Portescap pairs superior accuracy and feedback positioning
Portescap introduces the new M Sense B Encoder, designed specifically for applications that require high accuracy in a compact design. The M Sense B is the first in its class to offer accuracy in the range of 1-1.5 degrees, covering a resolution band of up to 1024 lines with an integrated line driver resulting in […]
Programmable Encoders: The Next Generation
by Jarrod Orszulak, Product Manager, POSITAL-FRABA The latest programmable encoders offer both incremental and absolute functionality on one hardware platform and can be programmed with a WiFi connection. Programmable incremental encoders have become more common recently. This is largely due to the fact that the measurement characteristics of the device (number of pulses per rotation, […]
Rotary magnetic sensor delivers unsurpassed ruggedness
The new SIKO MSK320 ZM magnetic sensor has a durable metallic housing. Suitable for rotary measuring tasks (such as measuring the drive shaft speed on machine tools, woodworking machines and textile machines) it also works on large-scale outdoor applications (as on forestry or stone machinery). More after the jump. Engineers can get the new sensor is already available and test it for free by contacting SIKO. […]
Tiny kit-style encoder: New option for linear measurement
A tiny linear encoder from RSF Elektronik is an MS 15 optical kit-style with the smallest mechanical profile in the industry. Available in North America through HEIDENHAIN, the encoder works in machinery for metrology, semiconductor, medical and automation. The MS 15 optical kit-style encoder is 36 x 13.5 x 14.8mm in size, and provides a 40 […]
FAQ: What is the difference between absolute and incremental encoders?
Rotary encoders track speed and position. Absolute and incremental encoders both do this, but operate differently and have different methods of implementation. Rotary incremental encoders work by generating a series of pulses during movement. The encoder disc (sporting marks or slots) attaches to a power-transmission shaft, and a stationary pickup device mounts nearby. When the […]
FAQ: What are ways to wire an incremental encoder into a motion system?
There are two ways to wire an incremental encoder into a system. One is single-ended wiring and the other is differential wiring. In single-ended wiring, each channel needs only one wire. Channels are any data streams that the encoder produces. For example, a common quadrature encoder has two channels—A and B—to track speed as well […]
Compact servo motors with MILE inductive encoders by maxon
MILE stands for “maxon’s Inductive Little Encoder.” The operating principle is based on the measurement of high-frequency inductive fields, which generate Eddy currents in an electrically conductive target disk. The advantages of a high-frequency inductive measuring method in comparison with classic encoders are: High robustness against dust or oil vapors. This means that no additional […]
Beckhoff compact multi-axis servo system with high maximum control speeds, fast installation
The new Beckhoff AX8000 multi-axis servo system, with a compact form factor for space-saving control cabinet installation, enables high-precision positioning and machining processes with extremely short control cycles. Additional features include fast installation and commissioning by simply plugging together the desired axis modules, as well as One Cable Technology (OCT) and the direct integration of […]
Hall-effect position sensors withstand off-highway use
The new Model 9970 Hall-effect position sensor from BEI Sensors ships within two weeks and features a 50-mm mounting hole spacing for drop-in compatibility with existing installations. It’s IP67 and IP69K rated non-contacting technology, so the sensor withstands harsh environments. A 1.5 Series AMP Superseal connector is standard. With life to 35 million cycles and a temperature rating from -40° to […]
