Why Choose the Finder 55.12.9.012.2000 Industrial PCB Relay?

The Finder 55.12.9.012.2000 is a 12 V DC industrial electromagnetic relay from the Finder Series 55 range, designed for printed circuit board mounting and general-purpose electrical switching applications. Featuring two changeover contacts (DPDT / 2 CO), this relay enables two separate electrical circuits to be controlled using a single electromagnetic coil.

The Finder 55.12.9.012.2000 combines a compact industrial relay design with a DC-operated coil and flexible changeover switching. Its contact arrangement provides normally open and normally closed connections on both poles, making it suitable for control logic, signal switching, equipment interfaces and electrical automation systems.

Designed for integration into compatible PCB assemblies, the relay is suitable for original equipment manufacture, industrial control board maintenance and replacement applications. Its 12 V DC coil makes it particularly relevant to electronic control circuits using a low-voltage DC supply.

Key Advantages

  • 12 V DC coil operation: Suitable for electronic control systems using a compatible low-voltage DC supply.
  • Dual changeover contacts: Allows two separate circuits to be switched simultaneously.
  • DPDT switching flexibility: Provides both normally open and normally closed connections on each contact pole.
  • PCB mounting design: Supports direct integration into compatible printed circuit board assemblies.
  • Electromagnetic operation: Provides mechanically operated electrical contacts controlled by an energised coil.
  • Monostable switching: Contacts return to their normal positions when the coil is de-energised.
  • Compact industrial construction: Suitable for electrical control equipment where installation space is limited.
  • Separate control and switched circuits: Enables a low-voltage control signal to operate independent electrical circuits.
  • Versatile applications: Suitable for automation, electronic equipment and auxiliary control functions.
  • Finder Series 55 compatibility: Part of an established industrial relay family with multiple coil and contact variants.

Reliable Dual Changeover Switching for 12 V DC Control Systems

The Finder 55.12.9.012.2000 industrial PCB relay uses a 12 V DC electromagnetic coil to operate two changeover contact sets. Each contact set provides a common terminal, a normally closed terminal and a normally open terminal. When the coil is energised, both common contacts transfer from their normally closed positions to their normally open positions. When coil power is removed, the relay returns to its normal state.

This arrangement allows a single control signal to operate two independent circuits, making the relay useful for auxiliary control, electrical interlocking, status switching and automation functions. The PCB mounting configuration supports installation within purpose-designed electronic assemblies.

For replacement or new equipment design, the 55.12.9.012.2000 should be matched against the required coil voltage, PCB footprint, terminal arrangement and contact load characteristics. Contact current ratings, switching voltage limits and electrical endurance must be checked against the applicable Finder technical documentation before the relay is used to switch a particular load.

Typical Applications

  • Industrial automation control boards.
  • PLC interface and auxiliary control circuits.
  • Electronic equipment switching.
  • Machinery control electronics.
  • Electrical control panel assemblies.
  • Building automation systems.
  • Equipment status indication and signalling.
  • Low-voltage DC control systems.
  • Industrial equipment maintenance and repair.
  • OEM printed circuit board assemblies.

Frequently Asked Questions

What is the Finder 55.12.9.012.2000 used for?

The Finder 55.12.9.012.2000 is an industrial PCB-mounted electromagnetic relay used for electrical switching in automation equipment, control circuits, electronic assemblies and machinery control systems.

What is the coil voltage of the Finder 55.12.9.012.2000?

The relay has a 12 V DC nominal coil voltage. It should be operated using a compatible DC control supply within the manufacturer's specified voltage limits.

What contact configuration does the Finder 55.12.9.012.2000 have?

The relay features two changeover contacts, described as DPDT, 2 CO or 2 Form C. Each pole provides common, normally open and normally closed connections.

Can the Finder 55.12.9.012.2000 switch two circuits?

Yes. Its DPDT contact arrangement enables two electrically separate circuits to be switched simultaneously when the relay coil is energised.

Is the Finder 55.12.9.012.2000 suitable for PCB mounting?

Yes. The Finder 55.12 relay type is designed for printed circuit board mounting using solder terminals. The PCB footprint must match the relay's terminal arrangement.

Is the Finder 55.12.9.012.2000 a latching relay?

No. It is a monostable electromagnetic relay, meaning its contacts return to their normal positions when the coil is de-energised.

What is the difference between Finder 55.12.9.012.2000 and 55.12.8.230.2000?

The main difference is the coil supply. The 55.12.9.012.2000 uses a 12 V DC coil, whereas the 55.12.8.230.2000 uses a 230 V AC coil. They must not be substituted without checking the control supply and all other electrical and mechanical specifications.

Can the Finder 55.12.9.012.2000 replace another Series 55 relay?

Replacement suitability depends on matching the coil voltage, contact configuration, switching ratings, PCB terminal layout and contact material. Relays from the same series are not automatically interchangeable.
