SIL / SIP 5 Watt Switching Reed Relays

All Pickering reed relays feature the highest quality instrumentation grade reed switches making them suitable for the most demanding test applications. Internal mu-metal magnetic screens (optional on Series 103) allow very high packing density without magnetic interation. Diodes are optional in most reed relays.

Pickering Series 117 Reed Relays

Single-in-Line (SIP) Reed Relays
5 Watts switching - Very high packing density. 1 Form A (SPST) stacks on 0.15 x 0.27 inches pitch. 2 Form A (DPST) stacks on 0.15 x 0.40 inches pitch

• The relays take up the minimum of board area, conserving PCB space
• Many benefits compared to industry standard relays. Learn more here >.

• Plastic package reed relay with internal mu-metal magnetic screen

The Pickering Series 117 is a range of Single-in-Line (SIP) reed relays intended for very high density applications such as Automatic Test Equipment (A.T.E.) switching matrices or multiplexers.

They are available with either 1 or 2 Form A (energize to make) reed switches. These reed relays are the ideal choice for very high density test 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 Series 117 switch rating of 5 Watts, 0.5 A is adequate for most instrumentation applications. If a higher rating is required, the Series 116, which is rated at 10 Watts, 0.5 A should be considered. The relay footprint and pin configurations of the Series 116 are identical but the case height increases slightly to 0.49 inches (12.5 mm).

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 and 5 volt coils are available with an optional Back E.M.F suppression diode.
