Ultra-High Density 5mm2 TM Reed Relays

Three switch types are available. A general purpose sputtered ruthenium switch rated at 15 W, 1A (3 & 5 V versions) or 20 W, 1A (12 V versions), a low level sputtered ruthenium switch rated at 10 W, 0.5 A, and a Rhodium changeover switch rated at 2 W, 0.1 A.
Mu-metal, due to its high permeability and low magnetic remanence is used to provide magnetic screening. This eliminates problems that would otherwise occur due to magnetic interaction. Interaction is usually measured as a percentage increase in the voltage required to operate a relay when two additional relays, stacked one each side, are themselves operated.
An unscreened device mounted on this pitch would have an interaction figure of around 40%. Relays of this size without magnetic screening would therefore be totally unsuitable for applications where dense packing is required.
Pickering Series 125 relays have a typical interaction figure of 1%.
