Turn the face on these sensors 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 sensors, 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 sensor from any angle. All sensors meet American, Canadian, and European safety standards.

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

All sensors seal out dust and stand up to some submersion.

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

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

Plug In—Sensors with a 4-pole M12 plug connect to cables with a socket (sold separately), so you can quickly connect and disconnect them.

Receptacles—Attach sensors with screw terminals to M12 connectors with a receptacle to convert them to a standard 4-pole M12 plug.

Shut off machinery on your roughest, dirtiest job sites the second someone or something gets too close. Shielded by a polycarbonate housing, these safety light curtains withstand impact better than standard models. Rated IP69, they’re sealed to keep out dust and high-pressure, high-temperature washdowns, so they'll stand up to mud, water, and heat on site. They're often used in construction zones and mining operations. When conditions are too harsh for inspections, use Bluetooth to send diagnostics to your phone. Simply connect to the app to monitor switching status, beam alignment, and other data from afar.

These curtains trigger when the light beams between the transmitter and receiver are interrupted. To selectively allow material to pass through the sensing field, you can program the system to allow one or more beams to be broken without shutting off your machine. To create a perimeter guard that bends around corners, add mirrors to reflect light beams at an angle.

For a complete switching system, combine a transmitter and receiver, which are sold together, with a safety relay (sold separately).

For the Manufacturer User Manual, click on a part number and select Product Detail.

Note: These curtains cannot be used with a full-revolution clutch press or machine. Use only with machinery that can consistently and immediately stop anywhere in its cycle.

Safety Relays

Safety relays send a signal to shut off your machinery when the light beams are breached and restart when the issue is resolved. IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits. Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation. These relays meet ISO and IEC standards for machine safety and can help achieve PL, SIL, or CAT system ratings.
