Make your circuit jump in and out of action at the flick of a switch with a solid state relay. Solid state relays are a newer type of electronic relay which differ from older electromechanical relays in that they contain no moving parts. The moving parts used to open and close circuit contacts in electromechanical relays are prone to wear and tear, meaning that they'll need to be replaced more quickly. As solid state relays don't have these parts, they are more reliable and last longer. They're also not prone to arcing and contact bounce, meaning that they're more precise. Sensata / Crydom solid state relays are the favourite of electrical engineers and robotics technicians alike, as their slick switches control machinery with fast and reliable switching.
Solid state relays are incredibly versatile, as such they can be found in all manner of electrical installations. Some examples include:
To find the best solid state relay, you'll need to consider the application in which you'll use it. There are relays with different contact configurations, control voltages, load currents, and switching types, each suited to the many different potential uses of solid state relays. We've listed some considerations below, but for more information, check out our detailed guide to solid state relays.
