40.61.7.014.1000 Finder Miniature PCB relay 1pole 16A DC 14V

Why Choose the Finder 40.61.7.014.1000 PCB Power Relay?

The Finder 40.61.7.014.1000 is a compact 16 A, 14 V DC miniature power relay from the Finder Series 40 range. Designed for reliable electromechanical switching in electronic control equipment, PCB assemblies and industrial automation systems, this relay combines a sensitive DC coil with a high-current changeover contact.

Featuring one changeover contact (1 CO / SPDT), the Finder 40.61.7.014.1000 provides both normally open and normally closed switching functions. Its 16 A rated contact current and 250 V AC rated contact voltage make it suitable for a wide range of compatible electrical loads, including control circuits, electronic appliances and power-switching applications.

The relay uses a 14 V DC sensitive coil with a nominal consumption of approximately 0.5 W. This makes it suitable for electronic systems with a compatible DC supply and an appropriately rated relay-driver circuit.

The .1000 configuration identifies a wash-tight version of the Type 40.61 relay with standard contact material. Its RT III wash-tight construction supports specified printed circuit board cleaning processes, making it useful for electronic manufacturing and OEM equipment assembly.

Important: Electrical ratings are subject to load type, ambient temperature, mounting arrangement and the manufacturer's operating conditions. The 16 A rating must not be applied indiscriminately to motors, capacitive loads, LED drivers or other high-inrush equipment. The maximum switching voltage is not a continuous load rating. Verify the current Finder documentation and socket ratings before installation.

14 V DC Sensitive Coil for Low-Power Control

The Finder 40.61.7.014.1000 uses a 14 V DC sensitive coil, providing electromechanical switching from a compatible low-voltage DC control supply.

Its nominal coil resistance of 400 Ω results in a nominal current of approximately 35 mA at 14 V DC. This corresponds to a coil power consumption of approximately 0.49 W.

The specified sensitive-coil operating range extends from approximately 11.2 to 21 V DC, subject to the manufacturer's conditions. The control supply must be selected to ensure reliable operation throughout the equipment's intended temperature and voltage range.

In electronic control systems, the relay can be operated through an appropriately rated transistor, MOSFET or relay-driver circuit. Direct connection to a microcontroller output should not be assumed suitable without checking the output's current capability.

Coil transient suppression should be considered to protect the driving electronics when the relay is switched off. The suppression method must be compatible with the required release time and system operation.

16 A Changeover Contact for Flexible Power Switching

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

The contact arrangement consists of a common terminal, a normally closed terminal and a normally open terminal. When the coil is energised, the common connection transfers from the normally closed path to the normally open path.

This arrangement enables the relay to perform several useful functions:

• Switching compatible electrical loads on and off.
• Changing between two alternative circuit paths.
• Providing control interlocking functions.
• Operating compatible appliances and actuators.
• Switching status and alarm circuits.
• Controlling a separate electrical load from low-voltage electronics.

The relay has a 16 A rated contact current and a 4000 VA AC-1 switching capacity. These ratings apply to the manufacturer's specified conditions and must be interpreted alongside the connected load's electrical characteristics.

Inductive loads, motors, transformers and capacitive equipment can produce substantially different switching demands from resistive loads. Contact life and permissible current may therefore be reduced depending on the application.

Silver Cadmium Oxide Contacts for Power Switching

The 40.61.7.014.1000 uses the standard silver cadmium oxide (AgCdO) contact material specified for the Finder Type 40.61 configuration.

AgCdO contacts have historically been used in power-switching relays because of their resistance to contact welding and suitability for certain demanding electrical loads.

However, cadmium-containing contact materials are subject to environmental and regulatory restrictions. Designers should check the current product compliance documentation and any applicable exemptions before specifying the relay for new equipment.

Where cadmium-free contact material is required, an alternative Finder Series 40 configuration may be more appropriate, subject to equivalent electrical and mechanical ratings.

RT III Wash-Tight Construction for PCB Assembly

The .1000 version uses RT III wash-tight construction, providing protection during specified printed circuit board cleaning processes.

During electronic manufacturing, PCB assemblies may undergo soldering and cleaning operations to remove flux residues and manufacturing contaminants. A wash-tight relay can help protect internal components during suitable cleaning procedures.

This makes the Finder 40.61.7.014.1000 suitable for OEM electronic assemblies where the production process requires a relay with an appropriate enclosure classification.

RT III classification does not mean the relay is waterproof or suitable for continuous exposure to liquids. PCB washing, soldering and handling procedures must follow Finder's recommendations.

High Electrical Isolation Between Coil and Contacts

The Finder Type 40.61 provides substantial electrical separation between its low-voltage coil and switched contact circuits.

The relay design incorporates 8 mm creepage and clearance and a specified 6 kV impulse withstand voltage between coil and contacts.

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

The complete equipment must still meet all relevant insulation, PCB layout, protective earthing and electrical safety requirements.

PCB and Socket Mounting Flexibility

The Finder 40.61.7.014.1000 is designed for installation in compatible printed circuit board assemblies and suitable relay socket arrangements.

The Type 40.61 uses a 5 mm contact pin pitch, allowing integration into correctly designed PCB layouts.

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

When selecting a socket, the exact pin arrangement, contact current rating and environmental suitability must be checked. A socket may have a lower permissible current rating than the relay itself.
