Use these switches 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. Switches must be connected to the required barriers (sold separately), which reduce the current and voltage coming from your power source. Unlike the switches, however, the barriers must be located in a separate nonhazardous area.

Also known as inductive proximity switches, these switches 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. Switches 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.

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

All switches seal out dust. IP66 rated switches protect against high-volume washdowns. Switches rated IP67 can be submerged for up to 30 minutes.

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.

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

A built-in relay produces AC voltage output. These switches are often used with older programmable logic controllers (PLCs). They detect the presence or absence of an object moving at high speeds with a light beam.

Direct sensing switches detect objects when light reflects back from the object. The transmitter and receiver are in the same housing, so they fit in confined spaces.

Receiver switches detect objects when an object breaks the light beam between the transmitter and receiver (both included). They have a longer sensing distance than direct-sensing and reflector switches.

Reflector switches detect an object when it passes between the switch and the reflector, interrupting the beam. They have a longer sensing distance than direct-sensing switches.

IP66 rated switches protect against washdowns.

Set these switches to delay activation by up to five seconds after detecting an object. A built-in relay produces AC voltage output. They’re often used with older programmable logic controllers (PLCs). They detect the presence or absence of an object moving at high speeds with a light beam. All are rated IP66 for protection against washdowns.

Rated NEMA 4X and IP66 for use in washdown environments, these controls have an actuator that’s sealed to keep water out. An infrared sensor uses body heat to sense movement. They turn lights on when they detect motion and off when a room is empty or there’s enough daylight. To work properly, they need an unobstructed view of your space.

Power controllers (sold separately) are required to switch a 120- or 277-volt AC lighting circuit. They have a relay that switches a maximum 20 amp load.

An infrared light beam senses the lightest finger contact to switch a circuit on or off. The included guard prevents accidental activation. An indicator lights up to confirm that switches are actuated. They’re rated NEMA 4X, 13, and IP66 for protection from corrosion, washdowns, and oil/coolant spraying.

Switches with a 5-pole mini plug can quickly be changed out.

The light touch of a finger turns circuits on and off without pressing down a contact. Program these switches to fit your application—control their color, pattern, and sensitivity. Change the color to show different process statuses. For more visibility, change the intensity of the color or choose a light pattern. These switches can flash, rotate, and show other patterns, all at speeds you can control. To change how much force they need to actuate, alter the sensitivity. With a high sensitivity, they’ll actuate even if you’re wearing gloves. With a low sensitivity, they’re more resistant to accidental actuation.

To program your switch, download the free Banner Pro Editor Software. You’ll need a switch programming kit (sold separately) to connect your switch to the software.

Switches with a copolyester base are FDA compliant for incidental food contact once installed.
