The Pickering Series 116 is a range of Single-in-Line (SIP) reed relays intended for very high density applications such as A.T.E. switching matrices or multiplexers.
They have a switch rating of 10 Watts, 0.5 Amps and are pin compatible with the Pickering Series 117 reed relays which have a power rating of 10 Watts and a lower profile height of 0.38 inches (9.65 mm).
Switches have sputtered ruthenium contacts making them ideal for low level or “cold” switching applications.
1 or 2 pole, Form A (energize to make) versions are available.
The single pole version uses the same switch and coil assembly as the Pickering Series 112.
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
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. Interaction is usually measured as a percentage increase in the voltage required to operate a
relay when additional relays, stacked each side, are themselves operated. An unscreened device mounted on this pitch would have an interaction figure of around 40 percent. Relays of this size without magnetic screening would therefore 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.
