Why Choose the Finder 30.22.7.048.0020 Subminiature PCB Relay?
The Finder 30.22.7.048.0020 is a compact electromechanical signal relay from the Finder Series 30.22 range, designed for printed circuit board integration in electronic control and automation equipment. Its dual changeover contact arrangement offers flexible switching in applications where PCB space is limited.
Featuring a 48 V DC sensitive coil and two changeover contacts (2 CO / DPDT), this relay allows two separate circuits to be switched simultaneously through one electromagnetic operating mechanism. Its gold-plated contact arrangement supports dependable low-level signal switching in suitable electronic applications.
With its subminiature dual-in-line housing, through-hole PCB terminals and monostable operation, the Finder 30.22.7.048.0020 is suited to control boards, industrial electronics and instrumentation requiring compact relay-based switching.

Compact Signal Switching for Electronic Control Systems
The Finder 30.22.7.048.0020 uses an electromagnetic coil to operate two changeover contact sets. Applying a suitable 48 V DC control signal transfers the contacts from their normally closed positions to their normally open positions. Removing the control supply allows the relay to return to its normal state.
The compact PCB package and gold-plated contacts make the relay useful for electronic switching applications requiring two contact paths and a relatively low-power control circuit. Circuit designers should verify the manufacturer's load ratings, coil operating limits and PCB footprint before installation.
Typical Applications
- Industrial electronic control boards.
- Automation interface circuits.
- Electronic instrumentation.
- Signal routing and selection circuits.
- Control equipment with 48 V DC supplies.
- Electronic monitoring and alarm equipment.
- Compact embedded control systems.
- Printed circuit board assemblies requiring DPDT switching.

Frequently Asked Questions
What is the Finder 30.22.7.048.0020 used for?
It is a subminiature PCB signal relay used to switch electrical signals and appropriately rated control circuits in electronic and industrial automation equipment.
What coil voltage does this relay require?
The Finder 30.22.7.048.0020 has a 48 V DC nominal sensitive coil.
What does DPDT mean?
DPDT means double-pole double-throw. The relay provides two changeover contacts, each with a common, normally closed and normally open connection.
Is this a latching relay?
No. It is a monostable relay, so the contacts return to their normal positions when the coil supply is removed.
Can it be installed directly on a PCB?
Yes. The Finder 30.22.7.048.0020 is intended for through-hole PCB mounting using its pin terminals.
Is this relay suitable for low-level signals?
Its gold-plated contact arrangement is intended to support low-level signal switching. The minimum and maximum switching loads should be checked against the manufacturer's specifications.
