Why Choose the Finder 30.22.9.005.0020 Subminiature PCB Signal Relay?
The Finder 30.22.9.005.0020 is a compact 2 A subminiature electromechanical signal relay from the Finder 30 Series. Designed for printed circuit board applications, it combines a sensitive 5 V DC coil with a versatile two-pole changeover (2 CO / DPDT) contact arrangement.
Its industry-standard dual in-line (DIL) package makes the Finder 30.22 an excellent choice for electronic control boards, industrial automation interfaces, instrumentation and low-power switching circuits. The relay's gold-clad silver nickel (AgNi + Au) contacts support low-level signal switching, while its compact construction helps conserve valuable PCB space.
The 0020 configuration belongs to the Finder 30.22 PCB relay family, which features RT III wash-tight environmental protection, low coil power consumption and through-hole solder terminals. These characteristics make it particularly suitable for OEM electronics, control modules and maintenance of compatible electronic assemblies.

Sensitive 5 V DC Switching for Compact Electronic Control Systems
The Finder 30.22.9.005.0020 uses a sensitive electromagnetic coil to operate two independent changeover contact sets. When the 5 V DC coil is energised, each common contact transfers from its normally closed connection to its normally open connection. When the coil supply is removed, the contacts return to their normal positions.
The DPDT configuration enables two circuits to be switched simultaneously using a single control signal. This makes the relay suitable for signal routing, control circuit changeover, electronic interlocking and low-power load switching in appropriately designed electronic equipment.
With gold-clad AgNi contacts and a compact DIL package, the Finder 30.22 relay family is particularly useful where low-level switching performance and PCB space efficiency are important. The RT III wash-tight construction also supports suitable PCB assembly and cleaning processes, provided the manufacturer's processing instructions are followed.
The relay is intended for signal and low-power switching rather than high-current power distribution. Contact ratings must be assessed against the actual AC or DC load, and the PCB layout must provide appropriate electrical clearances, conductor capacity and protection.

Frequently Asked Questions
What is the Finder 30.22.9.005.0020 used for?
The Finder 30.22.9.005.0020 is a subminiature PCB signal relay designed for low-power electrical switching in electronic control boards, industrial automation interfaces, instrumentation and other compact electronic equipment.
What coil voltage does the Finder 30.22.9.005.0020 require?
The relay requires a 5 V DC nominal coil supply. Its nominal coil consumption is approximately 200 mW, corresponding to a nominal coil current of approximately 40 mA.
What is the contact configuration of the Finder 30.22.9.005.0020?
The relay features two changeover contacts (2 CO / DPDT). Each pole provides common, normally closed and normally open connections, allowing two separate circuits to change switching state when the coil is energised.
What is the switching current rating of the Finder 30.22 relay?
The Finder 30.22 relay family has a 2 A rated contact current and a maximum peak current of 3 A. The allowable switching load depends on voltage, load characteristics and the manufacturer's applicable ratings.
What does RT III wash-tight protection mean?
RT III identifies a sealed relay construction intended to withstand suitable PCB washing processes. It does not mean the relay is suitable for unrestricted outdoor exposure, immersion or operation in every wet environment.
How is the Finder 30.22.9.005.0020 mounted?
The relay is designed for through-hole PCB mounting using solder pins in a compact dual in-line package. The circuit board footprint should be checked against the manufacturer's dimensional drawing before installation.
