Relays

Compact Spade-Terminal Relays

Smaller than standard spade-terminal relays in height and depth, these relays save space inside your control cabinet.

Thin Spade-Terminal Relays

Thinner than other spade-terminal relays, these fit in tight spaces.

Flange-Mount Spade-Terminal Relays

Mount relays to a flat surface using the slot on the flange.

Spade-Terminal Relays

Attach quick-disconnect terminals or plug relays into relay sockets.

Circular-Pin Relays

The circular pin terminals plug into relay sockets for easy installation.

Premium Circular-Pin Relays

Built to handle tough, repetitive-use applications, these are more durable than standard relays.

Long-Life Circular-Pin Relays

With no moving parts, these solid state relays have an extended service life.

Hazardous Location Circular-Pin Relays

These sealed relays meet UL Class I, Division 2, Groups A, B, C, and D for use in hazardous locations.

PC-Board Pin Relays

Solder these relays to a printed circuit board.

Medium-Current Relays

These relays are rated for motors with 1-3 horsepower or 15-90 amps—use them with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

Long-Life Medium-Current Relays

With no moving parts, these solid state medium-current relays have an extended service life.

DIN-Rail Mount Long-Life High-Current Relays

With no moving parts, these solid state relays have an extended service life. Mount them directly to DIN rail.

Infrequent-Cycle High-Current Relays

For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Also known as definite-purpose contactors.

Alternating Relays

Split run time between two devices—this relay will automatically alternate between them.

Thin Signal Relays with PLC Protection and Socket

Prevent voltage spikes from damaging your programmable logic controller or other sensitive control device. Thinner than other signal relays, these fit in tight spaces.
