Associated Parts

Ultraminiature instrumentation grade single in-line (SIL) UMS Series Reed Relay used in very closely stacked matrices. Measure nearly 50% smaller than the standard MS series reed relay. Contains and internal magnetic shield. UL approval.

UL Certificate of Compliance

General purpose micro single in-line (SIL) MS Series Reed Relay with rugged thermoset overmolded package has a standard internal magnetic shield. This instrumentation grade relay can be stacked in close matrices. Available in high frequency version up to 1GHz. Optional diode. UL approval.

UL Certificate of Compliance

The MF series reed relay is an ultra-high density vertical square shape for high density PCB assembly, which has the smallest surface size of 4.35mm x 4.35mm in our product line. The size allows you to meet the KGD demands of the IC industry by mounting 500 relays on an 8” board and 1000 relays on a 12” board.

We also offer additional options such as single/double shield and relay sockets for easy maintenance. Please contact our sales engineers for more details.

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.
