Why Choose the Finder 40.61.9.012.1001 Miniature PCB Power Relay?

The Finder 40.61.9.012.1001 is a compact 16 A miniature electromechanical power relay from the Finder 40 Series, designed for industrial automation, electronic control systems and electrical load switching. Featuring a 12 V DC standard coil, a single changeover contact and a wash-tight RT III construction, this relay provides dependable switching in applications requiring additional protection during electronic assembly and cleaning processes.

The Finder 40.61 relay configuration combines a single-pole double-throw (SPDT) contact arrangement with a compact PCB-compatible housing. Its normally open and normally closed contact paths enable a low-voltage control signal to operate a separately supplied electrical circuit, making it suitable for OEM machinery, electronic equipment and industrial control applications.

Unlike the sensitive DC coil variants identified by coil code 7, the 40.61.9.012.1001 uses Finder's standard 0.65 W DC coil. The relay features a 16 A rated contact current, 250 V AC rated switching voltage and 4000 VA AC1 resistive switching capacity, while its wash-tight construction provides additional protection during suitable PCB manufacturing processes.

Key Advantages

• 16 A rated contact current supports switching of appropriately rated electrical loads.
• 12 V DC standard coil provides compatibility with suitable low-voltage DC control systems.
• 0.65 W nominal coil power provides predictable electrical requirements for coil driver design.
• Wash-tight RT III construction provides additional protection during compatible electronic assembly and cleaning processes.

Dependable DC-Controlled Switching for Industrial Automation

The Finder 40.61.9.012.1001 provides an effective interface between 12 V DC control circuits and electrical switching applications. When the relay coil is energised, the changeover contact transfers from its normally closed position to its normally open position. When coil power is removed, the contact returns to its normal state, allowing straightforward control of auxiliary circuits and connected equipment.

The relay's standard 0.65 W DC coil has a nominal resistance of 220 Ω and draws approximately 55 mA at its rated voltage. These characteristics are important when selecting electronic relay drivers, controller outputs and suitable coil suppression components.

The RT III wash-tight construction distinguishes this variant from standard flux-proof versions. This feature is useful in electronic manufacturing environments where suitable PCB cleaning processes are employed. Wash-tight protection relates to the relay's construction and should not be interpreted as a general-purpose waterproof enclosure rating.

With its 16 A changeover contact, the Finder 40.61.9.012.1001 is suitable for a variety of electrical switching duties when the connected load remains within the applicable ratings. Inductive equipment, motors and loads with high inrush currents require particular attention to utilisation categories, switching capacity and circuit protection.
