SPS IPC Drives 2015 exclusive show report

03 January, 2016
to handle currents up to 1,250A.

The Italian sensor-maker Datalogic was showing two new ranges of safety light curtains. The Slim family covers 34 heights (150–1,200mm) and three resolutions (14, 24 and 34mm), and can be embedded into machines where space is limited. Datalogic claims that its new SG4-H curtains are the first to offer stainless-steel housings and glass windows. The IP65/69K curtains are aimed at hygienic applications subject to frequent cleaning with corrosive detergents.

Eaton has announced its first fuse-equipped NH switchgear that can be connected to its SmartWire-DT system as standard. This is achieved by plugging a communication module into the NH XNH fuse disconnectors, allowing the fuse status, switch position, and power values to be monitored, and the data transmitted via gateways to all common fieldbuses. The switchgear, available in four sizes and with one to four poles, also includes a LED to indicate fuse failures.

The safety specialist Euchner had several new arrivals on its SPS stand, including: a transponder coded safety switch with a solenoid and built-in evaluation electronics (CEM-C40); a version of its CTP safety switch that can be used directly with AS-Interface Safety at Work installations; a variant of its CKS electronics key system that support AS-i; a version of its MGB guard locking and monitoring system for safety doors that supports EtherNet/IP (below); and a modular version of its EKS access management system that has a Profinet interface.

Euchner also announced a series of expansion modules for its MSC modular safe control system that are designed to safely monitor speed, standstill, speed ranges and direction of rotation.

The UK’s Fortress Interlocks unveiled a pair of devices aimed at hygienic and food applications: the amGardncs coded, non-contact proximity switch with an IP69K stainless-steel housing, for use where precise guidance of guards could be difficult; and the amGardS40 stainless-steel interlock. Fortress was also showing a Profinet/Profisafe communications module for its amGardpro interlocks.

New from Kübler is a module for monitoring voltage, current and temperature safely. The Safety-M EMIO.SAI.200 can monitor and process two analogue signals simultaneously, and generate a safe signal from them. It can, for example, monitor minimum and maximum values.

Leuze has developed an RFID-based safety locking device which cannot be opened by a similar device. The IP67/69K L300 series actuators, which can have millions of different encodings, can produce a locking force of up to 7.5kN and comply with SIL 3 / PL e. Leuze also announced a safety laser scanner which provides 100 reversible fields or 50 reversible quads and up to 10 sensor configurations.

Murr launched a series of power connectors for motors (shown below) including an M12 version which, it claims, is the smallest and most powerful five-pole M12 connector available. The connector can handle 2 x 16A at 63V AC/DC. There is also an M15 version with reverse polarity protection of asynchronous motors up to 7.5kW, and an eight-pole M23 connector for high-performance drives and servomotors.

Other new arrivals on the Murr stand included a series of emergency-stop and reset buttons with M12 ports, claimed to save time and eliminate errors, and new three-phase Emparro power supplies for 24V applications, which have an efficiency of up to 95% and a claimed MTBF of about 1,000,000 hours.

Rittal says it has doubled the luminous power of its enclosure lighting, as well as providing more even lighting, by adopting an innovative LED-based technology. It adds that the enhanced lighting will make assembly and servicing easier. The new lights use the same electrical and mechanical connections as
