Presence Sensing Devices

Our Presence Sensing Devices detect the distance, absence, or presence of an object. We offer a wide range of sensing devices to solve your application needs.

Main Image
Photoelectric Sensors

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.

Inductive Proximity Sensors

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.

Ultrasonic Sensors

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.

Tubular Capacitive Proximity Sensors

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.

Swift-E Reconfigurable 3D Sensing

Industry is evolving. Consumer expectations for personalization have resulted in a growing demand for greater product variability, ultimately driving the need for more flexible manufacturing and increased spatial awareness. Our Swift-E reconfigurable 3D sensor enables machine builders and production plants to adapt to these new market trends.

Limit Switches

Our Limit Switches are electro-mechanical devices that consist of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection. Our limit switches work in a variety of applications and environments because of their ruggedness, simple visible operation, easy installation and reliable operation.

Compact/Precision Limit Switches

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.

Hazardous Location Limit Switches

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.

Main Image
Heavy-Duty Limit Switches

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.

Main Image
Metal Limit Switches

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.

Condition Sensing Devices

Our Condition Sensing Devices communicate process variable information to automatically sequence equipment or provide a signal to operators for manual operation. Featuring electromechanical and solid-state solutions, our condition sensors can lower your total operating costs by helping to improve processes and systems, reduce downtime, protect expensive equipment and safeguard operators.

Main Image
Pressure Sensors

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.

Main Image
Temperature Sensors

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

Main Image
Level Sensors

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.

Main Image
Flow Switches

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.

Main Image
Speed Sensing Switches

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.

Identification Devices

Our identification devices are ideal for tracking and documenting products as they move throughout the manufacturing process. Featuring our High Frequency (HF) RFID System and our Code Reader sensors, our identification devices are an effective solution for automotive, material handling, pharmaceutical, and food and beverage industries.

48CR Code Reader

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.

High-frequency RFID

Our Bulletin 56RF High-frequency Radio Frequency Identification (RFID) System is IO-Link enabled and 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. IO-Link makes this a smart Track and Trace solution which easily integrates into The Connected Enterprise, delivering data from the plant floor directly into a control system to help minimize downtime and increase productivity.
