40.61.7.024.1321 Finder Miniature PCB relay 1pole 16A DC 24V

Why Choose the Finder 40.61.7.024.1321 Miniature Power Relay?

The Finder 40.61.7.024.1321 is a miniature electromechanical power relay from the Finder Series 40, designed for industrial automation, electronic control systems and electrical load switching. Combining a 24 V DC sensitive coil with a 16 A single changeover contact (1 CO / SPDT), this relay provides an efficient switching interface between low-voltage control electronics and compatible electrical loads.

The Finder 40.61 family is widely used in control panels, electronic equipment and machinery where compact dimensions, dependable switching and straightforward integration are important. Its monostable operating mechanism ensures that the relay returns to its normal contact position when coil power is removed, making it suitable for conventional control and signalling circuits.

With a 250 V AC rated contact voltage, sensitive DC coil technology and compact Series 40 construction, the Finder 40.61.7.024.1321 offers a practical solution for equipment manufacturers, maintenance engineers and industrial automation specialists. The complete ordering suffix identifies a specific construction variant and should be retained when ordering an exact replacement.

Reliable Electromechanical Switching for Industrial Control Systems

The Finder 40.61.7.024.1321 provides a practical interface between a 24 V DC control circuit and an electrically isolated switching contact. When the coil is energised, the relay transfers its common contact from the normally closed connection to the normally open connection. Removing the control voltage allows the internal spring mechanism to return the contacts to their original position.

This monostable switching action is useful in industrial automation systems where the electrical contact must follow the state of the control signal. Typical functions include enabling auxiliary circuits, providing status signals, switching compatible loads and isolating control electronics from the switched circuit.

The sensitive DC coil has a nominal consumption of approximately 0.5 W, making it suitable for appropriately rated electronic control outputs. The controlling device must be capable of supplying the required coil current, and suitable suppression should be considered where necessary to protect semiconductor outputs against switching transients.

The 16 A rated contact current provides switching capability for a variety of compatible electrical loads. However, the permissible current depends on the application. Resistive loads, motors, contactor coils, capacitive circuits and LED drivers can have significantly different switching characteristics. Engineers should therefore select the relay according to the relevant Finder load ratings rather than relying on the nominal contact current alone.

As part of the Finder Series 40, the relay benefits from a compact construction intended for electronic equipment and control panel applications. The family includes PCB and plug-in mounting arrangements, with compatible Series 95 sockets available for suitable configurations. For an exact replacement, the complete 40.61.7.024.1321 part number should be matched to the original relay, including its contact, terminal and environmental construction.
