40.61.6.006.4000 Finder Miniature PCB relay 1pole 16ADC

Why Choose the Finder 40.61.6.006.4000 Bistable PCB Power Relay?

The Finder 40.61.6.006.4000 is a compact and reliable 16 A bistable electromechanical power relay designed for electrical switching, industrial automation and electronic control applications. As part of the Finder 40 Series miniature PCB and plug-in relays, this model combines high-current switching capability with a single-coil latching mechanism, making it suitable for equipment manufacturers, automation engineers and electronic control system designers.

Unlike conventional monostable relays, the Finder 40.61.6.006.4000 uses a bistable operating mechanism that maintains its contact position without requiring continuous coil energisation. The relay changes state through the appropriate control pulse, reducing holding power consumption and making it particularly useful for applications requiring retained switching states.

With a 6 V nominal coil voltage, a 16 A rated contact current and a single-pole double-throw (SPDT) changeover contact, this relay provides flexible switching for electrical loads and control circuits. Its compact PCB-compatible construction and compatibility with suitable Finder 95 Series sockets enable straightforward integration into industrial equipment and electrical control assemblies.

Reliable Bistable Switching for Industrial Automation

Bistable relays such as the Finder 40.61.6.006.4000 provide an efficient method of controlling electrical circuits while minimising the need for continuous coil energisation. The latching mechanism retains the relay contact position after the switching pulse has ended, allowing the connected circuit to remain in its selected state without a continuous holding current.

The Finder 40 Series is designed for industrial automation, electrical equipment and electronic control applications requiring compact construction and dependable switching performance. The 40.61 configuration offers a higher contact current rating than many miniature signal relays, making it suitable for switching appropriately rated power and control loads.

The Finder 40.61.6.006.4000 combines a low-voltage control coil with a 16 A changeover contact, enabling switching applications in machinery, electronic equipment and control assemblies. Its PCB pin arrangement allows direct integration into circuit boards, while compatible Finder 95 Series sockets provide additional installation flexibility.

The bistable operating mechanism requires the appropriate coil drive and switching pulse arrangement. Designers should ensure that the control circuit, contact loading and any necessary protective components are selected according to the relay's electrical characteristics and the connected application.
