Honeywell Sensing and Control Zephyr Analog Airflow Sensors

Honeywell Zephyr™ Analog Airflow Sensors: HAF Series-High Accuracy, provide an analog interface for reading airflow over the specified full scale flow span and temperature range. Their thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow.

Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases. They are available in standard flow ranges and are fully calibrated and temperature compensated with an on-board Application Specific Integrated Circuit (ASIC).

The HAF Series is compensated over the temperature range of 0° C to 50° C [32° F to 122° F] and operates across a temperature range of -20° C to 70° C [-4° F to 158° F]. The state-of-the-art ASIC-based compensation provides analog outputs with a response time of 1 ms.

These sensors operate on the heat transfer principle to measure mass airflow. They consist of a microbridge Microelectronic and Microelectromechanical System (MEMS) with temperature-sensitive resistors deposited with thin films of platinum and silicon nitride. The MEMS sensing die is located in a precise and calculated airflow channel to provide repeatable flow response.

Zephyr sensors provide customers with enhanced reliability, analog accuracy, repeatable measurements and the ability to customize sensor options to meet many specific application needs. The combination of rugged housings with a stable substrate makes these products extremely robust. They are designed and manufactured according to ISO 9001 standards.

Pepperl+Fuchs High Resolution Ethernet IP Encoders

Pepperl+Fuchs introduces EVM58 Ethernet IP Encoders. Available in single or multi-turn configurations, these rotary encoders provide highly accurate absolute machine position or velocity feedback to the system controller via an industry-standard Ethernet/IP interface. Ethernet IP Encoders are also compatible with a variety of PLC controllers, including industry-standard PLC products from Rockwell Automation, Allen Bradley and Schneider, making them well suited for material handling, automotive and general factory automation applications.

“Ethernet IP Encoders deliver basic resolution up to 8192 steps per revolution (13 bits) and up to 4096 revolutions (12 bits), for overall resolution up to 25 bits. These encoders provide a very high positional count value, which is ideal for precisely dividing very long traverse distances into small measurable values,” says Dave Rubinski, Product Manager.

Ethernet IP Encoders come in standard 58mm diameter housings, with a solid 10mm shaft, and clamping flange design. Diagnostic LEDs provide visual status indication to help users quickly correct problems and keep machines up and running. M12 d-coded connectors simplify operation and are used to power, and facilitate communication to and from, the encoder. Ethernet IP Encoders can be used with cable pull devices to determine linear position feedback and transmit that feedback back to the controller.

In addition to Ethernet/IP, Pepperl+Fuchs offers a complete family of encoders for CANopen-, DeviceNet-, PROFIBUS- and AS-Interface operation.

IDEC HE6B Three-Position Enabling Switch

IDEC's new HE6B three-position enabling switch is ergonomically designed to work where human interaction is required to turn on a machine or robot while the user is in a potentially dangerous area. Typically, enabling switches are installed in grip switches or pendant stations. This 3-position enabling switch not only turns a machine on when pressed, but also turns machines off when over pressed or squeezed, as long as the switch is installed correctly in an adequate safety circuit. Two contacts are provided so that even if one contact fails, the other can disable machine operation. Functionality is the same as all previous HE devices and meets all stringent requirements to meet IEC standard 60947-5-8 for this class of products. A waterproof rubber boot, available in yellow or black, provides IP65 protection.

3 –Position Operation, how it works: By holding an enabling switch, an operator can avert danger when a machine operates unexpectedly. When the panicked operator either releases or grasps tightly the enabling switch, the switch disables the machine operation in either situation.

Phoenix Contact LINETRAB LIT Compact Surge Protection for MCR Technology

Transients induced onto the signal lines often cause costly damage and downtime. Therefore, surge protection for MCR technology is indispensable. At the same time, there is a demand to save space and reduce wiring time, all at a minimum cost.

Phoenix Contact's new LINETRAB LIT are space-saving surge protection devices for the MCR technology. Up to 4 signal cores can be protected on a design width of just 6.2 mm. Three/four-wire measurements can thus be realized with just one arrester, thus saving space in the control cabinet.

Even with its low article variety, the LINETRAB product range provides the ideal solution for a wide range of applications such as binary, analog and intrinsically safe circuits.

LIT 1x2-24 is a surge protection device for a floating signal circuit. The cabling system enables simple and time-saving wiring to INTERFACE components and PLC controllers.

LIT 2x2-24 provides protection for two floating signal circuits.

LIT 2x1-24 is a surge protection device for two wires with a common reference potential.

LIT 4x1-24 protects four wires with a common reference potential against surge voltages on a design width of just 6.2 mm.

Phoenix Contact PSR-ESAM 3x1 and 2x1 Safety Relays

Phoenix Contact has added four new part numbers to their safety relay range. One version has three redundant normally open (NO) contacts and one normally closed (NC) status contact. Another version has two redundant NO safety contacts and one NC status contact. Both are available in either spring or screw connection.

These new relays can be reset with either a monitored manual or automatic reset. Previous relays required you to choose which type of reset (monitored manual or automatic) is required. The PSR-ESAM relays eliminate the need to understand the reset circuit, simplifying your selection.

Phoenix Contact PSR-FSP Process Safety Relay

The PSR-ESP (2981020) is Phoenix Contact’s original Safety Integrity Level (SIL)-rated or process safety relay. Some of the largest process companies in the world currently use this relay. It has also been Phoenix Contact's best-selling safety relay over the last several years. Experience with these high-profile process customers has led to a smaller, more advanced and a slightly less expensive relay, the PSR-FSP.

  • Completely compatible with the “test pulses” occurring on safe PLC/DCS outputs
  • Inrush requirement is limited for safe PLC/DCS output compatibility
  • Built-in fuse for the safe output contact
  • One normally open redundant safety output and one normally closed status output
  • Just 17.5 mm wide
  • SIL 3-rated: SIL reliability data is available on the instruction sheet in the box.

Rittal CP-C Support Arm System

Machine controls often need to be easily moved into a position for use, adjusted to the user's height, then pushed out of the way when the operation is complete. That's when a support arm system is ideal — get the needed changes made, then get the enclosure off to the side.

Rittal leads the way with innovative pendant arms and the housing. For heavier applications the Rittal CP-XL support arm system is ideal, and for lighter loads you can use the CP-L. Right in the middle is the CP-C, which has been configured for use with Rittal's OptiPanel and Comfort Panel cabinets and complements the design of these enclosures for a professional, finished look.

Like the other support arm systems offered by Rittal, the CP-C pendant arms can be mounted from the floor, off the side of a machine and from above. Need an elbow to create a 90 degree turn? It's available. What about a hinge in the middle? You can get that too. Want to lock the enclosure into position, but have the flexibility to rotate the cabinet if needed? No problem.

Cable runs are also easy with a large interior channel which is roomy enough for VGA or DVI connectors. Need to separate the cables? There is a partition strip that makes this simple. Automatic electrical bonding means no ground straps and smartly designed bases and hinges make adjustments to the rotation angle easy.

The Rittal CP-C system’s smart modular design and intermediate high load bearing capacity allows configurations that are ideal for practically every situation.

Pepperl+Fuchs Multi-Axis Photoelectric Sensor Mounting Brackets

Pepperl+Fuchs introduces OMH-RL31-06 Mounting Brackets. These brackets provide an affordable means to flexibly mount Pepperl+Fuchs Series 31 photoelectric sensors in multi-axes alignment applications. They feature half-clamp mounting in which the bracket fastens on a 12 mm (0.5 in.) diameter rod or bolt. Once fastened, the half-clamp can be rotated 360° around the rod or bolt to best align the sensor to satisfy the specific application requirements.

“These brackets make it easier to align and position photoelectric sensors for faster changeover than is possible with standard right-angle brackets. They also have a protective shroud that covers two sides of the sensor housing for more protection,” says Jeff Allison, Product Manager. These benefits can help reduce costs and maximize productivity in material handling, overhead door and any number of general automation applications.

Pepperl+Fuchs is a world leader in the design, manufacture and application of high quality factory and process automation products and services. Pepperl+Fuchs pioneered the development of proximity sensors 50 years ago, and has set the standard for innovation and quality ever since.

Turck Inclinometers with CANopen Interface

TURCK has expanded its broad offering of inclinometers with the addition of a new dual axis inclinometer sensor with a CANopen interface for angular tilt detection. These sensors have angle measurements of ±10, 45 and 60 degrees. Inclinometer sensors may be used in a wide variety of industries to solve unique feedback requirements where the customer needs to level platforms, control tilt angle or control a dancer.

About Inclinometer Technology
The new TURCK Q42 inclinometer measures angular tilt in reference to gravity. At the heart of the TURCK Q42 inclinometer is a MEMS (micro-electro-mechanical system) device that incorporates a micro-electromechanical capacitive element into the sensor that utilizes two parallel plate electrodes, one stationary and one attached to a spring-mass system. Movement causes acceleration that produces deflection in the non-stationary electrode. This results in a measurable change in the capacitance between the two plates that is proportional to the angle of deflection. All measured values and parameters are accessible via the object directory. The micro board design in the MEMS technology allows for a compact, precise inclinometer in a very robust, industrialized package.
