40.61.9.009.1300 Finder Miniature PCB relay 1pole 16A DC 9V

Why Choose the Finder 40.61.9.009.1300 Miniature Power Relay?

The Finder 40.61.9.009.1300 is a compact 16 A miniature electromechanical power relay from the Finder Series 40 range, designed for industrial automation, electronic control systems and electrical switching applications. Featuring a 9 V DC standard coil and one changeover contact (1 CO / SPDT), this relay provides an effective interface between low-voltage control electronics and compatible electrical loads.

With a nominal coil consumption of 0.65 W, the Finder 40.61.9.009.1300 is suitable for equipment using a regulated 9 V DC control supply. Its changeover contact arrangement provides both normally open and normally closed switching functions, allowing a single relay to control alternative circuit paths.

The Finder 40.61 family combines 16 A rated contact current, 250 V AC rated contact voltage and compact construction suitable for printed circuit board and compatible socket-based installations. This makes the relay a practical choice for equipment manufacturers, electrical engineers and maintenance professionals requiring dependable electromechanical switching in space-conscious designs.

Reliable 9 V DC Switching for Industrial Automation and Electronic Equipment

The Finder 40.61.9.009.1300 provides an electromechanical interface between a 9 V DC control circuit and an electrically isolated switching contact. When the relay coil is energised, the common contact transfers from its normally closed terminal to its normally open terminal. Removing the coil supply allows the relay to return to its original contact position.

This monostable switching arrangement is useful in control systems where the electrical output must follow the state of an input signal. Typical functions include auxiliary circuit switching, equipment control, status indication and electrical interlocking within appropriately designed systems.

The relay uses a standard 9 V DC coil with a nominal resistance of 125 Ω and a nominal operating current of approximately 72 mA. Its 0.65 W coil consumption allows operation from suitably rated electronic drivers, although the controlling circuit must be capable of supplying the required energising current.

The specified standard DC coil operating range is approximately 6.6–13.5 V DC under the relevant manufacturer conditions. The nominal 9 V DC supply remains the intended operating voltage, and actual permissible limits depend on ambient temperature and duty conditions.

With a 16 A rated contact current, the Finder 40.61 relay is capable of switching compatible electrical loads. The Series 40 contact specification includes a 4,000 VA AC-1 resistive load rating and a 750 VA AC-15 rating at 230 V AC. These values relate to different load categories and should not be treated as interchangeable.

Loads such as motors, transformers, solenoids, capacitors and LED drivers may produce high inrush currents or other demanding switching conditions. For these applications, relay selection should be based on the manufacturer's applicable contact ratings, electrical endurance information and the characteristics of the actual load.

The relay also provides electrical separation between the coil and contact circuits, with the Series 40 design offering 6 kV impulse insulation and 8 mm clearance and creepage distance. These characteristics support use in appropriately designed control equipment requiring insulation coordination between circuits.

Its compact construction makes the Finder 40.61.9.009.1300 suitable for electronic assemblies where installation space is limited. The Series 40 family supports direct PCB mounting and compatible Finder Series 95 sockets, allowing designers to select an appropriate mounting arrangement for their equipment.

For maintenance or replacement, the complete 40.61.9.009.1300 ordering code should be checked. Similar Finder 40.61 relays may use different coil technologies, contact materials, terminal arrangements or environmental protection options. Matching only the coil voltage and current rating is not sufficient to establish full interchangeability.
