Encoders that provide incremental position measurements (whether rotary or linear) output two signals, or channels, typically termed “A” and “B,” to provide position and direction information. These output signals can be in the form of analog sine and cosine waves or in the form of digital square waves. Those that produce digital output signals are typically […]

THK OMNIedge System provides predictive failure detection of linear motion components
THK’s innovative OMNIedge System enables predictive failure detection of linear motion components for improved productivity and reduced maintenance costs. The OMNIedge network sets up automatically and sensors are simply installed on existing components for convenient and easy remote monitoring of operating conditions. Data is securely collected through a dedicated closed IoT network for analysis and […]
What is a linear variable differential transformer (LVDT)?
In previous articles, we’ve covered a variety of technologies for measuring linear position: magnetic and optical encoders, magnetostrictive sensors, and even measuring systems integrated into linear guide systems. Another technology for measuring absolute linear position is the linear variable differential transformer (LVDT). A linear variable differential transformer is an induction-based measuring system that consists of […]
NewTek sensor addresses requirements for custom LVDT position sensors
As many industries continue to experience supply chain challenges, NewTek Sensor Solution is addressing more requests for custom LVDT sensors in short timelines in meeting unique and demanding position measurement requirements for applications in a range of industries including oil/gas, packaging, manufacturing and power generation. As travel bans, border closures and regulations associated with COVID-19 […]
AutomationDirect adds inductive linear position transducers
Linear Variable Inductance Transducers (LVITs) from Alliance Sensors Group convert the linear displacement of an object into a proportional electrical signal output of 0 to 10 V or 4 to 20 mA (depending on model). LVITs are contactless devices designed for dimension or position measuring applications where the sensing element cannot be attached to the […]
Balluff’s new magnetic encoders easily integrate with Siemens motion control systems
Balluff’s new absolute magnetic linear encoders with Siemens Drive-Cliq interface are designed to integrate perfectly into Siemens motion controller environments. Plug-and-play installation makes incorporating them into the drive system easy. The controller automatically detects the sensor and its basic settings. Its automatic status monitoring continuously checks the measurement quality, detecting any mechanical position shift during […]
New linear measurement solution offers programmable option
Encoder Products Company’s (EPC) new addition to their line of linear measurement solutions offers users a spring-loaded mounting bracket combined with a choice of measuring wheel. They then select the encoder to meet their exact application requirements. With up to 10 lb of adjustable spring tension, this spring-loaded mounting bracket fits 2.5-in. shafted encoders with […]
Wire-actuated encoder features 12-m measuring length
The new SG121 wire-actuated encoder from SIKO features measuring lengths up to 12 m with an installation depth of just 70 x 85 x 105 mm. The robust aluminum housing, coupled with impact-resistant plastic, survives even the harshest of operating conditions. Temperatures between -40 and +80°C, high shock and vibration loads, dirt, dust and water […]
Boosting productivity with the right direct-drive motor and linear-motor feedback
Feedback options for linear motors and direct-drive torque motors abound. The most common employ optical, magnetic, capacitive, or inductive measurement. Here we explain how the key application parameters of precision, cost restrictions, and insensitivity to mechanical characteristics and environment dictate which technology is most suitable. By Steffen Preg | CEO • SIKO Products Inc. Machines […]
Space-saving integrated guide, linear encoder from THK
The new Type SHS-LE from THK integrates the global standard THK Type SHS LM guide with a THK linear encoder (linear position sensor). This combined model allows for compact machine designs that require less assembly time. THK’s Type SHS Caged Ball LM Guide performs with high speed and precision. Each row of balls is arranged […]
