Omron’s relays are divided in three groups.  The first group is DC power relays. DC power relays are relays developed specifically for switching high DC (Direct Current) loads from 25 A to 200 A.  The second group is PCB power relays. PCB power relays are designed to handle higher loads featuring a switching capacity of 3A, all the way up to 30 A. These relays are used in many different applications, which might require special features such as DC or AC coils, sensitive coils, latching coils, high inrush handling capabilities, conformity to flammability tests, low operation noise, big contact gap, and high dielectric strength just to name a few. The final group is low signal relays. Low signal relays are available in electromechanical signal relays, high frequency relays and MOSFET relays. Signal relays are miniature relays designed for low level current switching, generally up to 2 A. Its contacts are designed for excellent reliability and are made of special materials that provide stable contact resistance, available in 1 contact form A, 1 contact form C and 2 contacts form C. Its coils are generally of very low power consumption and are offered in latching and non-latching versions. The High Frequency versions are designed for applications where signals of several hundred MHz up to several GHz have to be switched. A MOSFET Relay is a solid state alternative to low signal relays. It has an input LED, a photodiode array (used as a photocoupler) and a MOSFET chip used in the load switching circuit.  This PTM will focus on Electromechanical Low Signal Relays.
