Why Choose the Finder 46.52.9.024.5000T Industrial Power Relay?
The Finder 46.52.9.024.5000T is a compact, reliable 8 A industrial electromechanical relay designed for electrical switching in automation systems, control panels and industrial machinery. Part of the Finder 46 Series miniature industrial relay range, this model combines a 24 V DC coil with two changeover contacts, providing flexible switching and electrical isolation for industrial control applications.
A distinguishing feature of the 46.52.9.024.5000T is its gold-plated silver-nickel (AgNi + Au) contact material. The gold-plated contact surfaces are particularly useful in applications involving low-level signals, where contact surface condition and reliable electrical continuity are important. The relay features a double-pole double-throw (DPDT / 2 CO) configuration, allowing two separate circuits to be controlled simultaneously.
With a 24 V DC nominal coil voltage, 8 A rated contact current and 250 V AC rated contact voltage, this Finder industrial relay is suitable for PLC interfaces, industrial control cabinets, signalling systems and OEM electrical equipment. Its plug-in mounting design allows straightforward installation and replacement using compatible relay sockets, while the T-suffix variant is associated with Finder's railway-oriented relay offering.

The Finder 46.52.9.024.5000T uses gold-plated silver-nickel contacts, providing an important distinction from standard AgNi relay variants. Gold plating helps maintain a stable contact surface and can improve switching reliability in appropriately designed low-level signal circuits. This makes the relay useful for industrial control, monitoring and signalling applications where dependable contact operation is important. Engineers should consider the intended switching current and voltage, as higher-energy switching can affect the gold-plated contact surface.
The relay's DPDT configuration provides two electrically separate changeover contact sets operated by a single 24 V DC coil. Energising the coil transfers both common contacts from their normally closed positions to their normally open positions; removing coil power returns them to their resting states. Combined with reinforced insulation, compact construction and plug-in mounting, this arrangement supports straightforward integration into PLC interfaces, railway-related control systems and industrial automation equipment.
