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.

Thin Long-Life Spade-Terminal Relays

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

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.

High-Starting-Current Vehicle Relays

Also known as automotive relays, these relays can handle high starting (inrush) currents.

Weatherproof High-Starting-Current Vehicle Relays

The extended housing covers and protects terminals.

Long-Life High-Starting-Current Vehicle Relays

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

Latching Relays

A single, momentary input voltage switches these relays and locks them in position, so they don't require a constant input voltage to stay on or off.

Alternating Relays

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

Low-Current Timer Relays

Socket-Mount Multifunction Timer Relays

Plug these multifunction timer relays into relay sockets for fast installation and replacement.

Compact Socket-Mount Multifunction Timer Relays

Smaller than standard multifunction timer relays, these relays save space in your control cabinet.

Versa-Mount Multifunction Timer Relays

Install relays in a panel cutout or plug into a relay socket.

Socket-Mount Timer Relays

Plug these timer relays into relay sockets for fast installation and replacement.

Wide-Range Socket-Mount Timer Relays

Postpone starts longer and set wider intervals than with most timer relays.

Versa-Mount Timer Relays

Install these relays in a panel cutout or plug into a relay socket.

Socket-Mount Motor Voltage Monitors

Plug monitors into relay sockets for fast installation and replacement.
