Compact PCB Relay Design for Electronic Equipment
The Finder 30.22.9.012.0020 is designed for applications where conventional industrial relays would occupy too much space. Its subminiature dual-in-line construction allows the relay to be integrated directly into a printed circuit board, eliminating the need for a separate DIN rail socket or panel-mounted relay assembly.
PCB-mounted relays are widely used in electronic controllers, monitoring equipment, interface circuits and compact automation systems. They allow a low-voltage control circuit to operate separate electrical contacts, providing electromechanical switching functionality within a relatively small component footprint.
The 12 V DC coil makes this model suitable for electronic systems equipped with an appropriately rated DC supply and relay-driving circuit. Designers should ensure that the control electronics can deliver the required coil current and provide appropriate transient suppression where necessary.
A distinguishing feature of the Finder 30.22.9.012.0020 is its AgNi + Au contact material. Silver nickel provides a durable electrical contact base, while the gold-plated surface is particularly useful in applications involving relatively low switching currents and signal levels.
Gold-plated contacts can help maintain reliable electrical connections in suitable low-level signal circuits. This makes the relay attractive for control interfaces, electronic monitoring equipment, instrumentation and other applications where dependable contact performance is important.
Although the relay is rated for switching currents up to 2 A, the actual permissible load depends on the voltage, load type, switching frequency and electrical characteristics of the connected circuit. Inductive loads, capacitive loads and circuits with high inrush currents require particular attention during component selection.
Wash-Tight RT III Construction for PCB Assembly
The Finder 30.22.9.012.0020 features a wash-tight RT III enclosure classification, which is useful in electronic manufacturing processes involving specified PCB cleaning operations.
This construction helps protect the relay's internal components against the ingress conditions covered by its RT III classification during appropriate assembly and cleaning procedures. It does not mean that the relay is suitable for unrestricted exposure to water, outdoor installation or continuous immersion.
For electronic equipment manufacturers, the wash-tight construction provides flexibility when incorporating the relay into automated PCB assembly processes. Cleaning methods, soldering profiles and handling procedures should always follow the manufacturer's recommendations.
