All interpolation, automatic gain control (AGC), and signal processing is performed […]
Encoders + sensors (linear) + I/O
Linear encoders improve accuracy
by Product Management Dept., HEIDENHAIN CORP. Linear encoders boost accuracy by correcting errors downstream of mechanical linkages. Linear encoders track axis position without intermediate mechanical elements. The encoders even measure transfer errors from mechanical linkages (such as rotary-to-linear mechanical devices), which helps controls correct for errors originating from the machine. Thus, this feedback lets controls […]
New shaft protected position sensors
Novotechnik, U.S. introduces the LWX-003/004 Series of position sensors designed for extremely harsh environments. The all-metal sensor shaft features a pressure equalization valve and the LWX-004 version also provides rod protection over its range of motion with an SS304 alloy, 0.9 mm thick stainless steel shield. The LWX Series’ differential pressure compensation system compensates for […]
How encoder resolution is determined
Resolution is a fundamental specification and one of the most important factors when selecting an encoder. For linear encoders, resolution designates the number of measuring units per distance (inch or millimeter), whereas for rotary encoders, it refers to the number of measuring units per revolution (also called pulses per revolution, or PPR) or per degree of […]
Using linear and rotary Hall-effect and reed sensors
by Gwenn Gmeinder, N.A. Busines Development Manager, Sensor Products, Littelfuse Analog and digital sensors are accurate and reliable over the long term. Here we explain how to choose them for industrial automation and motion-control applications. We define and describe the benefits of digital and analog sensors and give industrial examples. Then we apply design principles […]
New technologies for linear motion: Forgiving linear encoders and more
From nanometer resolution to high-force actuation, components for linear motion systems are changing with the times. Linear motion components such as encoders and actuators are evolving to meet the demands of new applications and industries. New demand in areas like medical devices, for instance, calls for more nimble, smaller components adaptable to new environments and […]
Linear encoders for motion applications
Whether a linear system uses servo or stepper motors, adding a linear encoder can improve the performance of the machine and the quality of the process. In servo applications, the motor’s rotary encoder monitors its speed and direction, but a linear encoder monitors the load’s actual position. When stepper motors are used, position monitoring is especially important, […]
A user’s guide to sensors and switches
Users have an array of choices when it comes to choosing sensors for electromechanical actuators. Some actuator manufactures offer one or two varieties of sensors as standard options, depending on the construction of the actuator and its most common uses, while others leave the selection entirely to the user. Whether you’re choosing among the options […]
