Its low profile height and .100" grid spaced terminals make it ideal for applications where extreme packaging density and/or close PC board spacing are required. The RF180 design has been optimized for use in RF attenuators, RF switch matrices, and other applications requiring magnetic latching, high isolation, low insertion loss and low VSWR. Unique construction features and manufacturing techniques provide high reliability and excellent robustness to environmental extremes. • All welded construction. • Unique uniframe design provides high magnetic efficiency and mechanical rigidity. • High force/mass ratios for resistance to shock and vibration. • Advanced cleaning techniques provide maximum assurance of internal cleanliness. • Gold-plated precious metal alloy contacts ensure reliable d.c. switching from dry-circuit to 1/4 amp, as well as low and stable insertion loss in RF applications. The RF180 relay is ideally suited for applications where power dissipation must be minimized. The relays can be operated with a short-duration coil voltage pulse. After the contacts have transferred, no coil power is required. The magnetic-latching feature of the RF180 provides a nonvolatile memory capability, since the relays will not reset upon removal of coil power. PRINCIPLE OF OPERATION Energizing Coil A produces a magnetic field opposing the magnetic field of the permanent magnet in Circuit A. As the net holding force decreases, the attractive force in the air gap of Circuit B, which also results from the magnetic field of the permanent magnet, becomes great enough to break the armature free of Core A, and snap it into a closed position against Core B. The armature remains in this position upon removal of power from Coil A, but will snap back into position A upon energizing Coil B. Since operation depends upon cancellation of a magnetic field, it is necessary to apply the correct polarity to the relay coils as indicated on the relay schematic. When latching relays are installed in equipment, the latch and reset coils should not be pulsed simultaneously. Coils should not be pulsed with less than rated coil voltage and the pulse width should be a minimum of three times the specified operate time of the relay. If these conditions are not followed, it is possible for the relay to be in the magnetic neutral position.
