Lighting Contactors | McMaster-Carr

Quickly and safely mount these relays on 35 mm DIN rail (also known as DIN 3). IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits.

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.

Infrequent-Cycle 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.

Touch-Safe DIN-Rail Mount Infrequent-Cycle Relays

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

High-Current Lighting Relays

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

Water-Resistant Stud-Terminal Relays

Sealed to keep out water, these relays are often used for DC-powered equipment such as forklifts, floor scrubbers, and trucks.

Stud-Terminal Relays

Suitable for DC-powered equipment such as forklifts, floor scrubbers, and trucks.

Analog-Input Proportional-Control Relays

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.
