This high voltage reed relay is capable of switching up to 1kVDC, breakdown voltage of 4.5kVDC, isolation voltage to 7kVDC and features a high insulation resistance (IR) >10^13 Ω. This KT series is supplied in a rugged thermoset overmolded package. Tested in accordance with AEC-Q200, UL listed.

UL Certificate of Compliance

The SHV reed relay is a single in-line and high voltage relay or instrumentation grade reed relay supplied in a molded housing, capable of switching up to 1kVDC and breakdown voltage of 4kVDC. This high voltage reed relay series features an insulation resistance >5 x 10^11 Ω and utilizes minimum PCB area, at only 50% compared to our DIP and DIL reed relay series. It is even smaller than the former potted SIL-HV Reed Relay.

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

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.
