Spade-Terminal Relays

Relay-Socket Mount

Relay-Socket/Surface Mount

Relay Socket with Screw Terminals

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 have a slot on the flange for mounting them to flat surfaces. Relay-socket mount relays plug into a socket (sold separately).

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

Circular-Pin Relays

11-Terminal Relay

Relay Socket for 11-Terminal Socket

The circular pin terminals plug into relay sockets for easy installation. Also known as ice cube relays.

Relays rated for horsepower (hp) are built to handle tough, repetitive-use applications.

Relays with a lockable test button allow you to test whether a relay is working without an electrical signal. They’re helpful for testing relays before you install them, or for checking that installed relays are working properly.

Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted to a flat surface.
