The Pickering Series 100 is a complete range of Single-in- Line (SIL) reed relays primarily intended for direct drive from 4000B CMOS or similar low current sources. They feature a very low level of thermal EMF. The mercury wetted relays in the range may be driven directly from TTL logic.
They are also useful for applications where conservation of current is important, for example, battery powered equipment.
The extremely low level of thermal EMF, about 1 microvolt or less, of the dry versions make them ideally suited to applications such as data acquisition or thermocouple switching.
An internal mu-metal magnetic screen is fitted to avoid the effects of magnetic interaction between relays.
If you do not require quite such high coil resistances or if a slightly smaller device is desired, please look also at our Series 101 which may be driven directly by 74HC or 74HCT logic.
Other special parts are also available that may be operated from 3 Volt logic, please contact our Sales Office for further information.
