40.61.7.005.1301 Finder Miniature PCB relay 1pole 16A DC 5V

Why Choose the Finder 40.61.7.005.1301 High-Temperature PCB Power Relay?

The Finder 40.61.7.005.1301 is a miniature 16 A, 5 V DC electromechanical power relay from the Finder Series 40 range. Designed for electronic control equipment, PCB assemblies and electrical load switching, this specialist version combines a sensitive DC coil, a single changeover contact and a high-temperature, wash-tight construction.

The 40.61 relay design provides one changeover contact (1 CO / SPDT), allowing a common connection to switch between normally closed and normally open terminals. With a 16 A rated contact current and 250 V AC rated contact voltage, the relay is suitable for a variety of compatible electrical loads, including industrial control circuits, electronic appliances and automation equipment.

A key distinction of the 40.61.7.005.1301 is its .1301 configuration, which identifies a high-temperature, wash-tight variant within the Finder Series 40 ordering system. This makes it particularly relevant to electronic assemblies where elevated temperatures or specified PCB cleaning processes must be considered.

The relay also features a 5 V DC sensitive coil with a nominal consumption of 0.5 W, making it suitable for low-voltage electronic control circuits equipped with an appropriately rated relay driver.

Important: The +125 °C designation identifies the high-temperature special version; it should not be interpreted as permission to operate the relay at full electrical load continuously at that temperature. Verify the current Finder temperature-derating information, coil operating limits and complete variant-specific datasheet before use. The .1301 configuration should also be checked for its exact pin length and mounting arrangement.

High-Temperature Special Version for Demanding Electronic Assemblies

The Finder 40.61.7.005.1301 is distinguished from standard Series 40 variants by its high-temperature special construction.

Finder's Series 40 ordering system identifies the special version with code 3 as a high-temperature, wash-tight option associated with a +125 °C temperature designation.

This configuration is particularly useful when selecting components for electronic equipment exposed to elevated temperatures or manufacturing processes that place additional thermal demands on PCB-mounted components.

Applications may include industrial control assemblies, enclosed electronic equipment, appliance electronics and specialised OEM circuit boards.

Temperature suitability must always be assessed using the manufacturer's relevant operating curves and electrical ratings. Coil energisation, contact loading, ambient temperature and heat generated by neighbouring components can all affect the permissible operating conditions.

RT III Wash-Tight Construction for PCB Manufacturing

The relay features a wash-tight RT III enclosure classification, intended to provide protection during specified printed circuit board cleaning processes.

Electronic manufacturing often involves soldering and cleaning operations to remove flux residues and other contaminants. A wash-tight relay construction helps protect internal relay components during suitable manufacturing procedures.

This makes the Finder 40.61.7.005.1301 attractive for PCB assembly applications where the production process requires a relay with an appropriate enclosure classification.

RT III wash-tight classification does not mean that the relay is suitable for unrestricted exposure to water, continuous immersion or outdoor installation without a protective enclosure.

PCB cleaning, soldering and handling procedures should follow Finder's current manufacturing recommendations.

5 V DC Sensitive Coil for Electronic Control

The Finder 40.61.7.005.1301 uses a 5 V DC sensitive coil with a nominal consumption of 0.5 W.

At its nominal voltage, the coil has a resistance of approximately 50 Ω and draws approximately 100 mA.

These characteristics make the relay suitable for electronic control systems with an appropriately rated 5 V DC supply and switching driver.

In microcontroller-based systems, the relay should generally be controlled through a suitable transistor, MOSFET or relay-driver integrated circuit rather than directly from a logic output pin.

Transient suppression should also be considered when the coil is de-energised. Any suppression component must be selected with regard to the relay's required release behaviour and the characteristics of the control circuit.

16 A Changeover Contact for Electrical Load Switching

The Finder Type 40.61 uses a single 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 allows the relay to be used for:

• Switching electrical loads on or off.
• Changing between two control circuit paths.
• Providing equipment interlocking functions.
• Controlling compatible appliances and actuators.
• Providing status or alarm switching.
• Separating low-voltage control circuitry from a switched electrical circuit.

The 16 A rated contact current applies to the manufacturer's specified conditions. Loads with high inrush current, including motors, transformers, capacitive circuits and some LED drivers, require additional consideration.

For PCB-mounted applications, the printed circuit board copper tracks, terminals and protective devices must also be appropriately rated for the intended load current.

Electrical Isolation Between Coil and Contacts

The Finder Type 40.61 provides substantial electrical separation between its coil and switching contacts.

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

These characteristics support applications where low-voltage electronic control equipment must operate separate electrical circuits.

The relay's insulation characteristics must be considered as part of the complete equipment design. Appropriate PCB clearances, enclosure protection, overcurrent protection and electrical safety measures remain essential.
