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.

These relays pair the transmission reliability of an interface relay with the fail-safe operation of a safety relay. Use them to communicate signals to devices like motors or sensors. They have interlocking contacts—also known as force-guided or mechanically linked contacts—so opposing contacts won't close at the same time. This minimizes the chance of arcing, so electricity won't jump across the contacts and interfere with your relay or system. They also have an interface that isolates input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. Mount them on 35 mm DIN rail (also known as DIN 3 rail). The relays disconnect from the socket for quick replacement.

Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.

Relays with screw terminals or spring-clamp terminals are considered interface relays, so they’re placed between your controller and components to isolate the input and output circuits. This means they protect your component from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission. They are often used for switching applications, such as small motors and pilot lights. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail). Relays with spring-clamp terminals connect and disconnect to wires without needing to turn screws. With no screws to shake loose with vibration, the terminals hold tight over time.
