4mm Relays Overview

Series 120 50 124 Reed Relays

ULTRA-HIGH DENSITY 4MM REED RELAYS

 

Ultra-high density 4mm2 TM reed relay product lines are up to 1 Amp switching, whilst still stacking on a 4mm x 4mm pitch, allowing the highest packing density currently available in the industry.

The relays feature the highest quality instrumentation grade reed switches and internal mu-metal magnetic screens to minimise magnetic interaction when relays are stacked closely together.

4mm2 TM  reed relays are ideal for very high density applications such as A.T.E. switching matrices or multiplexers.

  • 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.
