The Pickering Series 110 V-SIL (vertical single-in-line) is a
range of magnetically screened single-in-line reed relays that
stack on 0.15 inches by 0.4 inches pitch. The switches in this
range are mounted vertically within the package, this allows
the use of the same switch types as would normally be found
in relays requiring a very much larger board area. In this way,
a 10 Watt switch power rating is achieved. Two types of Form
A (energize to make) switches are available, a general purpose
version and a type suitable for low level or “cold” switching
applications.
These relays require around one third the board area of
the more usual 0.2 x 0.8 inch devices. These are your idea
choice for high density applications such as A.T.E. switching
matrices or where very little board area is available. If a lower
profile device is required, look at the Series 111, which has an
identical pin-out but a height of only 0.26 inches.
The Series 110 is encapsulated in a plastic package using a
very high resistivity resin. The relay has an internal mumetal
screen which totally eliminates the risk of magnetic interaction
problems. 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.
Pickering Series 110 have a typical interaction figure of 5
percent.
