Spade-Terminal Relays

Using a low-current signal, these relays are often used to control small motors and heaters. These relays attach to quick-disconnect terminals.

Surface mount relays, also known as power relays, have a slot on the flange for mounting them to flat surfaces.

Relay-socket mount relays, also known as ice cube relays, offer three ways to connect. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals.

Relay-socket/surface mount relays can plug into a socket or mount to a flat surface.

Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They can also mount to a flat surface.

Screw Terminal Relays

Use the screw terminals to hardwire these relays. The built-in enclosure protects contacts from dust and dirt. These relays accept voltage drops up to 50% of the rated voltage without switching. They’re often used with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

An enclosure covers the terminals on these relays to help prevent damage from dust or accidental bumps. They have an LED indicator, so you can quickly see what switching position your relay is in. Hardwire them to your equipment with the included wire leads. Rated NEMA 1, these relays are intended for indoor use only.
