The Series 101 CMOS Drive relays have very high coil resistances. 5 Volt dry versions may be driven directly from 74HC or 74HCT logic without the need for additional drivers.

74HC logic will drive up to 4mA at 5 Volts, therefore a coil resistance of 1600 ohms is desirable to avoid running the IC at its maximum rating; 1600 ohms is the coil resistance of the single pole dry Series
101. They may be stacked on 0.3 inches pitch (7.6mm) and as they have an internal mu-metal magnetic screen, there is no risk of magnetic interaction problems.

Both dry and mercury wetted switches are available in a range of configurations and coil voltages. The switches in the 2 Form A version are vertically stacked so the relay requires the same board area as the 1 Form A type.

A special 1 Form A, 5 Volt version is available with an even higher coil resistance of 3000 ohms. This is particularly suited to applications such as battery powered portable equipment as it requires a coil current of only 1.7 mA. This part, the 101-1-A-5/17 or 17D has the advantage of a lower level of thermal EMF of 3 microvolts or less.

Other special parts are also available that may be operated from 3 Volt logic.

  • 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.
