40.61.6.012.1000 Finder Miniature PCB relay 1pole 16ADC

Why Choose the Finder 40.61.6.012.1000 Bistable PCB Power Relay?

The Finder 40.61.6.012.1000 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 OEM manufacturers, automation engineers and electrical control system designers.

Unlike conventional monostable relays, the Finder 40.61.6.012.1000 features a bistable operating mechanism that retains its selected contact position without continuous coil energisation. The relay uses controlled SET and RESET pulses to change its switching state, reducing holding power consumption and supporting energy-efficient operation in equipment requiring maintained electrical switching.

With a 12 V AC/DC nominal coil voltage, a 16 A rated contact current and a single-pole double-throw (SPDT) changeover contact, the Finder 40.61.6.012.1000 provides flexible switching for industrial control circuits and electrical loads. Its compact construction and compatibility with suitable Finder 95 Series sockets enable straightforward integration into PCB assemblies and electrical control equipment.

Reliable Bistable Switching for Industrial Automation

Bistable electromechanical relays such as the Finder 40.61.6.012.1000 provide a practical method of switching electrical loads while reducing continuous control power requirements. Unlike conventional relays that require their coils to remain energised to maintain an operated position, a bistable relay uses a magnetic latching mechanism to retain its contact state after the control pulse has ended.

The Finder 40 Series is designed for industrial automation engineers, electronic equipment manufacturers and electrical control system designers requiring compact and dependable switching components. The 40.61 configuration offers a 16 A single changeover contact, making it suitable for applications requiring higher switching currents than those typically handled by miniature signal relays.

The Finder 40.61.6.012.1000 uses a 12 V AC/DC single-coil bistable mechanism with separate SET and RESET control operations. When the appropriate pulse is applied, the relay transfers its contact position and remains in that state until the corresponding reverse switching operation is initiated. The control circuit must provide the correct pulse arrangement and prevent simultaneous SET and RESET commands.

Its compact PCB-compatible construction enables integration into electronic control assemblies, while suitable Finder 95 Series sockets provide additional installation flexibility. The relay's electrical ratings, insulation characteristics and latching functionality make it a practical solution for industrial control, power management and automation applications.
