Pickering Electronics Series 110 110-1-A-5/1

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. 3, 5 and 12 Volt coils are standard, with the option of an internal diode. 5 Volt coils have a resistance of 500 ohms and may be driven directly from TTL logic.
