Standex Electronics Logo


Standex Electronics is the leading global reed relay expert. We are the world's largest reed switch manufacturer. Our high quality reed switches are the core switching element in the Reed Relay. Reed technology has unique switching abilities that make our reed relays unique. Most noteworthy are low and stable contact resistance <150 milli-ohms, low capacitance, and high insulation resistance >10^14 ohms. Likewise long life for billions of operations and small size. Furthermore reed relays switch low level signals as a result of their hermetically sealed contacts. Signals as low as fempto amps and nanovolts! Finally Standex Electronics' relays meet many unique applications requirements. See our relays at work in various Test & Measurement applications. Applications such as printed circuit board (PCB) testers and multimeters to data acquisition scanning systems and more.
