55.34.8.012.2040 Finder Miniature plugin relay 4 pole 7A 12V.
The Finder 55.34.8.012.2040 is a compact and reliable 12 V AC electromagnetic plug-in relay designed for industrial automation, electrical control panels and general-purpose switching applications. As part of the established Finder 55 Series, this relay features four changeover contacts (4PDT) with a rated contact current of 7 A, providing versatile switching capabilities for industrial control circuits.
Designed for dependable operation and straightforward integration, the Finder 55.34.8.012.2040 incorporates silver cadmium oxide (AgCdO) contacts for electrical switching applications. Its four independent changeover contact sets allow multiple circuits to be controlled simultaneously from a single relay coil, making it suitable for control logic, signalling, interlocking and automation equipment.
With a 12 V AC coil operating at 50/60 Hz, a 7 A contact rating and a compact plug-in construction, this relay is well suited to electrical control cabinets and machinery installations. Its socket-mounted design supports convenient installation and replacement using compatible Finder relay sockets.
Electromagnetic relays such as the Finder 55.34.8.012.2040 provide electrically operated switching between control circuits and connected equipment. When the 12 V AC coil is energised, the relay actuates its four changeover contact sets, allowing multiple electrical circuits to be switched simultaneously. When the coil is de-energised, the contacts return to their normal positions.
The 4PDT contact arrangement provides flexibility for industrial control applications requiring several switching functions from a single control signal. Its AgCdO contacts and socket-mounted construction make the relay suitable for machine control, interlocking, signalling and electrical automation systems. The Finder 55 Series is designed to support reliable operation while simplifying control panel assembly and maintenance.
