BEI Industrial Encoders
SwiftComm Wireless Interface System
BEI Industrial Encoders has rolled out a wireless interface system for incremental encoders. Called SwiftComm, the system includes a transmitter-receiver pair that communicates using a point-to-point, frequency-hopping 2.4 GHz RF protocol. The proprietary protocol includes a broad security code range, data encryption, handshaking, interference recovery and error checking. SwiftComm is intended for use in applications such as factory automation, printing, crane, hoist and mining equipment that would require a long cable run for conventional encoders.
SICK STEGMANN Inc.
VFS 60 Motor Feedback Systems
The VFS 60 Motor Feedback Systems from SICK STEGMANN Inc. feature a nickel code disc designed to withstand harsh industrial environments and ac induction motor applications that can give models with glass code discs trouble. Packaged in an industry-standard 60 mm housing, VFS 60 encoders mount to ac induction motors and deliver up to 10,000 ppr at operating temperatures up to 100C — versus 70C for many glass- or plastic-disc models. They also offer shock resistance to 70 g/6 ms and vibration resistance to 30 g up to 2,000 Hz. As an option, the encoders can be purchased with a user-programmable PPR, zero pulse set and type of electrical interface.
