55.12.8.120.2000 Finder Miniature PCB relay 2pole 10A 120V

Why Choose the Finder 55.12.8.120.2000 Miniature Industrial Relay?

The Finder 55.12.8.120.2000 is a compact miniature industrial electromagnetic relay designed for dependable electrical switching in automation systems, industrial machinery and electronic control equipment. Part of the established Finder 55 Series, this relay features a 120 V AC nominal coil and a two-pole changeover contact arrangement (2 CO / DPDT), providing flexible control of two separate electrical circuits.

The Finder 55.12 relay family combines compact construction with printed circuit board mounting, making it suitable for electronic control assemblies and industrial equipment where installation space is limited. Its two changeover contacts provide normally open and normally closed switching functions, allowing engineers to implement control logic, signal routing and electrical load switching using a single relay.

With a 10 A nominal contact current rating associated with the 55.12 configuration, the Finder 55.12.8.120.2000 is suitable for appropriately rated industrial control applications. Its 120 V AC coil supports compatible AC-operated control systems, while its monostable electromagnetic switching mechanism provides predictable contact operation when the coil is energised or de-energised.

Key Advantages

• 120 V AC nominal coil: Suitable for compatible industrial AC control circuits.
• Two changeover contacts: Allows two separate electrical circuits to be switched simultaneously.
• 10 A nominal contact rating: Provides useful switching capacity for appropriately rated loads.
• DPDT contact arrangement: Offers normally open and normally closed connections for each pole.
• Compact PCB mounting: Supports integration into electronic control boards and industrial equipment.
• Electromagnetic switching: Provides electrical separation between the coil circuit and switched contacts.
• Monostable operation: Automatically returns contacts to their normal positions when coil power is removed.
• Finder 55 Series design: Suitable for industrial automation, OEM equipment and electrical control applications.

Reliable Two-Pole Switching for Industrial Automation

The Finder 55.12.8.120.2000 uses an electromagnetic coil to operate two separate changeover contact sets. When the appropriate 120 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 switching operation.

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

Its 10 A nominal contact rating makes the Finder 55.12 relay family suitable for a range of industrial control requirements. Actual switching capacity depends on the operating voltage, load characteristics, power factor, inrush current and switching frequency. Engineers should ensure that the connected load, PCB layout and control supply comply with the relevant Finder specifications.

The compact PCB-mounted design is particularly beneficial for industrial electronic assemblies where space efficiency and organised circuit layouts are important. By combining two changeover contacts with a 120 V AC coil, the Finder 55.12.8.120.2000 provides a practical switching solution for industrial machinery and electrical control systems.
