40.51.9.024.2003 Finder Miniature PCB relay 1pole 10A DC 24V

Why Choose the Finder 40.51.9.024.2003 PCB Relay?

The Finder 40.51.9.024.2003 is a compact and dependable electromechanical PCB relay designed for switching electrical loads in industrial controls, automation equipment and electronic assemblies. As part of the established Finder Series 40 relay range, it combines a high-capacity contact system with a sensitive DC coil and a space-efficient enclosure.

This relay features a single changeover contact, providing normally open and normally closed switching functions for flexible circuit design. Its AgCdO contact material supports dependable switching of general-purpose and inductive loads, while the RT III wash-tight, high-temperature construction protects the internal mechanism during compatible PCB cleaning processes and permits operation at elevated ambient temperatures.

With a 24 V DC coil, a contact rating of up to 12 A when PCB-mounted and a 5.2 mm pin length, the 40.51.9.024.2003 is suitable for industrial controllers, machinery interfaces and electronic equipment requiring dependable load switching in demanding environments.

Reliable Switching for Industrial Control Systems

Electromechanical relays such as the Finder 40.51 provide galvanic separation between a control circuit and the connected load. Applying the rated voltage to the coil transfers the changeover contact between its normally closed and normally open states, enabling machinery, lighting, heating equipment and other electrical loads to be controlled by an automation system.

The Series 40 platform is engineered for PCB and socket applications where compact dimensions, high switching capacity and dependable isolation are required. The wash-tight, high-temperature enclosure of this variant supports demanding manufacturing processes and operation in elevated-temperature environments.

Typical Applications

• Industrial control panels and automation equipment.
• Programmable controller output interfaces.
• Electronic circuit boards and control modules.
• Heating, ventilation and air-conditioning controls.
• Lighting and building automation systems.
• Equipment operating in elevated-temperature environments.
