Why Choose the Finder 46.61.9.024.4000T Miniature Industrial Relay?
The Finder 46.61.9.024.4000T is a compact 16 A miniature industrial electromechanical relay designed for reliable electrical switching in industrial automation, railway electrical equipment and control panels. Part of the Finder 46 Series railway relay range, it features a 24 V DC coil, one changeover contact and silver-tin oxide (AgSnO2) contact material for dependable switching in appropriately rated electrical circuits.
This relay provides an effective interface between low-voltage control circuits and separate electrical loads. Its single-pole double-throw (SPDT) contact arrangement offers normally open and normally closed switching functions, allowing one control signal to operate equipment, change circuit states or provide auxiliary signalling. The 46.61T variant is specifically associated with Finder's railway-oriented relay range, making it relevant to applications requiring components selected for railway electrical environments.
With a 16 A rated contact current, a 24 V DC nominal coil and a 250 V AC rated contact voltage, the Finder 46.61.9.024.4000T combines industrial switching capability with a compact plug-in construction. Its approximately 29 × 12.4 × 32.8 mm housing supports installation in space-constrained equipment, while its removable design facilitates servicing and replacement.

Reliable Electrical Switching for Industrial Automation
Electromechanical relays such as the Finder 46.61.9.024.4000T allow industrial control systems to switch separate electrical circuits using an electromagnetic operating mechanism. When the 24 V DC coil is energised, the internal changeover contact transfers from its normally closed position to its normally open position. This enables one control signal to operate a load, change a signalling state or provide auxiliary switching within an electrical control system.
The Finder 46.61T relay configuration is intended for industrial and railway-oriented electrical applications where compact construction and dependable switching are important. Its AgSnO2 contacts and reinforced insulation support use in appropriately specified control assemblies, while the plug-in design helps simplify equipment servicing. For motors, inductive loads or circuits with high inrush currents, the relay must be selected using the relevant load-specific switching ratings rather than the resistive-load current rating alone.
