Reliable Miniature Power Switching for Industrial Automation
The Finder 40.61.7.024.4021 provides electrical switching through an electromagnetic mechanism operated by a 24 V DC control signal. When the coil is energised, the relay changes its contact state, allowing a compatible electrical load to be controlled independently of the low-power control circuit. When the coil supply is removed, the monostable mechanism returns the contact to its normal position.
The Finder 40 Series is widely used in industrial automation and electronic control equipment where compact dimensions, reliable switching and convenient installation are essential. The 40.61.7.024.4021 combines a sensitive DC coil with AgSnO₂ contact material and a miniature housing, making it suitable for industrial control assemblies, OEM electronics and compatible replacement applications.
For installation, the relay can be integrated into a suitable PCB design or compatible Finder relay socket. The connected load, wiring, socket and protective devices must be selected according to the applicable switching category and manufacturer's ratings. The 30 A peak current specification should not be interpreted as a continuous current rating; the relay's rated contact current is 16 A.
Typical Applications
- Industrial automation control circuits.
- Electrical control panels and relay assemblies.
- Programmable logic controller (PLC) output interfacing.
- Industrial machinery and manufacturing equipment.
- Electronic control boards and OEM equipment.
- Heating and ventilation control circuits.
- Electrical load management and auxiliary switching.
- Industrial signalling and control systems.
- Motor control auxiliary circuits within the specified ratings.
- Maintenance and replacement of compatible Finder 40 Series relay installations.
