Encoders with EtherNet/IP ports diagnose faults and monitor networks

At the recent SPS/IPC/Drives show in Germany, Sick unveiled its first rotary encoders with built-in Ethernet IP interfaces. The AFS60 single-turn and AFM60 multi-turn absolute encoders use the Ethernet interfaces for diagnostics and to monitor networks.

New steel process boosts bearing performance

SKF has developed a new method of processing bearing steel that it says will result in improved performance and longer operating lives, even in applications where there are high levels of contamination. It is using the new process to upgrade and expand the Explorer self-aligning roller bearing range, which it launched in 1999.

IP67 power supplies predict when they need to be replaced

Balluff has introduced a 24V DC industrial power supply that provides feedback on its real-time and long-term operational status, allowing replacement and maintenance times to be predicted. The Heartbeat supply uses three coloured LEDs to inform users about its load level, “stress level” and lifetime.

Laser gap sensor fills a hole in the market

Micro-Epsilon has developed a laser-based technology for measuring and evaluating gaps and edges in various surfaces. The non-contact gapControl 2711 system can measure gap widths and depths, height differences, centre positions, angles, flushness, proximity and overlapping edges. The sensors are also suitable for quality assurance and collision avoidance applications.

Energy harvesting transmitters open up new applications

EnOcean, the German specialist in self-powered wireless transmission technologies, has launched a third generation of mechanical energy converters which, it says, operate more efficiently, with less noise and higher load capabilities.

Integrated IE4 motor will cut energy costs `by up to 50%`

At the recent SPS/IPC/Drives show in Germany, SEW-Eurodrive unveiled an “electronic motor” that combines an IE4 permanent field synchronous motor, drive electronics and, optionally, high-efficiency gearing, to produce a drive system that can cut energy costs by up to 50%. The DRC integrated motor needs just one four-wire cable for both power and communications, cutting installation costs by up to 60%, SEW claims.

Acquisition delivers Ethernet servodrive

The first new servodrive to carry the ABB logo since ABB acquired Baldor last year, made its debut at the recent SPS/IPC/Drives show. The MicroFlex e 150 drive supports several Ethernet protocols and offers “universal” encoder interfacing.

Welsh firm gives elevator drives a lift

At the recent SPS show in Germany, the Welsh drives-maker Invertek launched a range of inverters dedicated to controlling lifts. The Optidrive Elevator drives (shown below) speed the commissioning process using factory-set parameters, while five independently adjustable S-ramps can fine-tune ride comfort. The drives can deliver up to 200% torque from zero speed, and offer a “rescue mode” using an external UPS.

Multi-axis module simplifies motion control

Mitsubishi Electric has added a “simple motion module” to its Melsec L series of positioning modules. The new module provides advanced functions such as speed and torque control, using simple parameter settings.

Freestanding enclosures share parts with bayed system

Rittal has announced a freestanding enclosure system that shares components with its TS 8 top enclosure system. Unlike baying suites with frames and removable side panels, the body of the new SE 8 system – consisting of two side panels and a roof – is made from one piece of sheet steel, reducing costs and avoiding the need to handle separate side panels. The rear panel is screwed on for easy access.
