40.51.9.024.5300 Finder Miniature PCB relay 1pole 10A DC 24V
Finder 40.51.9.024.5300 is a miniature electromagnetic PCB relay with a 24 V DC coil, one normally open 10 A contact and gold-plated AgNi contact material.
Why Choose the Finder 40.51.9.024.5300 Miniature PCB Relay?
The Finder 40.51.9.024.5300 is a compact miniature electromagnetic PCB relay designed for reliable switching in industrial control, automation and electronic equipment. Part of the proven Finder 40 Series, this monostable relay combines a 24 V DC coil with a single normally open contact rated at 10 A.
Its AgNi contact with gold plating supports dependable switching in applications requiring a high-quality contact interface. The single-pole normally open configuration closes the output circuit when the coil is energised, making the relay suitable for control boards, interface circuits and automated equipment.
The 40.51.9.024.5300 features through-hole terminals and 5 mm pinning for direct PCB installation. Its compact enclosure helps conserve board space while providing galvanic isolation between the low-voltage control circuit and the switched load.

Reliable Switching for Electronic Control Systems
Electromagnetic relays allow a low-voltage control signal to switch a separate electrical circuit. Applying 24 V DC to the coil of the Finder 40.51.9.024.5300 energises the relay and closes its normally open contact, allowing the connected load circuit to operate.
The compact Finder 40 Series format makes this relay well suited to printed circuit boards where installation space is limited. Its combination of a 10 A contact rating and gold-plated AgNi contact supports reliable use in industrial controls, interface modules and electronic equipment.
Typical Applications
- Industrial automation and control equipment.
- Printed circuit boards and electronic assemblies.
- PLC interface and output circuits.
- Control panels and machine controllers.
- Heating, ventilation and building control systems.
- Lighting and auxiliary load switching.
