43.41.7.018.0001 Finder Miniature PCB relay 1pole 10A DC 18V

Why Choose the Finder 43.41.7.018.0001 Low-Profile PCB Power Relay?

The Finder 43.41.7.018.0001 is a compact 10 A low-profile electromechanical PCB relay designed for electrical switching in industrial automation, electronic control equipment and printed circuit board assemblies. Part of the established Finder 43 Series, it combines a sensitive 18 V DC coil with a versatile single-pole changeover contact arrangement.

Featuring one changeover contact (1 CO / SPDT), the Finder 43.41 platform allows an electrical circuit to switch between normally closed and normally open connections. Its 10 A rated contact current makes it suitable for appropriately rated power and control applications, while its compact, low-profile construction helps conserve space inside electronic equipment.

The relay incorporates a 250 mW sensitive DC coil, reinforced coil-to-contact insulation and a PCB terminal arrangement with 3.2 mm contact pin spacing. The full 43.41.7.018.0001 part number identifies a specific manufacturer configuration; its variant-specific contact material and environmental protection should be confirmed against current Finder documentation before final component selection.

Sensitive 18 V DC Changeover Switching for Industrial Electronics

The Finder 43.41.7.018.0001 operates using an electromagnetic coil to control a single changeover contact. When the 18 V DC coil is energised, the common contact transfers from its normally closed connection to its normally open connection. When coil power is removed, the contact returns to its original position.

This SPDT switching arrangement provides flexibility for electrical control systems requiring alternative switching paths. It can be used for auxiliary control, load selection, interlocking and switching functions where the connected load remains within the relay's specified electrical ratings.

The sensitive 250 mW DC coil is useful in electronic control applications where power consumption matters. At its nominal 18 V DC supply, the coil draws approximately 13.8 mA, making it suitable for control circuitry designed to provide the required drive current and switching protection.

The Finder 43.41 relay platform also provides reinforced insulation between the coil and contacts, with a specified 6 kV impulse withstand voltage. These characteristics support electrical separation in appropriately designed equipment, although overall product safety depends on the complete PCB layout, enclosure, insulation system and applicable installation standards.
