Why Choose the Finder 40.61.7.024.2021 Miniature Power Relay?

The Finder 40.61.7.024.2021 is a 24 V DC miniature electromechanical power relay from the established Finder 40 Series, designed for electrical switching, industrial automation and control applications. The Finder 40.61 relay family combines a compact construction with a single changeover contact (1 CO / SPDT) and a 16 A rated contact current, making it suitable for a wide range of electrical control and equipment manufacturing requirements.

Featuring a 24 V DC sensitive-coil configuration, the 40.61.7.024 relay platform allows a compatible low-voltage control circuit to operate an electrically isolated switching contact. The 40.61 family offers a 250 V AC rated contact voltage and a 400 V AC maximum switching voltage, subject to the manufacturer's specified load conditions. Its changeover contact provides both normally open and normally closed switching functions, offering flexibility for control, signalling and interlocking circuits.

The Finder 40.61.7.024.2021 belongs to a relay range used in compact electrical assemblies, PCB-based control equipment and industrial switching systems. The 40.61 series is available in different contact-material, terminal and mounting configurations. As the complete .2021 ordering suffix has not been independently verified, variant-specific features should be confirmed against the corresponding Finder manufacturer documentation before installation or replacement.

Compact 24 V DC Relay Switching for Industrial Control Systems

The Finder 40.61.7.024.2021 belongs to a miniature relay family designed for switching electrical loads through low-voltage control circuits. Its 24 V DC coil makes it relevant to industrial automation systems where 24 V DC is commonly used for control signals, PLC outputs and auxiliary control equipment. When the coil is energised, the relay changes the state of its contact, allowing a suitable control circuit to operate a separate electrical load.

The single changeover contact provides a common connection, a normally closed contact and a normally open contact. This configuration is useful where a control system requires alternative switching paths, status indication or interlocking functions. The changeover arrangement can also simplify control circuit design when a single relay must provide both normally open and normally closed outputs.

With a 16 A rated contact current, the Finder 40.61 family offers substantial switching capability for a miniature relay. However, the maximum permissible load depends on the electrical characteristics of the circuit. Resistive loads, inductive loads, motors and equipment with high inrush currents may require different switching ratings. The 16 A rating must not be treated as a universal rating for every load type; engineers should check the appropriate AC1, AC15, motor or DC switching specifications before selecting the relay.

The standard 24 V DC sensitive-coil configuration uses approximately 0.5 W of nominal coil power, with a nominal resistance of 1,150 Ω. These characteristics can be useful when designing relay-driving circuits, but the controller or output module must still be capable of supplying the required coil current. Suitable suppression and protection should be considered where necessary, particularly when the relay is driven by an electronic output.

The Finder 40.61 miniature construction makes the relay family suitable for compact electrical control equipment. PCB-mounted versions can be integrated into electronic assemblies, while appropriate plug-in versions can be used with compatible relay sockets for convenient maintenance. Because different 40.61 variants may have different terminal arrangements, contact materials and construction options, the complete 40.61.7.024.2021 part number should be verified before selecting a PCB footprint, socket or replacement relay.
