Eliminate the need to calculate the sensing distance when using different metals—these switches sense all metal at the same distance. Also known as inductive proximity switches, they remotely sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. They’re often used with programmable logic controllers (PLCs). All meet American, Canadian, and European safety standards. They’re also rated IP66, IP68, and IP69K for protection against dust, temporary submersion, and high-pressure, high-temperature washdowns. Also known as K=1 sensors.

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. Projecting switches, also known as non-embeddable or unshielded switches, must be mounted with the area around the sensor face free of metal. They have a longer sensing distance than flush switches.

Stainless steel switches resist corrosion better than brass switches. They’re best for harsh environments.

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

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.

Rotate the face on these switches five different directions for easy installation and positioning—they work with both AC and DC inputs. Unlike traditional limit switches that have actuators, these noncontact switches adjust for front, top, bottom, left, or right facing objects. They have inductive sensors to detect objects even if they’re covered by water, oil, dirt, or a surface finish, making them good for conveyor systems and bin filing operations in refineries, mills, and other challenging environments. Maximum sensing distance is based on the object's material; the distance listed is for mild steel.

They are UL and C-UL listed, as well as CE marked, to meet American, Canadian, and European Union safety standards. Some are also CSA certified.

Flush switches, also called embeddable and shielded switches, are more accurate than projecting switches at close range. They also won’t interfere with each other’s signals when installed close together. The face mounts evenly with any material, including metal.

Projecting switches, also known as non-embeddable and unshielded switches, sense objects farther away than flush switches. To work properly, the area around the face must be metal free.

All have 3-pole micro connectors to easily connect and disconnect. Switches with a plug connect to cables with a socket (sold separately). To view switch wiring diagrams, select a part number and click Product Detail.

IP-rated, they all seal out dust and debris. IP 65-rated switches protect against low-pressure washdowns, such as water from a garden hose. IP 67-rated switches can be temporarily submerged.

Detect objects and liquid or material levels to set off actions in your system—regardless of size, shape, or surface finish. These switches send out high-frequency sound waves that target small areas, so the surface and structure of your object won't affect results like photoelectric sensors, which sense using light. This makes them great for materials with uneven surfaces, such as granules and powder. They also sense objects when obscured by smoke, dust, debris, or water, but they don't work as well where there's wind, since it could disrupt their sound waves. Once an object is detected or a set level is reached, the digital output sends a signal to your controller to turn components in your system on or off. Use their plug to quickly connect and disconnect to cables with a socket (sold separately). UL listed, C-UL listed, and CE marked, all meet American, Canadian, and European safety standards.

Switches with two outputs let you set a minimum level on one output and a maximum on the other—for example, you can keep liquid levels constant by turning on a pump when the level drops too low and turning off the pump when it reaches the maximum.

Switches with IO Link connect to a programmable logic controller (PLC), so you can change settings and receive error messages remotely. You need an IO-Link controller (not included) to connect.

90° elbow switches are compact to fit in tight spaces. They’re best for conveyors.

Rated IP67, all of these switches seal out dust and water if briefly submersed.
