Why Choose the Finder 30.22.7.024.0020 Subminiature PCB Relay?
The Finder 30.22.7.024.0020 is a compact 2 A subminiature electromechanical signal relay designed for printed circuit board applications. Part of the Finder Series 30.22 range, it combines two changeover contacts, low coil consumption and gold-plated contact surfaces for dependable switching of low-level electrical signals.
Featuring a 24 V DC sensitive operating coil and a DPDT (2 CO) contact configuration, this relay allows two independent switching circuits to be operated simultaneously. Its silver nickel contacts with gold plating (AgNi + Au) are particularly useful for electronic control and signal-switching applications.
The Finder 30.22.7.024.0020 features a 200 mW coil, a standard dual-in-line (DIL) package and through-hole PCB terminals. Its RT III wash-tight construction supports integration into electronic assemblies where compact dimensions, low control power and reliable signal switching are important.

Reliable Low-Level Signal Switching for Electronic Circuits
The Finder 30.22.7.024.0020 operates through a sensitive 24 V DC electromagnetic coil. When energised, the relay transfers both changeover contacts from their normally closed paths to their normally open paths. When coil power is removed, the contacts return to their normal positions, providing straightforward monostable switching.
The relay's gold-plated contacts support switching of low-level electrical signals, while the 200 mW coil and compact DIL construction make it useful in electronic control assemblies. Its RT III wash-tight enclosure supports suitable PCB manufacturing and cleaning processes, subject to the manufacturer's handling instructions.
Typical Applications
- Electronic control circuit boards.
- Industrial signal switching and interface circuits.
- Audio and Hi-Fi electronic equipment.
- Printers and office electronic equipment.
- Medical and dental electronic equipment.
- Door and gate control systems.
- Hoists and cranes control electronics.
- Compact electronic automation assemblies.
