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.

The steel tape of the MSR 40 utilizes the proven Single-Field Scanning principle with 200µm grating pitch – offering ease of mounting with high achievable angular resolution. Accuracy of the system is ±30 µm/m with an operating temperature of 0 C to +50 C. With these specifications, this encoder is distinguished by its successful operation at high speeds, especially noteworthy for large measurement applications.

The novelty of the MSR 40 encoder is that it links the ends of the steel tape together with one of two joining mechanisms, depending upon the application. Measurement through a full 360° is thus possible. The MOR version uses a steel ring tensioning cleat for encoders mounted to a steel surface thus allowing for thermal expansion; the MER version uses a rubber gasket with a low-profile tensioning cleat for other mounting surfaces.

Depending on the shaft diameter, line counts of up to 20,000 are available on the MSR 40. All versions offer quasi – absolute positioning via distance-coded reference marks or homing via a single reference mark. The MSR 40 is easily mountable and is available in both standard and custom sizes. Custom orders are welcomed.

Housed in a small 4×4 mm QFN package, the low-power encoder is the smallest device in its class. Depending on the readout rate, the current consumption is reduced to µA-levels, e.g. 50µA average at 10 measurements per second – the lowest in the industry.

Only a few passive components and a magnet rotating above the chip are necessary to assemble the encoder systems. The AS5055 performs all angle calculations as well as automatic power-up and power-down on–chip. It only draws current, when a new measurement is requested by the host controller. As soon as the acquisition of a measurement is completed, the AS5055 automatically suspends to power-down.

Josef Janisch, product marketing manager at austriamicrosystems, stated, “This is the industry’s smallest 12-bit magnetic rotary encoder available. It also offers the lowest power consumption due to automatic shutdown and wake-up modes. This is ideal for battery equipment, as it extends battery life. In addition, the industry standard SPI interface offers an easy-to-use connection to common microcontrollers.”

The AS5055 is available in a tiny 4×4 mm 16-pin QFN package, operates from a 3.3 volt power supply, and has an ambient operating temperature range of -20 to +85°C.

Robust, compact and simple installation of the MNI40 make it an ideal choice for a wide range of applications including machine construction, wind power, mobile equipment, material handling lifts and conveying technology. Primary features include:

• Clear indication via LED display (2-color)
• Easy installation and setup
• Quality assurance through complete self-diagnosis
• Long service life

“The LED indications are particularly useful during installation and setup because they provide information on proper assembly.” says David Rubinski, Product Manager. “The integration of the LED also reduces installation time and test equipment requirements, and offers greater potential for reducing overall costs of machine and/or system construction.” explains Rubinski.

The MNI40 utilizes a zero-contact (magnetic) connection between the encoder sensor and magnetic wheel, enabling the MNI40N encoder to measure speed without ball bearings. This eliminates bearing wear due to mechanical forces and ensures long operating life. The sensor includes sensing electronics, housed in a compact IP67 rated enclosure and an elastomer coated magnetic wheel – so contact with water and oil will not damage the encoder system.

HEIDENHAIN’s safety-oriented position encoders with functional safety provide two independently formed position values via a serial EnDat interface. They are certified according to the EN ISO 13849, EN 61508 and EN 954-1 standard for performance level d, safety integrity level 2 and category 3, respectively. The EnDat 2.2 version of these new absolute rotary encoders with serial data transfer offers a singleturn resolution of 23 bits, and a multiturn resolution of 12 bits. The supply voltage range is from 3.6 V to 14 V.

Eight new rotary encoders round out HEIDENHAIN’s 1000 Series including:

–ECN 1013, ECN 1025, EQN 1025, EQN 1035, ROC 1013, ROC 1025, ROQ 1025 and ROQ 1035.

The 7272 EnDat interface module directly interfaces with all Heidenhain EnDat 2.1 rotary encoders, high accuracy angle encoders, and linear scales. The module is digital, two-channel, and bidirectional; enabling it to transmit position values as well as read and update information stored in the encoder, or save new information. For high system reliability, sensor data such as application-specific parameters, compensation tables, error detection, and diagnostic capabilities are made available with this module. Several other features come standard.

EnDat position sensors are bidirectional, and thanks to the serial transmission method supported by AMCI’s 7272 module, only four signal lines are required. They are also self-commissioning, reporting all the encoder’s properties to the controller at power up. OEMs can download application specific data to the encoder’s freely definable memory area. By using the AMCI EnDat interface module, use of these valuable functions is made available through the ControlLogix PLC.

AMCI’s EnDat interface module paired with a Heidenhain EnDat encoder provides a feedback solution for all applications in motion control. Examples of applications that benefit from this pairing include machine tool, printing, and robotics.

Today’s production plants use rotary encoders that are often subjected to high mechanical streses in the form of shock and vibrations as well as high temperatures. It is a fact that the cost of machinery downtime in manufacturing is often all out of proportion to the expense of a simple defective component. And since rotary encoders are key parts of modern machinery and plant control units, it makes sense to equip them with a diagnostic system which continously monitors the internal functionality, therefore providing a basis for initiating maintenance measures in good time. The LEINE & LINDE 800 Series Encoders with ADS™ has often been known to quickly and clearly detect worn-out ball bearings due to poor installation, dust contamination, moisture issues and overheating, to name a few.

Specifically, this LEINE & LINDE automatic self-diagnosis system works by internally monitoring the completeness of the rotary encoder pulses and the correct pulse sequence. Even a single counter difference is registered by the system and reported. This error is relayed as a flashing LED on the rear of the encoder housing. The time of the fault and the corresponding error code are stored in the LEINE & LINDE 800 Series rotary encoder so that the user has the opportunity to read out and analyse the error code via an RS-32 interface once the encoder has been removed. A report can also be displayed directly at the machine if additional wiring is added to an overriding system control.

Conventional rotary encoders are not suitable for harsh environments where corrosive agents are found. This is the case in many industries in which the encoders are exposed to an atmosphere of moisture and chemicals. Such environments will result in corrosion of the encoders’ mechanical parts and may cause loss in operation.
