Finder 43.41.7.024.4000 Relé de potência miniaturizado para PCB 24 V DC 16 A SPDT

Switching high-current loads on a printed circuit board often means choosing between a bulky relay and a compact one that can still handle the job. The Finder 43.41.7.024.4000 solves that by packing a 16 A SPDT contact into a miniature PCB-mount package, driven by a low-power 24 V DC coil.

Who is it for

Engineers and technicians designing control panels, HVAC systems, or industrial automation who need a reliable PCB relay for switching heaters, motors, or lighting loads up to 16 A. It is also suitable for replacing existing Finder 43 series relays in service and maintenance.

Tips

When soldering, follow the recommended PCB footprint and avoid excessive heat to preserve the flux-proof seal. For inductive loads, consider adding a suppression diode or varistor across the contacts to extend relay life.
