News » Product News Brake controller and monitor needs no sensors
Mayr Power Transmission has developed an intelligent brake control module that not only energises brakes, but can also monitor them without using sensors. The Roba-brake-checker is said to be easy to integrate into existing systems and Mayr predicts that it will open up new possibilities for the monitoring of electromagnetic safety brakes.
Linear actuators with built-in controls simplify set-ups
The Danish linear motion specialist Linak has announced a range of linear actuators with built-in controllers which, it says, will simplify installation and set-up, reduce downtime and maintenance, and deliver greater accuracy. The IC (integrated controller) actuators provide customisable settings and feedback that help to tailor their movements to an application.
Data acquisition module ‘plugs a ControlLogix gap’
US-based Advanced Micro Controls (AMCI) has announced a high-speed, analogue-input data acquisition module for Rockwell Automation’s Allen-Bradley ControlLogix controllers which, it says, fills a gap in the range.
Stopper cylinders are ‘the most powerful on the market’
Festo has launched a series of “affordable” stopper cylinders which, it claims, are the most powerful of their type on the market. The DFSP cylinders can withstand impact forces up to 200% higher than their predecessors.
MEMS-based force sensor is ‘world’s smallest’
The Japanese sensor-maker Alps Electric has developed what it claims is the world’s smallest force sensor, with potential applications for position control in industrial equipment and robots. The HSFPAR sensor uses MEMS (micro-electromechanical systems) technology to achieve its tiny size (2 × 1.6 × 0.66mm).
Nanopositioning drive controls up to ten axes
Aerotech has announced a high-performance nanopositioning piezo drive which, it claims, will allow coordinated motion between up to ten axes of piezo stages and servo axes at much higher rates than other controllers or drives.
End-to-end engineering suite is based on Codesys 3
Wago has announced an integrated engineering tool that supports the entire automation development process, from software design through to machine operation. The e!Cockpit tool, based on the Codesys 3 platform, is said to allow automation tasks to be implemented and run more quickly and cost-effectively.
IIoT-optimised control systems come in three formats
National Instruments (NI) has announced a new generation of embedded control systems in three formats, based on its open, flexible LabView RIO (reconfigurable I/O) architecture. It says that the controllers, which are optimised for the Industrial Internet of Things (IIoT), will help users to build smart industrial systems and machines faster.
Hydraulic clamp and brake has a failsafe action
The German couplings specialist KTR has developed a passive clamping system that can clamp both axial forces and torque. In emergencies, it is even able to act as a brake.
Linear encoder delivers absolute and incremental outputs
MTS Sensors has developed a linear encoder with two output channels – an incremental interface and a synchronous serial interface (SSI) – for position and velocity control of linear and other motors. The Temposonics A-Series Duo encoder can be used to implement measurement systems requiring absolute position feedback, while also producing an incremental encoder signal for monitoring the motor position. The ability to capture absolute position data means that recalibration is not needed.
Dual-axis EtherCat servodrives challenge linear drives
ACS Motion Control has announced a dual-axis EtherCat drive that, it claims, provide a level of performance that was previously only achievable using linear drives, but without the drawbacks of such linear drives. The NPMPM PWM (pulse width modulation) drives are said to be significantly smaller, more efficient, better protected and cheaper, as well as producing less heat.
Alarm system will cut downtime and boost safety
Unitronics has added an alarm management system to its UniStream all-in-one controller, which combines the functions of a PLC and an HMI. Designed to comply with the ISA 18.2 guidelines for implementing, operating and managing alarm systems, the alarm system is supported by a new version of Unitronics’ application development software, UniLogic.
Multi-function power analyser is ‘world’s most accurate’
Yokogawa has announced a power analyser that it claims is the world’s most stable and accurate. The WT3000E analyser – an enhancement of the earlier WT3000 – has a 45–65Hz accuracy of 0.01% of reading, plus 0.03% of range, based on RMS values rather than the waveform peak values used by some manufacturers.
EtherCat motion system allows easy migration from PLCs
Taiwan-based Adlink Technology has announced an EtherCat-based motion control system consisting of a palm-sized master controller, and a modular I/O and motion control system. The combination offers low-cost deterministic control of automated processes and is said to be easy to develop.
Long-range inductive sensors ‘will revolutionise sector’
The German sensor-maker wenglor sensoric has announced a range of inductive sensors which, it claims, will revolutionise the sector. The sensors, which have switching distances up to three times longer than usual, can be mounted alongside each other without causing interference.
