Fit these relays where standard spade-terminal relays are too big.

Often used for high-speed switching at low-current levels, these solid state relays have no moving parts, so they switch faster, last longer, and are quieter than mechanical switches.

Isolate input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal.

With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission.

Smaller than relays with electrical wiring, these relays fit in compact devices. Mount them through holes on circuit boards with their solder pin terminals.

With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.

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.

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.

An extended housing shields the terminals on these relays from weather.

With no moving parts, these solid state relays require less maintenance and last longer, switch faster, and are quieter, than mechanical relays. Also known as automotive relays.

Reduce connection errors on circuit boards that control machine guards and other safety devices. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes.

Receive signals from safety monitoring relays or controllers to switch devices off and on because of a system failure.

Control and diagnose issues with safety-critical circuits.

Often used to regulate the speed of AC fans or keep a heater at a set temperature, these relays connect directly to sensors to calculate and adjust output power. This allows you to use an analog input without converting it to a digital signal to control output power.

Also known as an air-to-electric switch, this relay converts an air signal to an electric signal.

Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage.

Monitor phase, voltage, and frequency at the same time to protect motors, generators, and other three-phase circuits from burning out or overheating.

Operate equipment that cycles on and off from your control cabinet.

Switch lighting systems on and off—these relays can handle the high switching current on large overhead light systems.

An enclosure covers the terminals on these relays to help prevent damage from dust or accidental bumps.

Detect and mitigate ground faults to prevent harm to equipment, circuits, and people.
