43.41.7.048.0001 Finder Miniature PCB relay 1pole 10A DC 48V

Why Choose the Finder 43.41.7.048.0001 Low-Profile PCB Relay?

The Finder 43.41.7.048.0001 is a compact 10 A electromechanical power relay designed for reliable switching in industrial automation, electronic control equipment and printed circuit board assemblies. Part of the established Finder 43 Series low-profile relay range, it combines a sensitive DC coil, a versatile changeover contact and reinforced electrical insulation in a space-saving housing.

Featuring a 48 V DC electromagnetic coil and a single-pole double-throw (SPDT / 1 CO) contact configuration, the relay allows a DC control circuit to operate a separate electrical load. Its changeover contact provides normally open and normally closed switching functions, making it suitable for control logic, auxiliary switching, industrial automation interfaces and electronic equipment.

With a 10 A rated contact current, 250 V AC rated contact voltage and a sensitive 250 mW coil, the Finder 43.41.7.048.0001 delivers dependable switching with low control power consumption. Its RT III wash-tight construction, reinforced coil-to-contact insulation and compact PCB mounting design make it particularly suitable for OEM electronic equipment and industrial control assemblies.

Efficient Changeover Switching with Reinforced Electrical Isolation

The Finder 43.41.7.048.0001 operates by energising a sensitive electromagnetic coil to change the position of its mechanical contacts. When the 48 V DC coil is energised, the common contact transfers from the normally closed terminal to the normally open terminal. This allows a low-power control signal to switch a separate electrical circuit while maintaining galvanic isolation between the control and load circuits.

The Finder 43.41 relay design combines low coil power consumption with reinforced electrical insulation and a compact PCB footprint. The RT III wash-tight enclosure offers additional protection during compatible PCB cleaning processes, while the SPDT contact provides flexibility for switching and control functions. Correct PCB track sizing, suitable load protection and adherence to the specified electrical ratings help ensure dependable operation.
