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 have a slot on the flange for mounting them to flat surfaces.

DIN-Rail Mount Solid State Relays
Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.
Relays with an integrated heat sink disperse heat to increase the relay’s current rating.
Relays with an integrated fan are best for applications that generate more heat. The fan automatically turns on to provide additional cooling. When the temperature exceeds 176° F, an alarm sends a signal to an external device, such as a controller or indicating light.

Solid State Screw Terminal Relays
With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.
IP20 rated relays prevent fingers and other objects from touching live circuits.
Heat sinks disperse heat to increase the relay’s current rating. Mount them to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces. Before mounting one-circuit relays, silicone compound should be applied between the heat sink and relay. Silicone is sold separately for 75A and 90A one-circuit relays. Two-circuit relays don’t require silicone for mounting.

Infrequent-Cycle Relays
For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Connections are accessible from the front, so you can mount relays side-by-side. Also known as definite-purpose contactors.
Also Available: Auxiliary contacts for 3.8"-7.2" Ht. relays. They allow you to add a signaling device or control another relay. Please select 6564K99, then select the McMaster-Carr part number of your relay and whether you want to switch one circuit on (1 Normally Open) or off (1 Normally Closed).

Sequenced Latching Relays
These relays switch through a series of different circuit configurations every time they receive an input voltage. The input voltage latches them in position, so they don’t require a constant voltage to stay switched. Use them to control motors, pumps, and lighting. The covered terminals prevent contact with live connections. Mount to 35 mm DIN rail. Also known as step relays.
