40.61.8.048.1000 Finder Miniature PCB relay 1pole 16A 48V

Why Choose the Finder 40.61.8.048.1000 Miniature Power Relay?

The Finder 40.61.8.048.1000 is a compact 16 A miniature electromagnetic power relay featuring a 48 V AC operating coil and a single changeover contact. Part of the established Finder 40 Series, this relay is designed for reliable electrical switching in industrial automation, machinery, electrical control panels and electronic equipment.

Featuring a single-pole double-throw (SPDT / 1 Form C) contact arrangement, the Finder 40.61.8.048.1000 provides both normally open and normally closed switching paths. Its silver-nickel (AgNi) contacts, 250 V AC rated contact voltage and 4,000 VA AC1 switching capacity make it suitable for a wide range of appropriately rated electrical loads.

The relay incorporates reinforced insulation between its coil and contact circuits, with 8 mm creepage and clearance distances and a 6 kV impulse withstand rating. Its compact construction and PCB/plug-in terminal arrangement allow integration into suitable electronic assemblies and compatible Finder 95 Series relay sockets.

Reliable 16 A Changeover Switching for Industrial Control

The Finder 40.61.8.048.1000 operates through a 48 V AC electromagnetic coil. When the coil is energised, the common contact transfers from the normally closed terminal to the normally open terminal. When the coil supply is removed, the relay returns to its normal position, providing conventional non-latching operation.

The SPDT contact configuration allows the relay to switch between two electrical paths. This is useful for auxiliary control, equipment sequencing, alarm signalling, electrical interlocking and other applications requiring a changeover function rather than a simple normally open output.

Its 16 A contact rating and 4,000 VA AC1 switching capacity make it suitable for appropriately rated resistive loads. The relay also has a specified 1,000 VA AC15 capacity at 230 V AC and a 0.55 kW single-phase motor rating, allowing selection for certain inductive and motor-control applications.

The relay's silver-nickel (AgNi) contact material provides a cadmium-free switching solution. The .1000 suffix identifies the AgNi contact version with a standard changeover circuit, standard pin arrangement and standard environmental protection.

Electrical isolation is a significant feature of the Finder 40.61 family. The relay provides reinforced insulation between coil and contacts, including 8 mm creepage and clearance distances, 4,000 V AC dielectric strength and a 6 kV impulse withstand rating. These characteristics support integration into appropriately designed industrial and electronic equipment.

The 5.2 mm terminal pins allow direct PCB installation or use with compatible Finder 95 Series sockets. Socket mounting can simplify relay replacement and maintenance, although the permissible current of the complete assembly must be checked because some Finder socket combinations have a lower current rating than the relay itself.

With a compact housing measuring approximately 29 × 12.4 × 25 mm, the relay is suitable for equipment where PCB space and enclosure dimensions are important. Its RT II flux-proof construction also supports appropriate PCB assembly processes.
