40.61.9.005.1300 Finder Miniature PCB relay 1pole 16A DC 5V

Finder 40.61.9.005.1300 – 16 A, 5 V DC Miniature Power Relay

The Finder 40.61.9.005.1300 is a miniature electromechanical power relay from the Finder Series 40 range. Featuring a 5 V DC standard coil and a 16 A single changeover contact (1 CO / SPDT), it is designed for electrical switching in compatible electronic control systems, printed circuit board assemblies and industrial automation equipment.

The Finder Type 40.61 combines a compact housing with substantial switching capability. Its 250 V AC rated contact voltage and 4000 VA AC-1 switching capacity make it suitable for a wide range of appropriately rated electrical loads, including control equipment, appliances and industrial switching circuits.

The 5 V DC standard coil has a nominal consumption of approximately 0.65 W, enabling operation from a suitable low-voltage DC supply through an appropriately rated relay-driver circuit.

The .1300 suffix identifies a specific construction variant within the Finder Type 40.61 family. The exact variant-specific features, including contact material, terminal arrangement and enclosure classification, should be verified against Finder's current ordering documentation before the relay is specified or substituted.

Important specification note: The core Type 40.61 ratings and the 9.005 standard DC-coil data are established Series 40 specifications. The exact 40.61.9.005.1300 construction variant has not been independently verified against a current manufacturer product record. Do not assume that the .1300 suffix guarantees RT III wash-tight protection, a particular contact material, a high-temperature rating or a specific pin configuration without checking Finder's documentation.

5 V DC Standard Coil for Electronic Control Applications

The Finder 40.61.9.005.1300 uses a 5 V DC standard coil, allowing a compatible low-voltage control circuit to operate a separate electrical load.

The 9.005 coil code identifies the standard DC-coil version. Its nominal resistance is 38 Ω, with a rated coil current of approximately 130 mA at 5 V DC.

This corresponds to a nominal coil power consumption of approximately 0.65 W.

The specified coil operating range extends from approximately 3.65 to 7.5 V DC, subject to the manufacturer's conditions. A nominal 5 V DC supply should be selected and regulated appropriately for the intended installation.

In electronic control systems, the relay can be operated using a suitably rated transistor, MOSFET or dedicated relay-driver circuit.

Because the coil draws approximately 130 mA, it should not be connected directly to a microcontroller output unless that output is specifically rated to provide the required current.

Appropriate coil transient suppression should be included where necessary to protect the driver electronics when the relay is switched off.

Standard DC Coil Versus Sensitive DC Coil

Finder Series 40 relays are available with different DC-coil configurations, including standard and sensitive versions.

The 40.61.9.005.1300 uses a standard DC coil, while a comparable Type 40.61 relay with coil code 7.005 uses a sensitive DC coil.

Although both operate at a nominal 5 V DC, their electrical characteristics differ:

• Standard 5 V DC coil (9.005): Approximately 38 Ω, 130 mA and 0.65 W.
• Sensitive 5 V DC coil (7.005): Approximately 50 Ω, 100 mA and 0.5 W.

These differences can affect the relay-driver circuit, power supply capacity, thermal behaviour and coil operating characteristics.

When replacing an existing relay, the coil code must be checked rather than selecting a replacement solely by nominal voltage.

16 A Changeover Contact for Flexible Electrical Switching

The Finder Type 40.61 incorporates one changeover contact (1 CO / SPDT).

The contact arrangement provides three switching connections:

• Common (COM): The shared contact terminal.
• Normally closed (NC): Connected to common when the relay is de-energised.
• Normally open (NO): Connected to common when the relay is energised.

When the 5 V DC coil is energised, the relay transfers the common contact from the normally closed path to the normally open path.

When the coil supply is removed, the contacts return to their normal position.

This arrangement enables a single relay to provide on/off switching, changeover control, signalling and electrical interlocking functions.

The 16 A rated contact current and 4000 VA AC-1 switching capacity apply under the manufacturer's specified conditions.

Load type must be considered carefully. Motors, transformers, solenoids, capacitive circuits and LED drivers can produce substantial inrush currents or switching transients, which may reduce contact life or require a different relay configuration.

High Electrical Isolation Between Coil and Contacts

The Finder Type 40.61 provides substantial electrical separation between the low-voltage control coil and the switched contact circuit.

The standard design incorporates 8 mm creepage and clearance between coil and contacts, together with a specified 6 kV impulse withstand voltage.

These characteristics support applications where electronic control circuitry must switch a separate higher-voltage electrical load.

The complete equipment must still meet applicable electrical safety requirements, including PCB clearances, conductor ratings, protective devices and enclosure design.

Understanding the .1300 Construction Variant

The .1300 suffix forms part of Finder's complete ordering code and identifies a specific construction configuration.

Finder Series 40 relays can be supplied with different contact materials, environmental protection classifications and terminal arrangements.

Some variants are intended for standard PCB assembly, while others may provide additional protection for specified cleaning processes or different application requirements.

For the 40.61.9.005.1300, the precise meaning of the .1300 suffix should be checked against the manufacturer's current ordering information.

It is particularly important not to assume that the .1300 version is interchangeable with .1000, .1001 or other construction variants simply because the contact rating and coil voltage are the same.

Compact PCB and Socket Mounting

The Finder Type 40.61 belongs to a compact relay family designed for printed circuit boards and compatible plug-in socket installations.

The standard relay body measures approximately 29 × 12.4 × 25 mm, with a 5 mm contact pin pitch.

Selected Finder Series 95 sockets provide additional installation flexibility, including DIN rail mounting where the correct socket is used.

Before specifying a PCB footprint or socket, the exact terminal arrangement and pin dimensions associated with the .1300 construction suffix should be confirmed.

Any socket, PCB copper track, connector or terminal used with the relay must also be rated for the intended current and operating conditions.
