61 www.drivesncontrols.com July/August 2025 NEW PRODUCTS n maxon has released a PCB module version of its MicroMACS6 multi-axis motion controller, designed to be integrated with custom motherboards for robots and other machines. The six-axis motion controller has no power amplifiers, cutting its weight to less than 10g. The 45mm-long and 30mm-wide module is less than 1cm high. The module delivers the same motion control performance as the MicroMACS6 in a smaller, lighter format. It is suitable for delta, Scara and mobile robots, and can also coordinate machines that rely on kinematics, such as pick-and-place applications. It integrates with DC or brushless DC motor controllers to modulate position, speed and current. It can control axes individually, or perform multi-axis coordination of kinematics groups. It provides functions such as path generator with sinusoidal/trapezoidal profiles, position and velocity control feed-forward, as well as position marker/touch probe. The board has six digital inputs and two analogue inputs, all of which are programmable. It also has four programmable digital outputs, including a 25kHz PWM capability. maxon www.maxongroup.com/en-gb Sensor Technology has developed a digital rotary torque sensor with an integrated incremental angle encoder. It describes the TorqSense SGR523 as a “breakthrough” that “sets a new benchmark for precision in torque and angular position monitoring”. The device has a torque measurement range of 175mNm to 20Nm, an accuracy of ±0.1%, a 400% mechanical overload capacity, an over-range reading capability of 250%, and a digital sample rate of 4,000 samples per second. It uses a non-contact strain gauge technology that eliminates the need for traditional sliprings, and enhances reliability. Its angle encoder delivers up to 10,000 pulses per revolution with a resolution of 0.009 degrees, making it suitable for applications that need precise torque-angle analysis, such as automated assembly, mechanical testing and process control. Analysing plots of torque versus angle can reveal mechanical anomalies such as rotational stiction or thread damage. The dual-parameter monitoring can be crucial for quality assurance in processes such as tightening bottle caps and fastening bolts. The sensor's ability to monitor torque at specific shaft angles can help to identify potential issues in control applications. The high-resolution angle measurement also facilitates precision motion control, allowing better management of inertia in motion platforms and improved safety in automated machinery. Sensor Technology www.sensors.co.uk Emis has announced a threephase EMI filter with neutral, designed to be used where noise may arise not just from phase wires but also from neutral line. The TMF4233 filter is a compact, lightweight and space-efficient design optimised for industrial machinery and designed to handle currents up to 600A. It provides good suppression of high-frequency noise from switching power supplies, motors, inverters and other equipment, and is ideal for complex machines where the insulation resistance needs to be higher than 1MΩ. The chassis-mounting filter operates at 520V AC at up to 600A over the 50/60Hz frequency range. EMI Solutions https://emisglobal.com EMI filter handles systems with noise on the neutral line Cost-cutting multi-axis control module weighs less than 10g Combined torque and angle sensor is ‘a breakthrough’ HBK has announced an edge amplifier for industrial and weighing processes. The digiBox amplifier is said to combine precision, connectivity, durability and flexibility. It can be placed close to sensors and offers realtime processing of data. HBK says the amp “uniquely” combines IT/OT connections on a single device. It can extract measurement data, in parallel to being connected to a machine’s PLC. Using protocols such as MQTT and openDAQ, the digiBox can be integrated with cloud applications, to perform DAQ analysis and to transmit process data to productivity software. The IP67-protected modular amplifier is available in two- or four-channel versions. There are two firmware versions: one for applications such as press-load monitoring and assembly lines; the other for weighing. HBK www.hbkworld.com Rollon has launched a size 200 ballscrew-driven linear actuator in response to a growing demand for actuators capable of handling higher loads and delivering longer strokes, without compromising precision or reliability. The precision actuator is part of Rollon’s compact TH series, known for its positioning accuracy, with repeatabilities of ±5μm. The actuator is guided by two or four preloaded re-circulating ball bearing blocks with ball retainer technology, running on parallel rails for optimal rigidity and smooth movement. The actuators are said to maintain precision and stiffness throughout their operation, helping ensure consistent quality and application efficiency. Sealing strips protect internal components, while scrapers and lip seals protect the ball bearing raceways against contaminants. There are dedicated lubrication channels for the ballscrew and the bearing blocks.
