Rated NEMA 6P, 12, IP68 and IP69K, these sensors protect against corrosion and high-pressure, high-temperature washdowns. Also known as capacitive proximity sensors, they remotely sense both metallic and nonmetallic objects but their strength is in sensing materials such as plastic, ceramic, and clear targets. They’re often used with programmable logic controllers (PLCs) and produce PNP or NPN signal output. To determine the signal output of a sensor you are replacing, use Testers for Proximity and Photoelectric Sensors (not included). They mount flush with the surface of any material, including metal, and are also known as embeddable or shielded sensors. The 4-pole M12 plug connects to cables with sockets (sold separately), allowing you to quickly connect and disconnect the sensor.

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.

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

Also known as inductive proximity sensors, these remotely sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. Sensing distance is based on the type of material being sensed. The distance listed is for mild steel. All are rated IP67 for protection from dust and temporary submersion.

Control and diagnose issues with safety-critical circuits. These relays have a microprocessor that monitors safety components, such as emergency stops and light curtains, and sends a signal to stop the operation if a failure is detected and restart when the issue is resolved. They also help with diagnostic tasks because of their feedback circuit, which allows basic relays to communicate their status back to the safety relay. These relays have a duplicate set of input and output signals, so they’ll still stop the controlled device if one of the inputs fails.

IP20 rated, they have recessed terminals which prevent fingers and other objects from touching live circuits. These relays have been tested to multiple safety standards and can help achieve PL, SIL, or CAT system ratings. They also meet ISO and IEC standards for machine safety.

Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation.
