Omron STI Force Guided Relays and Mirror Contact Relays

Force-guided (or positively-guided) relays have contacts featuring a mechanical interlocking system. The interlock is designed such that two contacts on the relays will not contradict each other, even if one of the contacts fails. All of Omron STI's force-guided relays conform to IEC60947-1-1 so they are available to use in your safety control circuits. They also come in a variety of current ratings and configurations.
The mirror contact relays conform to EN 60947-4-1 by using a combination of the relay block and the auxiliary contact block.
