55.12.8.110.2000 Finder Miniature PCB relay 2pole 10A 110V

Why Choose the Finder 55.12.8.110.2000 Miniature Industrial Relay?

The Finder 55.12.8.110.2000 is a versatile miniature industrial electromagnetic relay from the established Finder 55 Series, designed for electrical switching, automation and control applications. Featuring a 110 V AC coil and a two-pole changeover contact arrangement (2 CO / DPDT), this relay provides a practical solution for switching two independent circuits from a common control signal.

The Finder 55.12 relay family is designed for printed circuit board mounting, making it suitable for electronic control assemblies, industrial equipment and OEM applications. Its compact construction allows engineers to incorporate dependable electromechanical switching into control systems where installation space and circuit flexibility are important.

With a 10 A nominal contact current rating associated with the Finder 55.12 configuration, the 55.12.8.110.2000 is suitable for a variety of appropriately rated control and switching loads. The relay's two changeover contacts provide normally open and normally closed connections for each pole, supporting flexible control circuit arrangements in industrial machinery and electrical equipment.

Key Advantages

• 110 V AC coil: Suitable for compatible industrial AC control circuits.
• Two changeover contacts: Allows two separate circuits to be switched simultaneously.

Reliable Two-Pole Switching for Industrial Automation

The Finder 55.12.8.110.2000 uses an electromagnetic coil to operate two changeover contact sets. When the appropriate 110 V AC control voltage is applied, the relay changes the position of both contacts. When the coil is de-energised, the contacts return to their normal positions, providing conventional monostable relay operation.

The DPDT contact arrangement offers greater circuit flexibility than a single-pole relay. Each pole provides a common connection that switches between normally closed and normally open terminals, allowing the relay to control two circuits through one coil. This arrangement is useful for equipment interfacing, control logic, signalling and electrical switching functions.

Its 10 A nominal contact rating makes the Finder 55.12 relay family suitable for a range of control applications. However, actual switching capacity depends on the applied voltage, load characteristics, power factor, inrush current and switching frequency. For reliable operation, engineers should select suitable contact protection and ensure that the PCB layout, coil supply and connected loads meet the relevant Finder specifications.
