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.

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