Carlo Gavazzi monitoring relays incorporate over and undervoltage, to protect the motors that keep an operation running. The current feature ensures overload protection while phase loss sequence ensures the correct rotation for generators and many more protection applications.
Directional control valves for pneumatic safety applications in five port two position sliding spool type with static seals, mounted on a safety manifold configured for three port two position operation. Each valve incorporates a two-pole positive driven plunger type switch with positive opening contact. The two models offered have certification to meet Australian & European machinery safety standards.
A non-contact coded safety switch, PSENcode, from Pilz is claimed to meet the highest requirements for safety gate monitoring, the highest level of security and 10 units can be connected in a single series.
The safety network controller (SNC) is a safety controller with a built-in DeviceNet safety interface. The SNC also features modularly con-figured safety functions for programming safety circuits. The controller meets SIL3 of IEC61508, the standard for funct-ional safety, and machine safety standard, category 4 of EN954-1.
Kiwi ingenuity is leading the way in the rail maintenance industry, with major safety initiatives developed by local rail maintenance workers being implemented not just on New Zealand's rail network
Carlo Gavazzi proximity sensors are rugged and flexible and are designed for reliable and accurate sensing in almost any application. The sensors offer detection without any physical contact and this in turn provides longevity for the device(s).
Turck announces the M12 eurofast junction boxes with stainless steel inserts have been added to the multibox family. All metal parts on these junction boxes are made of 316 stainless steel. The junctions are suitable for wire consolidation in environments where brass or other metal parts fail and are a cost-effective solution for harsh conditions.
The Siguard 3RG78 family of light curtains from Siemens Automation & Drives is suitable for personnel protection where presence sensing is necessary. The type 4 units are suitable for use in category 4 safety control systems. Resolutions from 14 to 90 mm and beam heights up to 3000 m provide reliable, fast detection.
Engineers, electricians and machine designers are often unaware that they personally have legal responsibilities under the Occupational Health and Safety Act and Plant Regulations
