Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.
Screw Terminals—Relays with screw 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).
Spring-Clamp Terminals—Relays with 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.
Circular-Pin Terminal and Quick-Disconnect Terminal—Relays with circular-pin terminals or quick-disconnect terminals are hermetically sealed—completely air- and watertight—to shield internal parts from gases, moisture, and other contaminants. They plug into relay sockets (sold separately) for easy installation.
Sockets with Screw Terminals—Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces.
