Rugged enough for mining operations, these limit switches require a high actuation force, like heavy rocks moving on a conveyor. They open and close a circuit as quickly as a snap-acting switch but have a larger actuator for larger objects. The roller on the end of the lever arm reduces friction to prevent wear and tear on the switch. Rated NEMA 4 and 13 as well as IP67, these switches are protected from dirt, oil spraying, and temporary submersion.

To determine if you need a right or left actuation direction, stand facing where you'll put the switch. If objects will be passing to the right, you'll need a right actuation direction. If they'll be passing to the left, you'll need a left actuation direction.

Prevent equipment from automatically restarting—these switches must be manually reset each time they're actuated. Pull the knob to reset. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. 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.

Rated IP67, these switches seal out water if they’re washed down or briefly submersed.

Styles B and C have a roller lever actuator that allows parts to glide across the actuation surface with minimal friction. Style C have an actuator that allows you to adjust its height, making it easier to align the switch with the target during installation.

Trigger actions in devices as small as phones and drones. The smallest snap-acting switches we offer, these switches fit into the tiniest of spaces and help keep weight to a minimum. Because snap-acting switches open and close circuits faster than other switches—reducing the time that contacts are near one another—they prevent contacts from sticking. They also minimize the chance of arcing, so electricity won’t jump across contacts.

Plunger actuator switches send a signal when the actuator is pushed directly downward. They have a small footprint, reducing the risk of accidental switching.

Also known as inductive proximity switches, these detect metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. Sensing distance is based on the target material. The distance listed is for mild steel. They’re often used with programmable logic controllers (PLCs) and produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).

Flush switches, also known as embeddable or shielded switches, can be mounted so that the sensor face is level with the surface of any material, including metal. They’re more accurate than projecting switches at close range and can be mounted close together without causing interference.

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

IP67 and IP68 rated switches are protected from temporary submersion.

These inductive proximity switches sense metallic objects each time they pass through the slot, even when they’re obscured by water, oil, dirt, or a surface finish. Use them to measure the speed of rotating equipment and to count or detect moving objects, such as sheet metal being fed into a stamping process. Send their signal to programmable logic controllers (PLCs) to support automated processes within your system. Switches are UL and C-UL listed, CE marked, and CSA certified, meeting strict domestic and international safety requirements. They’re also rated IP67 to protect against dust, washdowns, and temporary submersion.

Turn the face on these switches to sense metallic objects from the front, sides, top, or bottom. They’re a good replacement for limit switches with actuators that often break when hit. Also known as inductive proximity switches, they detect objects even if they’re covered by water, oil, dirt, or a surface finish. They’re often used in conveyor and bin filling systems, refineries, and mills. Sensing distance is based on the type of material being sensed; the distance listed is for mild steel. LED status indicators on the corners mean you can check your switch from any angle. All switches meet American, Canadian, and European safety standards.

You can send PNP or NPN signals from these switches to programmable logic controllers (PLCs). Use Testers for Proximity and Photoelectric Switches to determine the signal output of a switch you’re replacing.

Flush switches, also known as embeddable and shielded switches, are more accurate than projecting switches at close range. They also won’t cause interference when mounted close together. The sensor face mounts evenly with any material, including metal.

Projecting switches, also called non-embeddable and unshielded switches, sense objects farther away than flush switches. But, they require the area around the sensor to be free of metal.

Switches with a 4-pole micro M12 plug connect to cables with a socket (sold separately), so you can quickly connect and disconnect them. To view switch wiring diagrams, select a part number and click Product Detail. Attach switches with screw terminals to optional M12 connectors with a receptacle to convert them to a standard 4-pole M12 plug.

All switches seal out dust and stand up to some submersion. IP69- and IP69K-rated switches also handle high-pressure washdowns.

Actuate your switch with precision—these proximity switches have an easy-to-read screen for precise distance inputs, measurements, and troubleshooting. Often installed on assembly lines with machine arms, these switches pair with a sensor (sold separately) to determine if parts are in their expected location. When items are located outside your specified range, these switches send a signal to automatically stop your equipment or to notify you of the error. Also known as inductive proximity switches, they sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. Choose your switch based on the signal output required for your system. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).

Sensors can be mounted so the face is flush with the surface of any material, including metal. They’re also known as embeddable or shielded sensors. IP60 rated sensors protect against dust. IP67 rated sensors protect against temporary submersion.

Use a mounting bracket to mount these switches to any surface. Use an end plate to hold the switch in place when mounting to a DIN rail.

Mount these flat switches to a base or rail. Also known as capacitive proximity switches, they remotely sense both metallic and nonmetallic objects but their strength is in sensing materials such as plastic, ceramic, and clear targets. Often used with programmable logic controllers (PLCs), they produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included). All are projecting switches, and must be mounted with the area around the sensor face free of metal. They’re rated IP68 for protection from washdowns and temporary submersion.
