Smaller than relays with electrical wiring, these relays fit in compact devices. Mount them through holes on circuit boards with their solder pin terminals. Use them to control heaters, fans, and other high-power components from a low-power circuit.
Solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter than mechanical relays.

Circuit Board Safety Relays
8 Terminals
10 Terminals
14 Terminals
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.
Relays with a mechanical indicator show you whether they’re switched on or off with a flag. Peek through the window on the side to quickly check the flag’s position.
Relays with surge suppression coverage protect sensitive electronics from damage and malfunction by eliminating voltage spikes. Switching off a relay can generate surges of 300 to 500 volts, but a diode within these relays suppresses these surges. An LED indicator on these relays lights up when they’re on, so you know at a glance if they’re wired correctly.
