DIN-Rail Mount Solid State Relays
Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. An LED indicator lights up when these relays are connected, so you can quickly confirm that they’re wired correctly. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.
Relays with an integrated heat sink disperse heat to increase the relay’s current rating.

Circuit Board Safety Relays
Reduce connection errors on circuit boards that control machine guards and other safety devices. Also known as force-guided contact relays, they have contact pairs that won’t close at the same time, even if contacts stick or weld shut. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes. Use them to control high-power components, such as fans and heaters, from a low-power circuit.
