Why Choose the Finder 55.12.9.024.0001 Miniature General Purpose Relay?
The Finder 55.12.9.024.0001 is a compact 10 A miniature general purpose electromechanical relay designed for reliable electrical switching in industrial automation, electronic control equipment and machinery applications. Part of the Finder 55 Series, this relay features a 24 V DC coil, two changeover contacts and silver-nickel (AgNi) contact material for dependable switching of appropriately rated electrical loads.
The double-pole double-throw (DPDT) contact configuration provides two separate changeover circuits operated by a common electromagnetic coil. This enables one control signal to switch two circuits simultaneously, making the Finder 55.12.9.024.0001 suitable for auxiliary control, equipment signalling, electrical interlocking and PCB-based automation systems.
With a 10 A rated contact current, 250 V AC rated contact voltage and 2,500 VA AC1 switching capacity, the relay provides practical switching performance in a compact package. Its RT III wash-tight construction, PCB through-hole terminals and −40 to +85 °C operating temperature range make it particularly suitable for equipment manufacturers and electronic control system designers requiring a durable relay for printed circuit board integration.

Reliable Electrical Switching for Industrial Automation
The Finder 55.12.9.024.0001 provides reliable electromechanical switching for industrial control circuits and electronic equipment. When the 24 V DC coil is energised, both changeover contacts transfer from their normally closed positions to their normally open positions. This enables a single control signal to operate two electrically separate switching circuits, supporting auxiliary control functions, equipment signalling and electrical interlocking.
The Finder 55 Series is particularly suitable for automation engineers and OEM equipment manufacturers requiring compact, PCB-mounted relay solutions. The RT III wash-tight construction provides enhanced protection during appropriate PCB assembly and cleaning processes, while the AgNi contacts support general purpose electrical switching. For motors, inductive loads and circuits with high inrush currents, the applicable load-specific switching ratings must be checked rather than relying solely on the AC1 resistive-load rating.
Typical Applications
- Industrial automation and electronic control assemblies.
- PCB-mounted auxiliary switching circuits.
- Industrial machinery control equipment.
- Electrical interlocking and control logic applications.
- Building automation and equipment control systems.
- Heating, ventilation and air conditioning controllers.
- Equipment monitoring and status indication circuits.
- Automated production and process control equipment.
- OEM electronic control boards and industrial machinery.
- Electrical distribution and auxiliary control equipment.
- Control systems requiring wash-tight PCB relay construction.
