Jumo expands its power

Jumo expands its power controller series The new power controller from ‘Jumo’ enables the actuation of three-phase loads with all operating modes and simultaneous detection of partial load failures. This new power controller is typically used where temperatures of 1400 °C and higher are needed. Silicon carbide and molybdenum disilicide are used as the heating elements. A further advantage is the “Teach-in” function, which allows the alarm limit values for the detection of partial load failures to be set automatically. The cyclical calibration ensures permanent and precise detection of partial load failure, even if the specifications of the heating element are changed. In future all the Jumo power controllers will be equipped with Ethernetbased communication protocol. This enables the constant transfer of process data such as load current, load voltage, and impedance. The real-time capability of the interface enables several power controllers to be synchronized in combination with the Jumo mTRON T automation system. The system is also capable of determining the overall output of the process and regulating the individual output of the power controllers to prevent it from exceeding the predefined current limits. This avoids energy peaks and reduces power costs. Compact, rugged, three-phase power supplies from Siemens Siemens has added two extremely compact, versatile devices to its range of power supplies. The new Sitop PSU300S with a 5 Amp rated output current and a width of just 50 mm, saves space on the standard mounting rail. It has also reduced the width of the 10 Amp version by 20 mm to just 70 mm. These devices need no lateral installation clearances from other devices. The high-performance power supplies can deliver 1.5 times the rated current for up to five seconds at starting loads. With their high efficiency of up to 91 %, both power supplies have low thermal losses in the control cabinet. The devices have a 3-phase AC input with a wide-range from 340 to 550V and supply a reliable 24 V even in the event of major line voltage deviations. With international certifications, such as ATEX, IECEx and GL, and an ambient temperature range from -25 to 70 °C these power supplies can be used worldwide in a wide range of industries. PRODUCT NEWS The Sensor design fit for almost every cylinder profile The MZT7 magnetic cylinder sensor from Sick, one of the world’s leading producer of sensors and sensor solutions for industrial applications. With its GMR technology, the MZT7 reliably detects the piston position in pneumatic drives. It can be mounted directly into all cylinders with standard T-slots. It is characterized by its simple mounting principle: Insert the sensor into the slot and rotate the locking screw a quarter turn to fix it securely to the cylinder. The company also offers an extensive range of adapters which enable the MZT7 to be used with other cylinder types. Its universal housing design compensates for the various slot dimensions from the widest range of cylinder manufacturers. And for cylinders without a T-slot, such as round, tie-rod and profile cylinders, an extensive range of mounting adapter accessories are available. AUTOMATION TECHNOLOGIES 1/2016

Exergen’s ‘Extreme’ sensor delivers accuracy even in severe conditions Exergen Global, an expert thermal solutions provider, announced the availability of its Extreme IRt/c, a non-contact temperature sensor. The Extreme IRt/c features a custom designed robust housing that protects the sensor from extreme vibrations, shift in pressure and other acute ambient changes. The sensor was originally developed for a defense contractor whose client needed to measure the temperature of equipment mounted on the exterior of the military aircraft. During the tests, Exergen found that its standard IRt/c sensors were drifting due to the extreme vibrations that occurs during flight. Exergen then came up with a customized mechanical design that heatsinked the body of the sensor, protecting it from vibrations and extreme temperature changes. “The Extreme IRt/c is an outstanding example of the way in which Exergen employs its ‘Senoranics’ methodology to develop unique temperature sensor solutions”, Said Bart van Liempd, CEO of Exergen Global. In addition to defense applications, the Extreme IRt/c is also well suited for semi-conductor manufacturing, in which air pressure, temperature and other ambient conditions undergo dramatic shifts. New vision sensor powered by in-sight Cognex Corporation announced the introduction of the In-Sight 2000 series, a product line that combines the power of its industry-leading In-Sight vision systems with the simplicity and affordability of a vision sensor. Ideal for solving simple error-proofing applications, these vision sensors set new standards for value, ease of use and flexibility thanks to the powerful combination of proven In-Sight vision tools, a simple setup, and a modular design with interchangeable lighting and optics. The In-Sight 2000 series includes an integrated, high-performance image formation system consisting of field interchangeable lenses and a patent-pending LED ring light that produces even, diffuse illumination across the entire image, eliminating the need for costly external lighting. Customers can easily swap out the lens and change the color of the integrated ring light as needed for their application. Together with the In-Sight Explorer EasyBuilder interface, the series allows even novice users to achieve extremely reliable inspection performance in nearly any production environment. Euchner’s transponder-coded safety switch Euchner is expanding its range of transponder-coded safety switches with solenoid and integrated evaluation electronics. The new CEM-C40 is used in applications requiring guard locking for process protection. The solenoid achieves a locking force of 600 N and effectively prevents safety devices from being opened unintentionally. When the safety guard is closed, the transponder signals are evaluated in the safety switch. If the signals match, the two safe semiconductor outputs are switched. When controlling the solenoid, the guard locking is activated and the locking force is tested. If the force is greater than 400 N, a status signal is transmitted to the control system. The CEM-C40 features adhesive-force adjustment. It can be adjusted in 3 levels from 0 to 50 N. It also features 2 x 4 LEDs in the housing. These LEDs are easily visible from all directions and display all important information about the device’s status. Electrical connection is realized simply via plug connectors. For larger installations with several safety doors to be monitored, up to 20 CEM-AR- C40 devices or other Euchner AR products can be connected in series. AUTOMATION TECHNOLOGIES 1/2016
