40.61.8.120.1300 Finder Miniature PCB relay 1pole 16A 120V

Why Choose the Finder 40.61.8.120.1300 Miniature Power Relay?

The Finder 40.61.8.120.1300 is a miniature electromechanical power relay from the Finder 40 Series, featuring a 120 V AC coil and a 16 A single changeover contact. Designed for electrical control and industrial automation applications, this relay enables an AC control signal to operate a separate electrical load circuit.

The Finder 40.61 relay configuration provides a single-pole double-throw (SPDT) contact arrangement, offering both normally open and normally closed switching functions. This makes the relay suitable for control panels, OEM machinery, electrical equipment and automation systems requiring dependable electromechanical switching.

With its compact construction, 250 V AC rated switching voltage and PCB-compatible design, the Finder 40.61.8.120.1300 provides a practical solution for integrating power switching into electrical assemblies. The 40 Series platform also supports compatible Finder relay sockets, allowing engineers to select installation arrangements appropriate to their equipment.

Reliable AC-Controlled Switching for Industrial Automation

The Finder 40.61.8.120.1300 provides an effective interface between 120 V AC control circuits and electrical load switching applications. When the relay coil is energised, its changeover contact transfers from the normally closed position to the normally open position. When the coil is de-energised, the contact returns to its normal state.

This switching arrangement is particularly useful in industrial control panels and OEM equipment where an AC control supply must operate auxiliary circuits, signalling equipment or appropriately rated electrical loads. The 16 A contact rating provides flexibility for suitable switching duties, while the miniature relay format helps conserve installation space.

The Finder 40 Series is designed for both direct PCB integration and compatible socket-based installation. Socket mounting can simplify relay replacement and maintenance, while PCB mounting supports compact electronic assemblies and production equipment.

When switching motors, inductive equipment or loads with high inrush currents, engineers should evaluate the applicable utilisation category and contact ratings rather than relying solely on the resistive AC1 rating. Appropriate circuit protection, contact suppression and installation practices should be used to maintain dependable operation.

Typical Applications

• Industrial automation and machinery control.
• 120 V AC control circuits.
• Electrical control panels and relay interfaces.
• OEM electrical and electronic equipment.
• PCB-mounted power switching circuits.
• Auxiliary switching for contactors and control equipment.
• Building automation and electrical equipment control.
• Industrial monitoring and signalling circuits.
• Automated lighting and electrical load switching.
• Equipment control and power distribution auxiliaries.
