The Pickering Series 115 is a range of Single-in-Line relays intended for very high density applications such as A.T.E. switching matrices or multiplexers.

They are pin compatible with the Pickering Series 116 and 117 but have a slightly higher profile.

The reed switch/coil assemblies used in this series are the same as used in the long established and well proven, Series 109 and 109P.

Two switch types are available. Both types have sputtered ruthenium contacts for long life and high reliability.

Switch type number 1 is better suited for general purpose applications. It has a layer of copper beneath the ruthenium to help dissipate the heat from the contact area. This gives an improved current inrush handling ability.

Switch type number 2 should be chosen for low level or 'cold' switching applications.

Single switch versions require a board area of only 0.15 inches x 0.27 inches. This is one quarter of the board area of the industry standard 0.2 x 0.8 inches Single-in-Line package. The very small size of these relays often makes it possible to increase the functionality of existing designs without increasing the size of printed circuit boards.

The relays feature an internal mu-metal magnetic screen. Mu-metal has the advantage of a high permeability and low magnetic remanence and eliminates problems that would otherwise occur due to magnetic interaction. Relays of this size without magnetic screening would be totally unsuitable for applications where dense packing is required.

3 volt, 5 volt or 12 volt coils are available. An internal Back E.M.F suppression diode is available as an option.
