43.41.7.009.0300 Finder Miniature PCB relay 1pole 10A DC 9V

Why Choose the Finder 43.41.7.009.0300 Low-Profile PCB Relay?

The Finder 43.41.7.009.0300 is a compact 10 A miniature electromechanical power relay designed for reliable electrical switching in electronic equipment, industrial automation and control systems. Part of the established Finder 43 Series low-profile PCB relay family, it combines a sensitive DC operating coil with a space-efficient housing for integration into electronic circuit boards and OEM equipment.

Featuring a 9 V DC sensitive operating coil and a single normally open (SPST-NO/1 NO) contact configuration, this relay enables a compatible low-voltage control circuit to switch an independent electrical load. Its electromagnetic operating mechanism provides galvanic separation between the coil and contact circuit, helping protect the control side from the switched circuit.

With a 10 A rated contact current, a 250 V AC nominal contact voltage and a 2,500 VA AC-1 switching capacity, the Finder 43.41.7.009.0300 is suitable for appropriately rated electrical loads in industrial and commercial equipment. Its silver nickel (AgNi) contacts, low-profile construction and 5 mm contact terminal pitch make it a practical choice for compact PCB-based switching applications.

Reliable Normally Open Switching for Electronic Control Systems

The Finder 43.41.7.009.0300 operates by energising its electromagnetic coil to close a normally open contact. When the coil is de-energised, the contact returns to its open position. This arrangement is particularly useful for applications where an electrical load should remain disconnected until an appropriate control signal is applied.

The 9 V DC sensitive coil enables integration into compatible electronic control systems, while the 10 A normally open contact provides switching capability for suitably rated loads. The relay's reinforced insulation, compact dimensions and PCB solder terminals support use in professional electronic equipment where reliable circuit separation and space-efficient construction are important.

Typical Applications

• Electronic control boards and printed circuit assemblies.
• Industrial automation and machinery control interfaces.
• Embedded electronic systems using compatible 9 V DC control supplies.
• Building automation and equipment switching.
• Lighting control circuits within the relay's rated capacity.
• Alarm systems and electronic switching equipment.
• Automatic doors, gates and access control systems.
• Heating, ventilation and air-conditioning control equipment.
• Vending machines and automated commercial equipment.
• OEM electronic products and compact industrial controllers.
