Sensors & Switches

Our Photoelectric Sensors use a beam of light to detect the presence or absence of an object. This technology is an ideal alternative to inductive proximity sensors when you require long sensing distances or when the item you want to sense is non-metal. Our photoelectric sensors satisfy applications found in many industries, such as material handling, packaging, food processing, and transportation. For your specialized applications that require a non-standard connector or cable, we can customize the sensor connections.

Our Inductive Proximity Sensors detect metal objects without touching them. This technology is used in applications where the metal object to be detected is within an inch or two of the sensor face. Our sensors can be used in light-duty packaging applications and the punishing environments on automotive welding equipment or the harsh washdowns in food processing plants.

Our Ultrasonic Sensors are self-contained solid-state devices designed for non-contact sensing of solid and liquid objects. For many applications, such as monitoring the level of water in a tank, ultrasonic technology lets a single device to do a job that would otherwise require multiple sensors. Our sensors are available in several sensing ranges and styles with either an analog or discrete output depending on the model.

Our Bulletin 875C and 875CP Tubular Capacitive Proximity Sensors have an adjustable sensing distance and are equipped with two status indicators to show power and output. 875C sensors are shielded and housed in a nickel-plated brass barrel. 875CP versions feature a plastic barrel and are unshielded models. Both versions meet NEMA 12 and IP67 (IEC 529) enclosure standards. Connection options include PVC cable, and micro and pico quick-disconnect.

Our compact, precision, and small precision limit switches withstand the rugged environments that industrial applications demand. Each style uses industry standard mounting dimensions and operating characteristics. Our 802B family of limit switches can be mounted in areas that traditional NEMA limit switches cannot, due to their size and mounting options.

Our Hazardous Location Switches are designed for use in applications such as refineries, distilleries, grain elevators and flour mills where dangerous gases or other materials may be present.

Our Heavy-duty Limit Switches are ideal for applications that need heavy duty pilot ratings, small size, and a high degree of versatility. We offer a wide variety of operating heads and operating levers.

Our Bulletin 802K 30 mm Metal Limit Switches have a range of options including snap action, slow break/make with 2, 3 or 4 contact configurations and a choice of actuator heads. You can rotate the head in 90° increments before installation for easy mounting. The 802K is ideal for non-safety applications.

Our Pressure Sensors include rugged, industrial-grade, electromechanical pressure controls as well as solid-state pressure switches for any application. Our control products support multiple switching and output requirements. You can use them in a variety of applications and environments.

Our Temperature Sensors and Process Controllers offer quick setup and provide precise temperature management and control for a variety of applications.

Our Level Sensors are heavy-duty industrial control devices. They open and close contacts in response to changes in liquid level. Level sensors are available in five different styles with both motor and pilot duty contact ratings.

Our Bulletin 839E Flow Switches monitor and display liquid media flow rate from 0.03 to 3 m/sec (0.1 to 9.84 ft/sec). This sensor measures both flow and temperature and is available with two different probe insertion lengths.

Our Bulletin 808 Speed Sensing Switches provide an electrical contact signal at a determined speed for plugging, anti-plugging, speed sensing, and direction of rotation.

Our Bulletin 48CR Code Readers are the smallest industrial code readers on the market. These rugged, compact solutions can decode 1D, 2D and Direct Part Marked (DPM) codes and they can even successfully read damaged and incomplete symbols. The 48CR supports Ethernet/IP™ and can be configured through either the Studio 5000 Logix Designer application Add-on Profile (AOP) or the embedded WebConnect visual browser.

Our 56RF High-frequency Radio Frequency Identification (RFID) System is ideal for tracking and documenting products as they move through the manufacturing process in light-duty industrial applications. The RFID system tags, transceivers, and interfaces are designed to the ISO 15693 open standard for high frequency. 

Absolute Encoders retain your position data during loss of power. They are excellent choices in systems that require failsafe operation. Our magnetic encoders directly connect to DeviceNet™ for advanced functionality with reduced wiring cost. Our sine/cosine encoders provide absolute feedback for position control and high resolution incremental feedback for speed control. Our Integrated Motion on EtherNet/IP encoders leverage CIP Sync, a time synchronization extension that is fully compliant with IEEE 1588. You can use our single-turn encoders for reliable readouts in harsh conditions.

Our Incremental Optical Encoders produce digital output related to the position of a rotating shaft, providing feedback elements in closed-loop control systems. You can use our encoders with external electronics, such as counters, to accumulate data to determine position, speed, and direction. Use these encoders when position retention is not required during a loss of power.

Our Pneumatic Rotacam™ Hazardous Location Switches provide positive-acting isolation of a machine's compressed air supply. The Pneumatic Lifeline™ 4 Hazardous Location Switches are rope-operated pneumatic safety switches that guard exposed pneumatic machinery and conveyor equipment. These switches are immune to machine vibration.

Our Guardmaster Explosion-Proof Switches have sealed flameproof contact blocks, making them suitable for use in European Zone 1 and Zone 2 hazardous environments. They retain the safety features and operating principles of the conventional Guardmaster® switches. All the Guardmaster Ex switches conform to the exacting standards required by the European harmonized standards.
