Reliable Electrical Switching with a Sensitive 24 V DC Coil

The Finder 40.61.7.024.1001 uses an electromagnetic coil to operate a single changeover contact. When the specified 24 V DC control voltage is applied, the relay energises and transfers its common contact from the normally closed terminal to the normally open terminal. Removing the coil supply allows the contacts to return to their original position.

The sensitive DC coil is designed for low-power control applications, with a nominal consumption of approximately 0.5 W. This makes the relay useful for compatible electronic control circuits and PLC interfaces where minimising coil power demand is desirable. Its 16 A changeover contact provides a separate switching path for electrical loads, subject to the applicable voltage, current and utilisation category limits.

The RT III wash-tight construction offers enhanced protection against ingress during suitable PCB cleaning processes when compared with standard flux-proof relay designs. However, wash-tight construction does not mean that the relay is intended for continuous immersion or exposed outdoor installation.

For applications involving motors, transformers, capacitive loads or LED drivers, engineers should consider starting currents, inrush currents and switching frequency rather than relying solely on the rated resistive-load current. Appropriate PCB conductor sizing, coil suppression and circuit protection are also important for dependable operation.

Typical Applications

  • Industrial automation and machinery control.
  • PLC output interfacing with compatible coil drive circuits.
  • Electrical control panels and switching assemblies.
  • PCB-based electronic control equipment.
  • Industrial signalling and indication circuits.
  • Building automation and electrical control systems.
  • Auxiliary motor control and interlocking circuits.
  • Packaging and production machinery.
  • OEM electronic and electrical assemblies.
  • General-purpose electrical load switching.
  • Control logic and changeover switching applications.
  • PCB assemblies requiring a wash-tight relay construction.
