The Pickering Series 115 is a range of Single-in-Line reed relays designed for high-density applications such as A.T.E. switching matrices and multiplexers. The 115-1-A-12/2 variant features a 12 V coil, Switch Type 2 for low-level or 'cold' switching applications, and sputtered ruthenium contacts with an insulation resistance greater than 10¹² Ω. It operates within a temperature range of -20 to +85 °C, with an optional internal diode. The relay requires a board area of 0.15 inches × 0.27 inches and includes an internal mu-metal magnetic screen to enable dense side-by-side packing. Maximum switching power is 10 W at 12 V with a contact current rating of 0.5 A. The part is pin-compatible with Series 116 and 117.
The Pickering Series 115 is a range of Single-in-Line relays intended for very high density ap pli ca tions 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.
The relays 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 packge. The very small size of these relays often makes it possible to in crease 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 un suit able for ap pli ca tions 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.
