Encoders

SICK (www.sick.com) has introduced its first rotary encoders that feature a built-in Ethernet IP interfaces at the SPS/IPC/Drives show in Germany. The AFM60 multi-turn and AFS60 single-turn absolute encoders utilize the Ethernet interfaces to monitor networks and for diagnostics. Its integrated diagnostic functions include monitoring the internal temperature... [Read more]

Posital (www.posital.com) has integrated a bit parallel interface to its range of OCD optical encoders, ensuring a reliable, fast transfer of angular position into higher level controllers. These make them suitable for use in remote regions, as they offer easy diagnosis options that come with simple tools. The OCD optical encoders are based on a single... [Read more]

Jena, Germany – NUMERIK JENA, sister company of HEIDENHAIN, now offers a line of linear and rotary encoders that are non-magnetic and that have been tested in environments up to 6 Tesla and have no influence on the machine environment. The encoders also can withstand this high magnetic environment without loss of accuracy or resolution and are mechanically... [Read more]

Baumer has unveiled its latest HS35 family of incremental hollow shaft encoders, which include a fully-programmable version, for speed control applications and heavy-duty positioning. The rugged encoders are specifically designed to withstand high-pressure cleaning, shocks of up to 200 g and ambient temperatures ranging from -40°F to +212°F. Baumer... [Read more]

Baumer (www.baumer.com) has unveiled its small absolute encoder series MHAD, which seamlessly combines the functional capabilities of an absolute encoder with the product benefits of narrow dimensions. With a very compact design, the encoder measures only 50 mm in diameter and 20 mm deep. This makes the encoder easy to fit into tight areas where installation... [Read more]

Balluff (www.balluff.com) has announced that its latest S2E Rotary BML rotary encoder offers a new level of positional information, making it suitable for applications such as speed control, conveyors and angle measurement. Easy to set up and accurate, this rugged rotary encoder comes at a lower cost and is provides more effective improvement on traditional... [Read more]

BEI Sensors (www.beisensors.com) has unveiled a space-saving and ultra rugged industrial encoder that meets the required standards and certifications for use in potentially explosive environments. Model HS52 is the industry’s first ATEX and UL rated explosion proof hollow shaft encoder. This rotary encoder can be operated directly in Zone 1 and Division... [Read more]

Incremental encoders, like absolute encoders, are used to track motion as well as to determine speed and position. Incremental encoders generally supply square-wave signals in two channels, A and B, which are offset by 90 degrees, or out-of-phase by 90 degrees. This helps in determining the direction of rotation. The output signals of an incremental... [Read more]

Encoders can be either absolute or incremental. Absolute encoders have a unique code for each shaft position. Or in other words, every position of an absolute encoder is distinctive. The absolute encoder interprets a system of coded tracks to create position information where no two positions are identical. Another feature is that absolute encoders... [Read more]

Posital (www.posital.com) has announced that its Magnetocode (MCD) absolute rotary encoders now features a new hollow-shaft variant of the MCD encoder, making the devices easier to mount on shafts up to 20 mm in diameter. Featuring excellent accuracy, adaptability and reliability, the new devices are offered with digital or analog electrical interfaces.... [Read more]
