61 n NEW PRODUCTS April 2023 www.drivesncontrols.com Sick has announced a range of linear encoders that open up its non-contact, wear-free magnetostrictive technology to industrial users for the first time. The Dax encoders measure absolute position, so no reference runs are needed. They are designed to make specification quick and easy, using an online tool with options for additional customisation. Measuring ranges are 50–2,500mm, configurable in 1mm increments. The encoders save space in new machinery, as well as being backwards-compatible with existing installations. They can be customised to work with all common types of magnet. There are three housing options: one for integration into hydraulic cylinders; a low-profile type with block magnets for tight spaces; and a version with a slider that guides the position magnet, simplifying alignment during mounting. They have enclosure ratings of IP65 and IP67. The online configurator guides users through the specification process to generate a part number and an order in a few steps. Application-specific versions can be generated quickly. The encoders offer analogue outputs of 0-10V DC or 4-20 mA. A CANopen variant gives access to diagnostic capabilities to monitor sensor parameters and environmental conditions. Diagnostics can also output speed and time profiles to monitor for changes in machine performance over time. Sick UK www.sick.co.uk Panasonic has announced a laser distance sensor that can detect reliably at distances of up to 3m using time-of-flight technology. The HG-F sensor can be installed at some distance from the object being measured, allowing employees, or machines such as robots, to move around freely. The long range also allows large workpieces, or items of different heights, to be measured, and because the beam spot is smaller than for adjustable-range sensors, the sensor can operate through narrow gaps. The class 1 laser sensor needs no special protection. Its visible beam allows measuring positions to be recognised at a glance, which is helpful when setting up the sensor. A special installation mode simplifies commissioning by amplifying the light intensity. The sensor has a rugged 20 x 44 x 25mm aluminium case. The desired measuring distance can be set on the sensor, with a built-in display showing the desired clearance. Panasonic Industry Europe http://industry.panasonic.eu New diagnostic modules from ifm electronic allow vibration monitoring and analysis to be carried out in the field, eliminating the need to send signals from accelerometers to control panels. The robust VSE9xx modules have an IP67 protection rating, and can be mounted almost anywhere without extra protection. They use M12 connectors for speedy installation and retrofitting, and are compatible with all common acceleration sensors. The modules accept inputs from up to four accelerometers, and have two auxiliary inputs – one pulse, one analogue – for collecting extra information, such as speed and temperature. They accept accelerometer inputs in the range 0–12kHz, with a sampling rate of 100kHz. The modules evaluate the signals from the sensors in real time and provide alarm outputs. They can also supply data for further analysis by software from ifm or third parties. There are four versions for different networks: TCP/IP; Profinet; Ethernet/IP; and Modbus/TCP. All provide separation between automation and IT networks. Ifm electronic 0208 213 2222 www.ifm.com/gb/en US-based Performance Motion Devices (PMD) has released a programmable drive for controlling brushed and brushless DC motors, and stepper motors, up to 500W. The Ion 500 digital drive, available in the UK from Inmoco, delivers 20A continuous current (30A peak) for single-axis applications. On-board programming enables distributed control, which can improve motion performance, and also frees up central processing with motion functions executed at the required axis. PMD’s Magellan chip allows standalone control, which can remove the requirement for a separate controller, cutting costs as well as creating a small, lightweight motion control system. Capabilities include profile generation, PID position loop closure, PWM signal generation, and field-oriented control. The functions include trajectory generation (including trapezoidal and S-curve pointto-point profiles), velocity contouring and electronic gearing. The drive can also perform position servo compensation, step motor stall detection, and microstep generation. With a code execution rates up to 96 million instructions per second, and outputs of up to 256 microsteps per step, commands are executed at high speed, optimising response times and control performance for demanding applications.
