Detect unwanted slowdowns in a rotary shaft that could cause machine damage and downtime. These switches are often used on drivetrains, conveyors, and other power-driven components. They come with a pulser disc, which you’ll need to attach to the shaft by drilling and tapping a hole. Once mounted, the disc rotates with the shaft and creates magnetic signals that the switch senses. When the speed falls below a set point, the switch will trigger an alarm or turn off the system.

Switches are UL listed and rated NEC Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. They have an explosion-proof housing and are also rated NEMA 4X for washdown and corrosion protection.

Use these sensors to sense objects in volatile areas. Intrinsically safe, they produce a NAMUR signal, which operates at a low current and voltage, so they won’t ignite or create sparks in hazardous locations. They are ATEX and IECEx internationally certified to protect against explosion in environments containing flammable gases and combustible dust. Sensors must be connected to the required barriers (sold separately), which reduce the current and voltage coming from your power source. Unlike the sensors, however, the barriers must be located in a separate nonhazardous area.

Also known as inductive proximity sensors, these sensors detect metallic objects—even if they’re obscured by water, oil, dirt, or a surface finish. Send their signal to programmable logic controllers (PLCs) to support automated processes. Sensors meet various domestic and international safety standards.

Support flow and temperature control in your system with these intrinsically safe sensors, 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 sensor 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. 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 sensors have a 4-pole M12 plug to connect to NAMUR cables (sold separately), letting you quickly connect and disconnect the sensor from your equipment. Connect them to programmable logic controllers (PLCs) to support automated processes. Sensors 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 sensors 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.

Because you can rotate the sensor, these make good replacements for limit switches with actuators that could break when hit. They’re often known as inductive proximity sensors 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 sensors to programmable logic controllers (PLCs) to support automated processes.

These sensors have a 4-pole 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.

IP rated, all sensors seal out dust and water from high-pressure washdowns.

Commonly used to measure the speed of motors and other rotating equipment in the oil and gas industry, chemical plants, and grain mills, these sensors detect objects each time they pass through the slot. Sensors 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 sensors must be connected to the required barriers (sold separately), which reduce the current and voltage coming from your power source.

Also known as inductive proximity sensors, 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. Sensors meet various national and international safety standards, and they’re rated IP67 to protect against dust, washdowns, and temporary submersion.

Often used in the stamping process to count small metallic parts, such as screws, nuts, and washers, these sensors 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. Sensors meet ATEX international certification to protect against explosion in environments containing flammable gases. Prior to use, sensors must be connected to the required barriers (sold separately), which reduce the current and voltage going into the hazardous location.

Also known as inductive proximity sensors, they sense objects even if 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. Sensors meet various national and international safety standards, and they’re rated IP67 to protect against dust, washdowns, and temporary submersion.

Mount these intrinsically safe sensors 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. Sensors must connect to the required barriers (sold separately), which reduce the current and voltage going into the hazardous location.

Also known as inductive proximity sensors, they remotely sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. These sensors have the same high sensing 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 sensors are rated IP67, so they stand up to dust and brief submersion. They meet various domestic and international safety standards.
