40.61.7.005.1001 Finder Miniature PCB relay 1pole 16A DC 5V

Why Choose the Finder 40.61.7.005.1001 PCB Power Relay?

The Finder 40.61.7.005.1001 is a compact 16 A, 5 V DC electromechanical power relay from the Finder Series 40 range. Designed for PCB-based electrical control and power switching applications, the relay combines a high-current changeover contact with a sensitive DC coil in a space-efficient miniature housing.

Based on the Finder Type 40.61 design, this relay features one changeover contact (1 CO / SPDT), allowing a common connection to switch between normally closed and normally open terminals. Its 16 A rated contact current makes it suitable for a range of compatible electrical loads, including control circuits, automation equipment, appliances and electronic switching systems.

The 5 V DC sensitive coil allows the relay to be operated by a suitably rated low-voltage electronic control circuit. The Series 40 design also provides substantial electrical separation between the control coil and switching contacts, making it useful in equipment that requires low-voltage control of separate electrical loads.

The 40.61.7.005.1001 is a specific variant within the Series 40 family. The exact contact-material and enclosure options associated with the .1001 suffix should be checked against Finder's current product documentation before selecting it as a replacement for another 40.61 relay.

Technical note: The principal electrical ratings above are based on Finder's published Type 40.61 Series 40 specifications. The precise contact material, enclosure classification, pin length and approval status of the .1001 configuration should be verified against the manufacturer part-number documentation. When mounted in a socket, the permissible contact current may be lower than the relay's standalone 16 A rating.

5 V DC Sensitive Coil for Electronic Control Systems

The Finder 40.61.7.005.1001 uses a 5 V DC sensitive coil, allowing it to be incorporated into compatible low-voltage electronic control systems.

The sensitive DC coil version of the Series 40 is designed to reduce coil power requirements compared with higher-consumption relay configurations. With a nominal coil consumption of approximately 0.5 W, the relay can be driven using an appropriately rated electronic switching stage.

For microcontroller, PLC or embedded control applications, the relay should normally be operated through a suitable transistor, MOSFET or relay-driver circuit rather than directly from a low-current logic output.

Appropriate coil transient suppression should also be considered to protect the associated control electronics when the relay is switched off. The selected suppression arrangement must be compatible with the required relay release characteristics.

16 A Changeover Contact for Flexible Power Switching

The Type 40.61 relay features one changeover contact, commonly described as SPDT (single-pole double-throw).

In its normal, de-energised state, the common contact is connected to the normally closed terminal. When the coil receives its rated control voltage, the relay operates and transfers the common connection to the normally open terminal.

This arrangement allows the relay to perform several useful functions, including:

• Switching a load on when a control signal is applied.
• Disconnecting a circuit when the relay is energised.
• Changing between two alternative circuit paths.
• Providing an electrical interlock or control status signal.
• Operating compatible electrical loads from low-voltage electronics.

The 16 A contact rating applies under the manufacturer's specified conditions. Different load types, including motors, solenoids, transformers and LED drivers, can impose additional switching demands. The appropriate utilisation rating and inrush current must therefore be considered during circuit design.

High Electrical Isolation Between Coil and Contacts

A key feature of the Finder Series 40 relay design is its electrical separation between the low-voltage coil circuit and the switched contacts.

The Type 40.61 provides 8 mm creepage and clearance and a specified 6 kV impulse withstand voltage between coil and contacts.

These characteristics make the relay useful in electronic equipment where a low-voltage control circuit must operate a separate higher-voltage electrical load.

Electrical isolation within the relay does not replace the need for correct PCB layout, protective earthing where applicable, suitable insulation distances, overcurrent protection and compliance with the safety standards governing the complete equipment.

PCB and Socket Mounting Options

The Finder Series 40 range supports direct PCB installation and compatible plug-in socket arrangements. The Type 40.61 uses a 5 mm contact pin pitch, allowing integration into suitable printed circuit board designs.

Compatible Finder Series 95 sockets can provide additional mounting flexibility, including installation on a DIN rail when the correct socket is selected.

When choosing a mounting arrangement, engineers should verify the exact relay pin length, socket compatibility and current-carrying capability. The maximum current permitted through a socket may be lower than the standalone relay contact rating.

The .1001 suffix should be checked against Finder's ordering information to ensure the correct mounting and construction options are selected.
