Install these limit switches where changing a battery or routing wires might be difficult—they power themselves when a moving object contacts the actuator. Place them up to 330 ft. away from the receiver (sold separately). These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator.

Rod actuators open or close circuits when material pushes against the rod. The rod extends from the body of the actuator, so these switches are ideal when objects actuating the switch are further away.

Use an antenna (sold separately) to increase the maximum transmission range to 984 ft. They also strengthen the signal if there are obstacles between your switch and receiver.

Shorter and thinner than other safety limit switches, these are sized to fit tight spaces. They protect machinery and ensure the safety of personnel. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. They send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects. All are NEMA and IP rated for protection from washdowns.

Switches with a rod actuator have a large actuation area with a rod extending out of the actuator’s body. They’re best where the object actuating the switch is far away.

Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. The actuator won’t snap if pushed backward, such as if there’s a jam in your system.

Styles E and F have an actuator that allows you to adjust its height, making it easier to align the switch with the target during installation.

NEMA 13 and IP67 rated switches are protected from oil/coolant spraying and temporary submersion.

Protect machinery and ensure the safety of personnel—these switches have positive-force contacts that will open the circuit when actuated even if a spring fails or the contacts stick. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.

Switches with a rod actuator use a rod extending out of the body to actuate, so they’ll activate even if an object is far away.

Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. Since the actuator is flexible, it won’t snap if pushed backward. That makes these switches a great choice for systems that get jammed often.

Styles D, E, and F have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.

Switches with a steel actuator are more durable than switches with a plastic actuator. They also handle higher loads.

Switches with a plastic actuator limit wear and tear on passing objects better than switches with a steel actuator.

Rated NEMA 3S and IP69K, these switches can handle washdowns with high pressures and temperatures. They’re also protected from oil/coolant spraying, precipitation, and temporary submersion. When an object in motion contacts the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.

Styles D, E, and F let you adjust the actuator’s height to align it with your target.

Safely open or close a circuit near ignitable gases and dust—the housing on these switches seals in anything that could ignite flammable material. You'll know they're safe because they're NEC Class I, Division 1, Groups B, C, and D; and Class II, Division 1, Groups E, F, and G certified for hazardous locations. These switches send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects.

Stack these slim switches together, or fit them into tight spaces. They're rated IP67 for protection from temporary submersion. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. They’re often used on conveyor systems and elevators.

Wobble stick actuators open or close circuits when an object hits the flexible arm. The arm has a 360° range of motion, so it can be actuated from any direction. This means that if there’s a jam, these switches are less likely to break than switches that are aligned to a specific direction.

Switches with a 4-pole micro M12 plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

Rated NEMA 4 and IP66, these enclosed switches have a sealed actuator for protection from washdowns. They open and close circuits quickly to minimize arcing and prevent contacts from sticking.

Open and close circuits in a snap. These switches actuate quickly to minimize arcing and prevent contacts from sticking. They’re often used to indicate that an appliance or enclosure door is open. You can also use them inside limit, pressure, and temperature switches.

Switches with a wobble stick actuator have a flexible arm that can actuate from any direction.

A simple automation solution that requires no programming, these valves are activated when an object, such as a box rolling on a conveyor, pushes the actuator. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they go back to their starting position as soon as the actuator is released. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

Normally closed valves block airflow until actuated.

Valves with a two-direction actuator are activated by objects from both sides.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.
