The LP-series of miniature Reed Relays offers the ideal solution for high density, high-frequency switching. Versions with 1 form A or 1 form C switch and co-axial screen are available. With a co-axial screen the LP-series is capable of switching signals up to UHF-range. Using only the highest reliability Reed Switches ensuring long life when switching low level signals, the series includes a high power mercury wetted option. Typical applications for which the LP-series would be appropriate include RF communications, video switching and ATE.

Characteristics:

• Sealed with epoxy-resin
• Magnetic screen
• Highest reliability
• Smallest housing
