Why Choose the Finder 30.22.9.006.0020 Subminiature PCB Signal Relay?
The Finder 30.22.9.006.0020 is a compact 2 A subminiature electromechanical signal relay designed for reliable switching in electronic control circuits, industrial automation equipment and printed circuit board assemblies. Part of the Finder 30 Series, this miniature relay combines a sensitive 6 V DC coil with two changeover contacts in an industry-standard dual in-line (DIL) package.
Featuring a 2 CO (DPDT) contact configuration, the Finder 30.22.9.006.0020 allows two independent electrical circuits to switch between normally closed and normally open connections using a single control signal. Its silver nickel contacts with gold cladding (AgNi + Au) provide excellent suitability for appropriately rated low-level signal switching and electronic control applications.
The relay also features RT III wash-tight environmental protection, through-hole PCB mounting and a compact body measuring approximately 20.3 × 10.1 × 11.4 mm. With its low-power DC coil and miniature construction, the Finder 30.22.9.006.0020 is a practical choice for OEM electronic assemblies, instrumentation, automation interfaces and maintenance of compatible circuit boards.

Reliable 6 V DC Signal Switching for Compact Electronic Systems
The Finder 30.22.9.006.0020 operates using an electromagnetic coil to control two independent changeover contact sets. When the 6 V DC coil is energised, each common contact transfers from its normally closed connection to its normally open connection. Removing the coil supply allows the contacts to return to their normal positions.
This DPDT switching arrangement provides flexibility for signal routing, electrical changeover functions and auxiliary control circuits. Because both poles are operated by the same coil, two separate circuits can respond simultaneously to a single electronic control signal.
The relay's AgNi + Au contact material is particularly beneficial for low-level switching applications. Gold cladding helps maintain suitable contact characteristics when switching small signals, making the relay useful in instrumentation, monitoring equipment and electronic interfaces where conventional high-current power relays may be unnecessarily large.
Its RT III wash-tight enclosure also supports suitable PCB assembly processes, including controlled board cleaning. However, RT III protection does not make the relay suitable for unrestricted outdoor exposure or immersion. Electrical ratings, PCB clearances and the complete manufacturer's part-number configuration should always be checked before installation.
