Description

The MRE Reed Relay is a special series focused on High Voltage, High Current and High Insulation Resistance. This relay is capable of switching up to 1 kVDC, and, considering its compact size, it provides an extra high breakdown voltage of 7 kVDC (HV version) across the open contacts, or high carry current of 5 Amps (HC version).

This compact Dual-channel Dry-switch design uses two contacts in series or connected in parallel. Also, it features an integrated Magnetic Shield and high creepage distance pinout. As a result, you can expect High Insulation Resistance of 10 TOhm across open contacts as well as between coil and contacts, and thus a very Low Leakage Current in the picoamperes range.

Lastly, from reliable switching to long lifetime and Low Contact Resistance (ON-Resistance), the MRE relay series is ideally suited for ARC testers, precise testers, automated test equipment and medical equipment.

Product Training Module – RF Reed Relays Part I  

Product Training Module – RF Reed Relays Part I

Welcome to Standex Electronics' RF Reed Relays Part I training module. Reed relays have long been known to have the capability to switch and carry RF signals and fast digital pulses. Hardly anyone thought reed relays were capable of switching and carrying RF up to 20 GHz, because the reed switch's leads are composed of nickel/iron which has a relatively high permeability or (MU). However, 20GHz is now a reality at Standex Electronics. We will be presenting the reasons Standex Electronics and their design team have made this possible.

Product Training Module – RF Reed Relays Part II  

Product Training Module – RF Reed Relays Part II

Welcome to Standex Electronics' RF Reed Relays Part II training module. This second RF presentation assumes you have already heard the first Standex Electronics RF Part I presentation. Understanding the simple physical layout of a reed relay makes it easy to design and rest reed relays for RF and fast digital pulse applications. RF is dependent on the physical layout or signal path it takes while going through circuits and the components that make up those circuits. We will show you how the physical layout of the reed relay will have a direct bearing on the RF signal's success going into and out of the reed relay. Coupled with the relay's physical layout, the materials making up the reed relay are also important.
