Well known for providing extremely robust encoders for harsh environments, Leine & Linde now offers a new encoder in the hollow shaft 800 series that comes equipped with a one-inch bore size.

Now available in North America through HEIDENHAIN Corporation, this new option from Leine & Linde makes this encoder a strong option for common speed and measurement applications, and of particular use in those that require high vibration and shock resistance.

Named the Leine & Linde XHI 803 model, this intelligent new incremental encoder has an extremely robust housing with a cover of anodized aluminum, and is rated IP 66 (67). It is available with through-going hollow shafts of 12, 16 and 25 mm, and holds line counts up to 10,000. It has HTL, 1Vpp, and TTL outputs.

The 803 encoder, as with all 800 series, is available with Leine & Linde’s Advanced Diagnostic System (ADS) and up to 5-pole commutation. The use of ADS is on the increase as a strong incorporated early warning device.

ATEX versions are available.

HEIDENHAIN Corporation offers a new generation of rotary encoders with IP64 protection, absolute position-value formation, and functional safety, all within a 35 mm diameter housing size.

These small rotary encoders are known as HEIDENHAIN’s 1000 Series and are designed to be especially useful as single-encoder measurement feedback systems in safety-oriented applications.

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 single-turn resolution of 23 bits, and a multi-turn 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 the ECN 1013, ECN 1025, EQN 1025, EQN 1035, ROC 1013, ROC 1025, ROQ 1025 and ROQ 1035.

The New R28i Modular Incremental Encoder is providing state-of-the-art performance in a 28mm package.

The innovative design is self-aligning and self-gapping, and requires no special tooling for installation. Just remove two mounting screws from the motor, slip the encoder on and adjust set screw, push down the cover and insert the connector.

The custom OPTO-ASIC provides a wide range of available resolutions, and sets the standard for resolution and performance. The R28i also can accommodate motor shafts up to 7mm making it suitable for brush motor, step motor, and lead-screw applications.

Features:
• Line count up to 4000
• 2 data channels in quadrature
• Once around index pulse
• 3.3 or 5 volt capability
• Wide operating temp range
• 500 KHz frequency response
• Push/Pull or Line Driver outputs
• Robust mounting
• No installation tooling required

Now available through parent company HEIDENHAIN Corporation is the Leine & Linde 600 Series (a highly robust ø 58 mm fieldbus encoder series), now with DeviceNet™.

This support for fieldbus interfaces extends the range of applications for this already useful absolute rotary encoder. Field bus interfaces based on Ethernet, PROFIBUS or CAN are examples of the communication protocols often used in automation. These interfaces are available on the Model 600 Series absolute coded singleturn or multiturn encoders.

This Leine & Linde series supports 13-bit singleturn or 25-bit multiturn with screw terminal or miniature M12 connection. Mechanically, various shafted- and hollow-shafted versions are available. The DeviceNet™ encoder supports encoder profile revision 2 and the functionality has been fully tested in compliance with the ODVA conformance test.

Overall, fieldbus technology is rapidly gaining acceptance and integration into automation applications worldwide. Based on network topology, system requirements and performance, various types of fieldbus systems are available, all developed and supported by individual standardization organizations. The key principle of fieldbus technology is to enhance device functionality, achieve communication transparency, simplify and standardize installations, as well as limiting the installation and maintenance costs. Sensors, like encoders, with support for various fieldbus interfaces have been available for several years and are increasingly gaining in acceptance and installed market share.

Leine & Linde is well known worldwide for offering high quality, heavy duty encoders of both the incremental and absolute types, are noted for their product robustness and designed to cope with the harshest of environments, such as those with high vibration, dirt and cold temperatures. These heavy, severe duty encoders are suited for drive and measurement applications and are often found in industries such as pulp and paper, forest and wood processing, agriculture, aggregate and mining equipment.
