Finder 43.41.7.005.0300 – 43 Series PCB relays
Finder 43.41.7.005.0300 is a low-profile 10 A electromechanical PCB relay with a 5 V DC sensitive coil, one normally open contact and 5 mm contact pin pitch, designed for electronic switching and industrial control applications.
Why Choose the Finder 43.41.7.005.0300 Miniature PCB Relay?
The Finder 43.41.7.005.0300 is a compact miniature electromechanical PCB relay designed for switching and control applications in electronic equipment, industrial automation and embedded control systems. Part of the Finder 43 Series, this relay combines a low-voltage DC operating coil with a compact, low-profile construction suitable for printed circuit board assemblies.
Featuring a 5 V DC nominal coil and a single-pole changeover (SPDT/1 CO) contact configuration, the relay enables an electronic control signal to operate a separate electrical circuit. Its electromechanical switching mechanism provides galvanic separation between the control coil and the switched contacts.
The Finder 43.41.7.005.0300 is particularly suitable for electronic control boards, automation interfaces, building control equipment and OEM products where compact dimensions and reliable switching are important. Its PCB terminal arrangement allows direct integration into circuit board designs, helping reduce wiring requirements and assembly space.

- Compact miniature PCB relay for electronic switching and control applications.
- 5 V DC nominal coil suitable for compatible low-voltage control circuits.
- Single-pole changeover (SPDT/1 CO) contact arrangement for flexible switching.
- Low-profile construction supports space-efficient electronic assemblies.
- Electromechanical operation provides galvanic separation between control and load circuits.
- PCB terminals enable direct integration into electronic control boards.
- Suitable for automation equipment, control interfaces and OEM electronics.
- Finder 43 Series design supports dependable switching in compact applications.
Key Features
- Finder 43 Series miniature PCB relay.
- 43.41 relay type with one changeover contact.
- 5 V DC nominal operating coil.
- SPDT (1 CO / Form C) contact configuration.
- Monostable electromagnetic switching mechanism.
- Compact, low-profile housing for electronic assemblies.
- PCB solder terminals for permanent board installation.
- Electrical isolation between the operating coil and switching contacts.
- Suitable for switching appropriately rated AC or DC loads.
- Designed for integration into industrial and commercial electronic equipment.
Reliable Switching for Electronic Control Systems
Miniature electromechanical relays such as the Finder 43.41 provide an effective interface between electronic control signals and separate electrical loads. When the operating coil is energised, the internal electromagnetic mechanism changes the contact position, allowing a connected circuit to be switched without passing the load current through the electronic control output.
The Finder 43 Series is suited to compact PCB assemblies where installation space, electrical separation and reliable switching are important. The 5 V DC coil makes this model useful in appropriately designed low-voltage electronic control systems, while its changeover contact arrangement provides flexibility for normally open and normally closed switching functions.
Typical Applications
- Printed circuit board assemblies and electronic control modules.
- Industrial automation and machinery control interfaces.
- Embedded controllers and electronic switching circuits.
- Building automation and equipment control systems.
- Low-voltage control signal interfacing.
- Lighting and auxiliary switching circuits within the relay's rated capacity.
- Commercial and industrial electronic equipment.
- OEM control boards and automated products.
