Commonly used to measure the speed of motors and other rotating equipment in the oil and gas industry, chemical plants, and grain mills, these switches detect objects each time they pass through the slot. Switches are intrinsically safe and produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks while being used. ATEX and IECEx certified, they meet international standards to protect against explosion in environments containing flammable gases and combustible dust. Prior to use, these switches must be connected to the required barriers (sold separately), which reduce the current and voltage coming from your power source. Unlike the switches, barriers must be installed in a separate nonhazardous area.

Also known as inductive proximity switches, they sense metallic objects even when they’re obscured by water, oil, dirt, or a surface finish. Send their signal to programmable logic controllers (PLCs) to support automated processes within your system. Switches meet various national and international safety standards, and they’re rated IP67 to protect against dust, washdowns, and temporary submersion.

Twist the sensor to detect metallic objects where explosive dust or gas may be present—the sensor rotates for front, side, top, or bottom sensing. These switches are UL and C-UL listed as well as ATEX and IECEx certified for hazardous locations. Their NAMUR signal produces low current and low voltage, so they won’t spark or ignite. You must connect them to a barrier (sold separately), which reduces the current and voltage that enters your hazardous area. Install the barrier in a separate location that doesn’t contain explosive gas or dust.

Because you can rotate their sensor, these switches make good replacements for limit switches with actuators that could break when hit. They’re often known as inductive proximity switches and detect objects even if they’re covered by water, oil, dirt, or a surface finish. Sensing distance is based on the type of material that’s sensed; the distance listed is for mild steel. Send signals from these switches to programmable logic controllers (PLCs) to support automated processes.

These switches have a 4-pole micro M12 plug that connects to cables with a socket (sold separately), so you can quickly connect and disconnect them. You can also check on them from any angle, thanks to LED status indicators on their corners. All are CE marked for safety.

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. Their sensor 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. But, the area around the sensor must be metal free.

IP rated, all switches seal out dust and water from high-pressure washdowns. IP67- and IP68-rated switches also withstand some submersion.

Mount these intrinsically safe switches to flat surfaces in volatile areas. Their low-current, low-voltage NAMUR signal means they won’t ignite or create sparks while in use. ATEX and IECEx certified, they meet international standards to protect against explosion where combustible dust and flammable gases are present. Switches must connect to the required barriers (sold separately), which reduce the current and voltage going into the hazardous location. While the switches can safely be used in hazardous areas, the barriers must be installed in a separate nonhazardous area.

Also known as inductive proximity switches, they remotely sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. These switches have the same high switching distance for all metals. Because of this, they’re often used for detecting weaker metals, such as tin and aluminum, in the food and beverage industry. The larger the size, the greater the sensing distance. Send their signal to programmable logic controllers (PLCs) to support automated processes within your system. All of these switches are rated IP67, so they stand up to dust and brief submersion. They meet various domestic and international safety standards.

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 of the same size. They also have a 4-pole Micro M12 plug that connects to cables with a socket (sold separately), letting you quickly connect and disconnect the switch from your equipment.

Often used in the stamping process to count small metallic parts, such as screws, nuts, and washers, these switches detect objects as they pass through the ring via tubing or a funnel. Intrinsically safe, they produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks while in use. Switches meet ATEX international certification to protect against explosion in environments containing flammable gases. Prior to use, switches must be connected to the required barriers (sold separately), which reduce the current and voltage going into the hazardous location. While the switches can safely be used in hazardous areas, the barriers must be installed in a separate nonhazardous area.

Sense objects in hazardous locations with these intrinsically safe switches. Unlike standard proximity switches, they use a NAMUR signal to operate at a low current and voltage, so they won’t ignite or produce sparks when used. Switches meet ATEX international certification to protect against explosion in environments containing flammable gases and combustible dust. These switches must be connected to the required barriers (sold separately), which reduce the current and voltage flowing into the hazardous location from your power source. While the switches can safely be used in hazardous areas, the barriers must be installed in a separate nonhazardous area.

Also known as capacitive proximity switches, they sense both metallic and nonmetallic objects, but their strength is in detecting plastics, liquids, powder, granular materials, and clear targets. The larger the size of the sensor, the greater your sensing distance is. They're often used with HVAC systems and programmable logic controllers (PLCs). Switches meet various domestic and international safety standards.

Mount flush switches so that the sensor face is level with the surface of your material. Also known as embeddable or shielded switches, they’re more accurate than projecting switches at close range and can be mounted close together on any surface 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.

All switches are protected from dust and washdowns. IP67 switches protect against brief submersion. IP68 switches protect against prolonged submersion.

Support flow and temperature control in your system with these intrinsically safe switches, which sense when a valve is open or closed in volatile areas. Often used in chemical plants and oil and gas facilities, they are ATEX and IECEx internationally certified to protect against explosion where flammable gases and combustible dust are present.

Mount the switch to your valve actuator, and affix a corresponding activator (sold separately) onto your actuator’s shaft. As the valve opens and closes, the activator rotates until its targets align with the two inductive sensors on the switch. Once they’re aligned, your system will know that the valve is either open or closed—providing reliable feedback on your valve’s position. These switches have a 4-pole micro M12 plug to connect to NAMUR cables (sold separately), letting you quickly connect and disconnect the switch from your equipment. Connect them to programmable logic controllers (PLCs) to support automated processes. Switches meet various national and international safety standards, and they’re rated IP67 to protect against dust, washdowns, and temporary submersion.

Mounted to your circuit board, these switches trigger when magnetic components get near, and reset as they move away. They’re often used to turn on electronics, such as starting up a laptop when you open it. To install, push the contacts through holes in a circuit board, then solder them in place.

Switches with a plastic housing withstand impact better than switches with a glass housing. The plastic also forms an airtight seal to block out contaminants. Use them in dusty or dirty environments where an optical switch might fail.
