With the TRK38, TWK introduces an ultra-compact single-turn magnetic encoder developed with safety-oriented applications in mind. With a diameter of only 38 mm and a length of also 38 mm, and a weight of 60 g, the sensor is suitable for mounting in confined installation spaces. The TRK38 detects position and speed in a safety-oriented […]

Multiturn absolute encoders with line driver feature integrated referencing
In combination with brushless dc servomotors, the new magnetic AEMT-12/16 L absolute encoder from FAULHABER delivers absolute angle information with a preset multi-turn resolution of 16 bits (65,536 revolutions) and a single-turn resolution of 12 bits (4,096 steps) for commutation, speed control and motion control. This position data can be queried by an SSI Interface […]
Smarter, faster angle encoders improve direct-drive motor performance
HEIDENHAIN has introduced smarter and faster versions of the RCN absolute angle encoders series for use in machine tools requiring high speed, accuracy and contamination resistance. The new models RCN 2001, 5001 and 8001 are especially useful with fast rotating axes and direct-drive motors because the permissible speeds are up to three times higher than […]
Multi-turn encoders for miniature motors require no battery backup
POSITAL’s new 22-mm multiturn kit encoders are high-precision multiturn absolute position feedback devices for miniature motors and drives. While motion feedback devices for small motors have previously been limited to single-turn or incremental encoders, the new compact kit encoders from POSITAL now provide full multiturn measurement capabilities – without any need for backup batteries. The […]
What is dual-loop control for servo systems and when is it used?
In servo-driven systems, feedback for position, velocity, and/or torque control is typically provided by a rotary encoder or resolver mounted to the motor. But mechanical components and connections in the drivetrain — such as gearboxes, ball screws, and couplings — are not perfectly rigid and introduce backlash, compliance, and windup into the system. This lack […]
Feedback on stepper motors for better positioning and holding (and less ringing)
Feedback-equipped stepper motors are not a complete substitute for servomotors, but they can provide a reliable alternative for many real-world applications. These motion-design solutions improve machine performance without breaking the bank. By Jim Stevens • Product Specialist | POSITAL Inc. Stepper motors are a top choice for many motion and position control applications. They’re available […]
Panel-mount encoder series now with plastic shaft options
CUI Devices’ Motion Group has added plastic shaft actuator options to its C14 family of optical panel mount encoders. Ideal for a range of ventilator and associated medical applications, these 2-bit, quadrature output encoders feature incremental resolutions of 16 or 32 PPR and multiple termination types including cable, header, PCB pins, and solder holes. All […]
New absolute encoder for harsh environments from Netzer Precision
The VLX-60 is a new member of the VLX series of Electric Encoders, a product line based on Netzer Precision Motion Sensor proprietary technology. Products in this series are characterized by a number of features including: Low profile (<10 mm) Hollow shaft (stator/rotor) No bearings or other contact elements High resolution and unparalleled precision Low […]
Encoder Products Company offers draw wire motion feedback solution
Encoder Products Company’s (EPC) new LCX Series draw wire units work with EPC encoders to accurately measure position and provide motion feedback in motion control applications. The LCX Series of Draw Wire solutions is manufactured for EPC by our German technology partner and offers wire lengths from one to 42.5 meters in length. “The maintenance-free […]
What are geared cam limit switches?
Electromechanical switches are often placed at the ends of linear axes to indicate the limits of travel. But for applications with rotary — rather than linear — motion, geared cam limit switches can perform a similar function by tracking rotations of the motor shaft and triggering switches to stop movement when the specified number of […]
