Washdown Enclosed Relays
A NEMA 4X enclosure protects these relays from washdowns, dirt, and corrosion. It also keeps terminals from being bumped accidentally, so you can mount these relays near working areas. Hardwire to your equipment with the wire leads.

Enclosed Relays
An enclosure covers the terminals on these relays to help prevent damage from dust or accidental bumps. They have an LED indicator, so you can quickly see what switching position your relay is in. Hardwire them to your equipment with the included wire leads. Rated NEMA 1, these relays are intended for indoor use only.

Solid State Surface-Mount Timer Relays
Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.
Delayed start (delay-on-make) relays allow you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping a lubricant immediately, but it does not start rotating until the set time has elapsed.
Delayed switch-off (delay-on-break) relays activate with a switch instead of input voltage. When the switch is turned off, the relay remains on for a programmed amount of time before turning off. For example, a projector’s light is turned off with a switch, but its cooling fan continues to run for a set time.
Interval relays use input voltage to turn on for a programmed amount of time. For example, when a part moving down a conveyor reaches a certain location, a cleaning spray comes on for a set time.
Repeat cycle relays turn on for a duration, then off for the same duration. They alternate between the two cycles until input voltage is removed. A common example would be a flashing light.
Switch-on (single-shot) relays require a switch to activate the relay. They’ll stay on for a programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.
Switches with a potentiometer (variable switch) allow you to adjust the delay within the range.
