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.

Download the Series 100 Datasheet

All our data sheets have been recently updated to include additional environmental specifications, mechanical characteristics and relay weights, RF plots for coaxial relays (showing VSWR, isolation and insertion loss), interactive links to further useful information, comparison tables to similar relay ranges and much more.

  • Free Sample Service - determining which components to design in can be challenging. Fortunately, here at Pickering Electronics, we provide free working samples to help you evaluate our high-quality Reed Relays.
  • Reed Relay Selector Tool - this tool will help you narrow down our large offering to get you the correct reed relay for your application. Once you narrow your selections down you can download a relay datasheet for more information, purchase in stock items or request a quote to find out lead times of made to order (MTO) relays.
  • Concise Tech Guide - this guide will help you to maximise the reliability of your design.
  • Quality Assurance - learn more about the various accreditations and certifications that Pickering holds.
  • Custom Designed Reed Relays - With over a thousand catalog parts there is plenty of choice when choosing the right Reed Relay for your product, but if you cannot find one suitable for your needs Pickering can customize our standard reed relay parts to suit your specific requirements and applications.
All Pickering reed relays feature the highest quality instrumentation grade reed switches making them suitable for the most demanding applications. Internal mu-metal magnetic screens (optional on Series 103) allow very high packing density. Diodes are optional.

The below table will help you narrow down our offering to get you the correct reed relay for your application.
