Reliable Signal Switching for Electronic Control Systems
Subminiature PCB relays such as the Finder 30.22.7.005.0020 provide electrical isolation between a low-voltage control circuit and the circuits being switched. When the 5 V DC coil is energised, the relay's electromagnetic mechanism transfers its two changeover contacts from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their original state.
The Finder Series 30.22 is particularly suited to electronic equipment requiring compact dimensions, low coil power consumption and reliable low-level signal switching. The gold-plated silver nickel contacts help maintain dependable electrical contact performance in sensitive signal circuits, while the DPDT configuration provides flexibility for switching, changeover and control applications.
Its RT III wash-tight construction offers protection during suitable printed circuit board cleaning processes, making the relay practical for electronic manufacturing and assembly. The compact DIL package and through-hole mounting arrangement support integration into densely populated PCBs used in industrial automation, communications equipment and electronic control systems.
